    Ecoflow’s products are designed to be simple, efficient and easy-to-use portable power and solar charging systems that integrate with one another.

    Taking this one step further, they have also created what they call the world’s first ‘Smart home ecosystem‘.

    In plain English means that they offer a range of virtually ‘plug-and-play’ solar power and home energy systems with either the Delta Pro, or their latest system called Power Kits, which require little to no technical expertise to set up and use.

    This has numerous applications, including running a tiny house or cabin off the grid, or setting up a version of this system in your RV, travel trailer or camper van to live and travel in off-grid without ever having to plug in to a campground outlet. Hello, boondocking!

    Ecoflow’s portable power stations

    Ecoflow offers two families of portable power stations, the Delta and the River.

    Within each product family, the units range from the ‘pro‘ to the ‘mini‘ – these terms relate to the total amount of power storage capacity the unit has, among other things.

    So for the Delta range, you can choose from Delta Pro, Delta Max, Delta, and Delta Mini.

    As a general rule, the larger the unit, the more storage capacity it has, and the larger units have a larger number of outlets, can output a higher wattage, and can charge with higher wattage inputs.

    The larger units, and in particular, the Delta Pro, have a load of extra features and capabilities that I cover more later in this Ecoflow review.

    Delta Pro vs River Pro

    As I personally own and use the Delta Pro and the River Pro, in this review I also provide a comparison between the two, which I hope you’ll find helpful.

    If you’re choosing between the different sizes of Delta and River power stations, there are quite a few options to choose from.

    Related Reading:

    The best way to compare the features of all the different Ecoflow units is to visit this feature and price comparison page on their website.

    On this portable power station comparison table, you can see if the units you’re choosing between have all the specifications and features that you’d want, depending on how you may plan to use your portable power station.

    Different use cases for a solar generator portable power station

    You can use one of these wherever you may need or choose to want to use power without relying on the electricity grid.

    Examples of when you may want to use a solar generator and / or a portable power station are for camping / glamping, RV / Vanlife, home backup in power cuts, blackouts or emergency situations, off-the-grid living, charging and using electrical devices when you have limited access to a wall outlet.

    You can charge these units using a regular wall outlet when you’re back home, plug them into your car or RV to charge the battery while driving, or charge them using solar panels that Ecoflow also sells as part of their portable power packages.

    Ecoflow Delta Pro Review

    Let’s kick off our first product in this Ecoflow review, the Delta Pro.

    About the Delta Pro and what it’s best for

    The Delta Pro by Ecoflow is a true beast of a portable power station. It can power your entire home!

    The Delta Pro is, quite simply, the most powerful, versatile portable power station I know of with inputs and outputs galore, including 5 AC outlets, 2 USB-A ports, 5V, 2.4A, 12W Max per port, 2 USB-C ports, 5/9/12/15/20V, 5A, 100W Max per port, DC5521 Output, 2x USB-A Fast Charge, and a Car Power Output for ev car charging, so you can use it as a portable EV station of sorts.

    You can also charge your Delta Pro at an EV station.

    I love that Delta Pro supports such a wide array of outputs – this will suit so many requirements that people may have.

    You name it, and the Delta Pro can do it, when it comes to powering your home or work energy needs that require AC outlets or even USB-C which is getting more and more popular for supplying enough power to high-powered gadgets like laptops and cameras.

    A big differentiator for the Ecoflow Delta Pro is that it’s not just a standalone device, (although it can be used that way to great effect).

    What makes it even more versatile is that it can form the foundation for your home’s entire energy system – which I explain in more depth later in this review.

    Delta Pro’s Key features

    See the Delta Pro product page on Ecoflow’s website for the full list of features and functions, as there are too many to list them all, however these are the key features that stand out to me:

    The starting capacity of the Delta Pro is 3,600wh.

    ecoflow, delta, 2000, tested, reviewed, camping

    If you add an extra unit, batteries and generators you can get this all the way up to 25,000wh! This means that the Delta Pro will power your entire home for days.

    With on Delt Pro unit, you can power up to 4500w of appliances. You can run your refrigerator plus connect a load of other things such as lights, chargers and other devices to it and not run out of power over a few days.

    Delta Pro has SO MANY ports, meaning you can have up to 15 devices connected to it and running or charging at the same time (assuming they don’t exceed 4500w at one time).

    You can control it remotely using Bluetooth and the app, and you can also get a remote control to use with it.

    There are multiple charging methods for Delta Pro:

    • It’s compatible with a range of solar panel brands (or you can get Ecoflow solar panels like we use) and can take up to 1600w of solar-powered charging
    • You can charge it at any AC level 2 EV station locations throughout the US!
    • Simply charging off a regular wall outlet takes less than two hours.
    • You can plug it into your car’s 12v outlet to charge it while the engine is running.

    Delta Pro is pretty rugged, fire-resistant, and has a load of cooling fans which do come one when using most of the multiple charging methods listed above but also when delivering power via AC output.

    The cooling fans are necessary to keep your Delta Pro running properly and safely.

    This does, however, mean it makes a fair amount of noise when charging and running but it only runs when the Delta Pro system recognizes it needs cooling.

    It’s powerful enough to power items such as an AC unit (like the Ecoflow Wave – more on that, in my Ecoflow Wave review below) kitchen appliances, and a hairdryer, as well as everyday charging and power for smaller items such as your laptop, phones, headlamps, television, internet router, and lights.

    There are some stats on Ecoflow’s website that provides more examples with rough estimates of the number of hours and charge cycles you can get for various devices, which will provide you with an even better idea of what the Delta Pro portable power station can do on one charge.

    One (perhaps obvious) drawback that should be expected with such a large battery and portable power generator, is that it’s very heavy! 99lb, to be exact.

    It has wheels and a luggage-style pulling handle, but trust me, unless you’re very strong then you’re not going to want to lift it or carry it very far.

    I also really like that the Delta Pro can be placed on its side which makes access to the most popular ports much easier.

    If you’re looking for a portable power station that has more ease of portability for road trips and camping, then check out my Ecoflow River Pro review below, as this smaller power station may do everything you need, at a smaller size and lower price point.

    Cost and where to buy Delta Pro

    We recommend buying the mighty Delta Pro from the website to ensure fast delivery and a 24-month warranty period – they also seem to offer the cheapest right now.

    Delta Pro is also available at the stores below:

    Using the Delta Pro ecosystem for off-grid and home backup power

    Essentially, depending on your needs, just having one of these Delta Pros will provide a load of portable power for many uses and situations.

    However, if you’re looking for even more – more power storage and more time to run electrical systems while off the grid, then you can expand the ‘ecosystem’ with add-on units.

    For example, for each Delta Pro unit, you can also get two large add-on batteries to add to your storage capacity.

    The batteries work together with the Delta Pro, so you have one unit to pull power from and control.

    You can take this even further by using Delta Pro power stations and Smart extra add-on batteries as the basis for creating an entire home (or off-grid cabin or tiny house) backup power system.

    Benefits of the Ecoflow Home Backup Power System

    With one of these installed, you can power your home for days.

    You can do that just with the standalone portable power station like a Delta Pro, but the home backup system offers smarter, seamless functionality.

    Having one of these set up allows you to run your home as you would normally, including all your wall outlets and light fixtures, which wouldn’t work in a blackout otherwise.

    Related Reading:

    I had been contemplating the merits of a Tesla Powerwall for some time, however, this Ecoflow system has more versatile applications and can also do similar things.

    These things include powering charging of your EV at home and, of course, charging from the sun at home, so I’m leaning this way as I have half of the equipment for it already and it’s more versatile for my needs.

    To use my Delta Pro system for home backup I will need some extra parts, including the Smart Home Panel that provides the connection between the Delta Pros and a home’s electrical system.

    Once this is installed, then it should seamlessly (and automatically) switch over my home’s power source from the grid (for example, if the grid goes down in a blackout), to 2x Delta Pro Power Stations.

    Another efficiency benefit of having this installed is that I can also run my home’s power from the Delta Pro system during peak hours, and save on paying higher for taking energy from the grid.

    Then, the battery can charge up at low-usage hours (such as in the middle of the night) when electricity is cheaper.

    Needless to say, I’m pretty excited about the possibilities this system has to offer!

    So, if I get this up and running in the future then I will be updating this Ecoflow review to share my experience of the full home backup setup.

    Ecoflow River Pro Review

    The Ecoflow River Pro is a great size portable power station for running and charging smaller devices during blackouts, camping weekends and road trips.

    It is easy to carry around both in terms of size and weight, and versatile in terms of the ways in which you can charge it (as well as offering a super-fast charging time), and you can connect multiple devices to it at the same time to run or charge them.

    Key Features of the Ecoflow River Pro Power Station

    The River Pro comes with a 720wh capacity and weighs 16.8lb.

    Like the Delta, the River Pro also has expandable capacity when you also buy a River Pro add-on battery. This doubles the capacity to 1440wh.

    It also has ten ports for charging. This includes three regular AC (wall) outlets, a USB-C port, three USB-A (regular USB) ports, of which one is for fast charging, plus DC/12v outlets.

    Like the Delta Pro, you can monitor it using the Ecoflow app and a Wi-Fi connection.

    Related Reading:

    Regular AC output on the River Pro is 600W, which can be boosted for short periods up to 1800W – what the company calls ‘X-boost’.

    According to Ecoflow, the River Pro offers the world’s fastest charging!

    This power station can charge from a wall outlet from empty to 80% in around an hour, and just over an hour and a half gets it to full charge. Other ways to charge it include using your vehicle’s 12v outlet, and solar charging.

    It also has a handy light built into it.

    In terms of what devices you can power with this and for how long, it really depends on the mix of what you are using.

    However, in general, a power station of this size (nice and portable when compared to Delta Pro, and other portable power solutions for that matter), it’s best at powering and charging smaller devices such as phones, laptops, CPAP machines, and batteries for cameras and rechargeable camping lanterns.

    ecoflow, delta, 2000, tested, reviewed, camping

    This is why it’s ideal for camping and travel.

    You can absolutely use the River Pro for powering things such as electric cooktops and other cooking/heating appliances, but this will quickly run down the battery, which is not what you want in an off-grid or blackout situation.

    Therefore, if you’re looking for a larger capacity portable power station to power appliances and cooking, heating or cooling equipment then something like the Delta Pro is going to be more suitable.

    Using Ecoflow River with Solar Charging

    A set of portable, fold-out solar panels is therefore a great companion to the River Pro for off-grid use, such as camping. It has a solar charging input of 200W.

    To charge my Ecoflow devices using the solar input, I have Ecoflow’s 220w bifacial portable solar panel set.

    The bifacial solar panels have panels on the back side, as well as the front. They are designed to capture additional solar charge from ambient light.

    The ambient light is stated to provide up to an additional 25% solar energy charge.

    This is great, because if you’ve used solar panels before then you’ll know it’s typical that you won’t get all that close to your panels’ total wattage input unless you’re in absolutely perfect solar charging conditions, so this boost helps get you that much closer.

    This portable solar panel has an IP68 rating which means it’s waterproof and dust-tight, and therefore suitable for environments where it’s likely to get that type of exposure.

    Cost and where to buy the RIVER Pro

    We recommend buying the mighty Ecoflow River Pro from the website to ensure fast delivery and a 24-month warranty period – they also seem to offer the cheapest prices.

    Ecoflow Wave Air Conditioner review

    I’d been holding out for an Ecoflow Wave AC unit ever since I heard that it was launching in 2022.

    The Ecoflow Wave is not just a portable AC unit, but it’s the most powerful air conditioner of its size.

    And, importantly to me, it’s small and portable enough to take on road trips and camping in our camper van – great for keeping us cool in the California heat.

    We also use the Ecoflow Wave while driving in our van to ensure our adventure dog Kepler doesn’t get too warm while traveling in the back, where the van’s own AC doesn’t reach.

    Key features

    When used on its own, this portable AC unit runs by plugging it into a wall outlet, or, perhaps your Delta Pro portable power station.

    You can also buy an add-on battery for the Ecoflow Wave, which I highly recommend as it transforms this AC unit into a truly portable AC Unit with around 3 hours of run time on a single charge.

    This battery attaches neatly to the bottom of the AC unit simply by slotting the Wave onto and sliding it back until it clicks into place.

    Then you just plug the battery into the Wave unit, and things just work with no hassle whatsoever.

    It’s definitely worth getting if you want to be able to use this portable AC unit without mains wall outlet power and take advantage of the ability to charge the battery (to power the unit) using solar charging panels.

    The Ecoflow Wave kicks out 4000BTUs worth of cooling, and, unlike many other AC units, it doesn’t accumulate water or require you to collect or empty a condenser container.

    Like other compressor-driven cooling devices, it does generate hot air, which blows out of the back (while the cooled air blows out the front).

    The Wave comes with two directional ducts, which can be attached for evacuating warm air out of the back, or focusing the cool air flow towards you.

    One thing I wish the Wave had was bi-directional vents on the front – as it stands, you can only direct the air up or down, whereas it would be nice to also be able to point the air to the left or right.

    See examples on the Wave AC Unit product page showing how it can be used.

    I’ve found that if you’re using it in a house then to get the most efficient cooling of your room you definitely want to use one of these ducts to divert the warm air from the back of the unit out a window or door.

    The Ecoflow App can also be used to control the temperature fan speed, and timer of the Wave AC Unit remotely which is pretty cool. I also like how the app shows all your portable power stations in there too, with their power usage stats.

    Using the Wave as an off-grid, solar-powered AC unit

    Depending on the battery you use, the Ecoflow Wave Air Conditioning unit can run for between three and 12 hours, or for as long as you like if it’s plugged into AC power.

    Plus – it’s smarter than a standard air conditioner unit. It can intelligently mix fan and cooling settings to extend runtimes beyond what would usually be possible too.

    This is great if you want it to say, run overnight, but don’t think the battery will last with just the AC blowing all night.

    To charge the add-on battery using solar power, it can take as little as five hours using 200w of solar panels, although that of course assumes ideal sunlight conditions.

    Even so, it’s pretty awesome that I can charge and run something as powerful as an air conditioning unit in an off-grid context, especially if you need it for camping in the heat.

    It’s also super useful during blackouts, which tend to happen in periods of very hot weather (at least where I live in Northern California) – exactly when you may want to enjoy some AC!

    Cost and where to buy the Wave AC Unit

    We recommend buying the mighty Ecoflow Wave AC Unit from the website to ensure fast delivery and a 14-month warranty period – they also offer the cheapest prices.

    EcoFlow Goes All In With Its Latest Delta Max Pro Power Stations

    EcoFlow recently released its latest Delta power stations, also known as solar generators.

    The Delta Max and Pro are some of the largest power stations on the market in terms of battery capacity, and EcoFlow advertise these as the ultimate battery backups for power outages and emergencies.

    Since we’re RV travelers, we use our power stations to power our whole RV and electronics on the go, no matter where we are. All it takes is this 15A to 30A adapter.

    Paired with a couple of solar panels, it fills all of our electricity needs.

    EcoFlow has let us test the Delta Max for a couple of weeks now, and it’s time to review it.

    We were sent the Max 2000, which has 2016Wh. There is also a smaller 1600 with 1612Wh.

    The smaller one has a weaker inverter (2000 vs 2400), but other than that they are very similar.

    Without further ado, let’s get to our review of the Delta Max.

    EcoFlow Delta Max 2000 – Specifications Features

    Last update on 2023-06-29 / Affiliate links / Images from Amazon Product Advertising API

    Battery Capacity

    The Delta Max we got, the 2000, stores 2016 watt-hours.

    With that much electricity, you can power a 1500W microwave for 1.5 hours, or an air conditioner for 1-2 hours depending on the size.

    Plug in a 1800W space heater and it will run for about 0.8 hours.

    But these are obviously not meant to be used to heat up or cool down your house or camper, unless you absolutely need to.

    It will last for days if all you need to do is run a coffee maker and toaster in the morning, then be on your computer all day while charging your portable devices.

    It’s easy to find out how long a specific device will last when plugged in to the Delta Max.

    If you know how much electricity your device require, you can divide the total watt hours by the required wattage, then multiply by the inverter efficiency.

    For example, my MacBook Pro has a 100W charger. So the math would be: 2016Wh/100W0.85=17.1 hours.

    Since my MacBook lasts a full work day on a full battery and only takes two hours to charge up, the Delta Max would last a full week.

    Inverter/AC Outlets

    I have seen power stations with 20A outlets before, but none of them have been able to actually output 20A.

    The Delta Max can do up to 2400W, which is exactly 20A.

    That means that it can power not only microwaves and residential refrigerators, but washing machines and ovens as well.

    The pure sine wave inverter powers the six AC outlets, and remember that it can output up to 2400W in total, not to each port at the same time.

    There is also a mode called X-boost that increases the output wattage to 3400W.

    EcoFlow does not guarantee that this works with every appliance or device that requires a high wattage above 2400W.

    It has become clear to me that EcoFlow likes to push the envelope when it comes to how many ports you can put on a power station.

    The Delta Max has almost twice as many ports as some of its biggest competitors.

    Six 20A AC outlets, six USB ports, three DC ports, and two battery chaining ports.

    Four of those USB ports are USB A, and two are USB C.

    The USB C ports can both output up to 100W, which is powerful enough to charge the latest laptops, tablets, phones, and consoles that support USB C charging.

    A regulated 12V cigarette port makes it easy and safe to plug in a 12V fridge, and we didn’t have any issues powering our BougeRV CR45 fridge/freezer.

    There are also two 5.5mm DC outputs that can be used to power small electronics with that type of input. EcoFlow includes a DC cable for this purpose.

    On the side, you’ll find two battery ports where you can connect two EcoFlow Smart batteries (click to view on Amazon).

    If you add one battery, you’ll have a total of 4032Wh. If you add two, a total of 6048Wh.

    The Smart batteries are also capable of fast charging.

    The backlit display tells the input/output watts, battery percentage, hours to empty/full, active ports, and Wi-Fi status.

    For better monitoring I recommend using the EcoFlow app.

    The Delta Max has built-in Wi-Fi, just like the Delta Mini.

    This lets the Delta connect to an existing Wi-Fi network and be monitored and controlled remotely.

    In the app, you can not only monitor input/output watts, active ports, battery percentage and temperature, but also change several settings.

    Charging/Solar Capabilities

    The Delta Max 2000 can recharge in 1.8 hours, and do 0-85% in just 65 minutes. That is extremely fast for a power station and I haven’t seen any other brand come close to that.

    But of course you can also charge via solar or the included car charger.

    When it comes to solar, it has an MPPT solar charge controller that will charge the battery efficiently when using solar panels.

    The solar charge controller can handle voltages between 11-100V, up to 10A, and 800W max.

    Therefore, if your panel(s) are going to output more than 10A they should be wired in series and not parallel.

    As long as you make sure the total voltage of your panels aren’t going to exceed 100V, you’re safe. That means you can use not only 12V panels, but 24V as well.

    If you’d like to connect third-party panels with MC4 connectors, you can, and it’s very easy to do since EcoFlow includes an MC4 to XT60 adapter.

    Note that a lot of popular foldable and portable panels do not come with XT60 connectors, but some of them use MC4 connectors.

    If you’re considering purchasing a specific panel or two and want to make sure it’s compatible, please leave a comment.

    One new thing EcoFlow has added to the Delta Max is the possibility to add more batteries.

    It now sells the EcoFlow Smart batteries (click to view on Amazon), which are easily connected to the Delta Max. Connect one to double the battery capacity, or two to triple it.

    These Smart batteries charge just as fast as the built-in battery.

    EcoFlow includes a wall charger, car charger, DC5521 to 5525 cable, and an MC4 to XT60 adapter.

    My Review Of The EcoFlow Delta Max 2000

    What I Like

    Lots of battery capacity possibility to add more

    As somebody that has been traveling full-time in an RV for over two years and spent a lot of time boondocking without hookups, I know that my wife and I use a lot electricity.

    The 2016Wh found in the Delta Max are enough to last us 2-4 days depending on how much time we spend on our computers and how many kitchen appliances we use.

    My estimate includes the use of a coffee maker, toaster, air fryer, and TV.

    You could buy several small power stations instead of one heavy one, but I like that this has everything we need.

    I also like that you can add more batteries. We don’t feel the need for it right now, but we might do it in the future. Especially if we live in a house and have a Delta for backup power.

    Very powerful inverter

    We have never reviewed a power station that can output 20A, so I have to mention how great it has been.

    Whenever we use the RV microwave with our other batteries, we have turn off everything else that uses around 200-400W for it to not overload. With this 2400W inverter, we haven’t had any issues powering the microwave and other things at the same time.

    Most of our power stations can’t even run the RV microwave in the first place.

    We haven’t used the X-boost mode much, since we don’t have anything that requires that much power except the RV AC.

    Extremely fast charging

    The fact that it can be fully recharged in less than two hours is incredible, and especially great for us.

    We usually have enough sunny days for our solar panels to keep the Delta Max charged up, but when we don’t we only need to turn on the onboard RV generator for an hour or two to top it off.

    That simply hasn’t been possible before, well at least not until we got the EcoFlow Delta Mini last year.

    One thing I do want to mention though, is that sometimes the battery thinks it’s at 100% and fully charged, but then when we start using it, it drains quicker than usual and I suspect that the BMS thinks it’s fully charged and stops it from continuing even though it isn’t.

    It seems like a software issue, and it doesn’t happen all the time, but I will keep you posted here and let you know if I find a solution.

    We have gotten used to monitoring the Delta Mini with our phones, so it’s great that the Max has the same features and can be monitored with the same app.

    Having Wi-Fi on does seem to drain the battery, but it’s just a matter of a couple of percentages everyday.

    That is something you should be aware of though, since some might leave the battery in a closet and have a dead battery when they go get it during a power outage.

    Our solution has been to turn off the power station completely while we don’t need to use it, like when we’re at an RV park or gone from the RV for a couple of days.

    So if you’re going to use it as a backup, keep it plugged in so it can charge, or make sure it’s completely turned off.

    MPPT solar capabilities

    An MPPT solar charge controller is a must in 2022, so I am glad but not surprised that the Delta Max has one.

    I haven’t quite made up my mind about the solar. On one hand it’s great that it can handle up to 100V and 800W, but on the other hand the 10A limit bothers me.

    Mostly because I hear a lot of disappointment from people that already have a couple of panels that can’t be wired in series, so they’re stuck with the 10A limit and no options except buying more panels.

    As I mentioned earlier, as long as you’re aware of it and plan accordingly, it’s not going to be a problem.

    If you’re not sure what panels you should get, please leave a comment and tell me what and how you plan on using the Delta Max. I’ll do my best to help you find the right panel(s) for you.

    Number of ports what they can output

    I’m of the opinion that you can’t have too many ports on a power station.

    Both my wife and I charge our laptops via USB C, and the fact that the Max has two 100W USB C ports is excellent.

    On the other side of the unit, there are a whopping six AC outlets. I wish Goal Zero would use one of these for a weekend and realize how convenient it is to not have to spend your trip constantly plugging in and unplugging cables.

    Regulated 12V

    Just like the MPPT solar charge controller, I think a regulated 12V port is a must in 2022.

    Nothing new here, just a functional port that can power 12V fridge/freezers, CPAP machines, etc.

    I’m not going to say it’s a light power station, but it’s not that heavy for what it has inside.

    The permanent handles make it easy to carry around, and the slim design further improves the portability.

    The included accessories

    Last but not least, I have to give EcoFlow praise for including the cables you’re going to need to use it.

    Wall charger, car charger, MC4 to XT60 adapter, and a DC cable. It doesn’t have to be more complicated than that, but for some reason most companies can’t even include that.

    What I Dislike

    There are not a lot of things I dislike about the EcoFlow Delta Max, but there are three things I want to mention.

    Uncommon input port

    EcoFlow has been using the XT60 for years now, and I do like it since it’s very easy to connect and disconnect.

    To make it possible to connect third party panels that use MC4 connectors, EcoFlow includes an MC4 to XT60 adapter, which I will always give them praise for.

    However, a lot of the portable solar panels on the market that come with several different DC connectors do usually not include one of these XT60 adapters.

    This might as well be a complaint to the companies that sell these solar panels, since the XT60 has been used by EcoFlow for a long time now and has become an established brand on the market.

    10A input limit

    You should always know what you’re doing when you connect solar panels to a power station – and then this wouldn’t be a problem – but it’s still limiting that the charge controller has a 10A input limit.

    If you have several panels that add up to more than 150W, they should be wired in series and not parallel. Just make sure the total voltage is within the 11-100V range.

    As long as you’re aware of this before you buy panels, you’re fine, which is why I wanted to mention it again.

    No 30A port

    While EcoFlow has added a 30A port to the more capable Delta Pro, the Delta Max doesn’t have one.

    I understand why since the inverter is rated at 2400W (20A), but with the X-boost it’s supposed to be able to do up to 3400W (28A), which is why a 30A output could’ve been useful.


    We like the Delta Max, a lot. It’s the best power stations we have ever tested, and it has everything we need.

    There are a couple of small bugs and annoyances though, like how the battery sometimes thinks it’s fully charged when it isn’t, and how the Wi-Fi will drain the battery even if it’s not in use.

    It wasn’t enough of a problem to us during our tests to where we had to make a big deal out of it, but I want to be honest.

    From here, the only thing we would need is more battery capacity, fortunately EcoFlow sells the solution, the EcoFlow Smart batteries which would double or triple the total capacity.

    Currently, with the way we are traveling and living now, the 2016Wh is enough though. Especially since we have 200W of solar panels that can recharge the Delta as long as the sun is shining.

    So should you buy it? Well, it really depends on what you need. If you just need a portable battery for weekend trip to charge your phone, tablet, and laptop, this might be overkill.

    For those needs, the smaller River Max or Delta Mini is probably enough.

    But if you know what you need and are looking at a similar power station by a different brand and wondering if it’s worth it for the extra ports and features, I would say yes. Totally.

    Frequently Asked Questions

    How do you chain more batteries to a Delta Max?

    EcoFlow sells the EcoFlow Smart batteries (click to view on Amazon) that can be connected to expand the battery capacity of the Delta Max.

    EcoFlow DELTA Pro Power Station


    Shift In Innovation

    There had been a notable trend among the power station landscape over the past, few years that had perhaps been fueled by climate change, emergency preparation, looming threat of war, and the COVID-19 pandemic. Where manufacturers had focused on putting out “solar generators” — which really are just battery power stations that could be recharged with solar panels — with ever-increasing specifications that outdoor enthusiasts like me had been drooling over, I have been noticing a shift from the outdoors into the home. For instance, market leader Goal Zero has excellent batteries, solar panels, accessories, and integration kits, but many would be hard pressed to know that their products can also power an entire home or RV.

    Goal Zero Yeti 1500x 500x, Jackery Explorer 1000 300

    I have been observing friends and family thinking about having home solar panels installed to reduce their dependence on the local electric utility company, but short of purchasing a large battery from LG or Tesla Powerwall to store excess energy, they would still draw from the electric grid when the sun was not out at night. On the same note, a power outage would ironically also leave a solar-powered home without electricity. Those large LG/Tesla batteries are expensive, can only be installed by professionals, and may need to be replaced every ten years. So, what should you do? I would opt for a portable power station with a home integration kit from Goal Zero. Why? After the initial installation by a qualified electrician, you could modularly replace any end-of-life batteries yourself and even take the main Yeti power station unit camping. Flexibility!

    However, a boondocking friend of mine urged me to look at the high-capacity, modular EcoFlow Delta Pro (LiFePO4) battery. I did. And I was amazed by its feature set. I had also come across Jackery’s sister company, Geneverse (formerly Generark), who has the unique-looking HomePower Two (NCM) aimed at homes. Bluetti also has its EP500 (LiFePO4). All of that helped me realize an expanding market geared towards emergency preparation for the homeowner and/or recreational vehicle (RV) enthusiast. Good! Competition is great! Goal Zero, you have some work cut out for you there!

    Delta Pro: Front, Internal, Back /EcoFlow

    What are the differences? How do they compare to the Jackery Explorer 1000? I am a fan of both Goal Zero and Jackery as both bring their own advantages and disadvantages. Goal Zero and Jackery/Geneverse only had Lithium-ion Nickel Manganese Cobalt (NMC) battery offerings whereas Bluetti, EcoFlow, and BigBlue had Lithium-ion Lithium Iron Phosphate (LiFePO4 / LFP). The latter battery chemistry is less volatile (safer), more usable in extreme temperatures, and has a higher charge cycle count (battery lifetime). I will go over the differences towards the end of this article for those who want to know more.

    LiFePO4 batteries are less volatile (safer), more usable in extreme temperatures, and have a higher charge cycle count (battery lifetime) than NMC.

    I went for the EcoFlow Delta Pro Power Station and their 220W “Bifacial” Solar Panel (Review) for use with our vacation home merely because their feature sets looked so interesting. This two-part review will first go over the Delta Pro Battery and be followed by the 220W Bifacial Solar Panel.

    In A Nutshell

    The EcoFlow Delta Pro packs so many features and nuances, it took a surprisingly long time to summarize my thoughts for this review. It is one HECK of a beast of a power station! Although I was not able to test many of the capabilities due to my limited budget, reading and researching about some of the functions kept me in awe.

    EcoFlow 220W Bifacial Solar, Delta Pro

    Goal Zero had been the gold standard for a long time with its market leading quality, safety record, and philanthropy roots, but the Delta Pro definitely should put the company on notice with an ecosystem that surprisingly surpassed Goal Zero’s in many ways. Offering a 3,600Wh battery capacity that could be expanded to 25,000Wh nearly doubles what Goal Zero could currently offer at 15,671Wh, and its AC inverter leapfrogs Goal Zero’s 2,000W of continuous power and 3,500W surge with double that: 3,600W and 7,200W, respectively. What that translates to is more devices and appliances that can be left running for many more days than homes with the Tesla Powerwall or large LG batteries commonly paired with home solar panels.

    Sweet Spot: The 1000Wh battery capacity hits the sweet spot for many consumers, including this author, who are looking for the right balance of power and portability. But when it comes to home integration, the more Watt-hours a battery ecosystem offers, the longer one can power a home for during a blackout.

    Specifications and numbers aside, the Delta Pro has an impressive set of input (charging) options, including AC wall, EV charger (a first!), solar, DC-producing gas generator, and possibly a wind turbine in the near future. What wowed me was the Rapid charging capability when specific EcoFlow products are combined: 6,500W! Goal Zero’s best only charges at 600W, and two years ago, THAT number dropped my jaw. Charging a Delta Pro and Smart Extra Battery (7,200Wh) at 6,500W would take them from empty to full in less than 2 hours — SUPER impressive! Goal Zero’s 600W would have taken over 10 hours.

    What additionally sets the Delta Pro apart is its Double Voltage Hub that can double the capacity and output of various Delta Pro product combinations. Tack on the Solar Tracker that uses a top-mounted sensor to follow the sun for maximum exposure, a Smart Generator that uses gasoline to produce DC power to directly feed into the Delta Pro, and you have a good support system to maximize battery capacity to run appliances with for longer, if not infinite, time periods.

    A large, colorful display provides information about the battery’s status, and although it is beautiful, it lacks the details that Goal Zero’s higher-end products provide. EcoFlow makes up for that with its gorgeous smartphone app that also tracks historical data to help the owner make a variety of decisions from.

    I really like the telescoping, retractable handle built into the EcoFlow: extend it to one of two lengths to tilt the battery backwards, then pull and roll the 99-pound Delta Pro across the house — at least, that’s the theory. Dragging the heavy battery on uneven grounds (like gravel) or traversing stairs is a huge challenge with the Pro’s small wheels. Did you notice the weight I had just mentioned? Ninety-nine pounds is no joke for the average person to carry up a flight of stairs! Goal Zero’s Roll Cart, on the other hand, with its larger wheels conquer those obstacles and surfaces with much more ease.

    The EcoFlow tries to shed some of its LiFePO4 battery weight and cost by using a mostly plastic exterior. Although the Delta Pro still looks quite nice, Goal Zero’s Yeti X series is housed in a mostly metallic enclosure that helps dissipate heat and is more durable. Metal withstands impact force better than plastic, no doubt about that, but also adds weight. Two distinctive, exterior design philosophies each with their own pros and cons. Delta Pro is physically larger than the higher-capacity Yeti 6000X (6,071Wh), for some reason.

    EcoFlow Delta Pro vs Goal Zero Yeti 6000x

    What surprised me despite all the impressive features of the 3,600Wh Delta Pro, it still costs just a little more than the lower-capacity, 3,032Wh Goal Zero Yeti 3000x. That makes it a great value!

    Overall, it both pains and delights me to see the Delta Pro kicking Goal Zero’s Yeti X line to the curb. On one hand, Goal Zero now painfully looks a bit outdated, and on the other hand, Delta Pro has set a new bar that slaps Goal Zero in the face to wake up and innovate. Competition is always good for the consumer, and so, Goal Zero, what will you do next? EcoFlow has a winning product portfolio on its hands that is difficult to beat.


    As one of Time Magazine’s “Best Inventions of 2021” under the “Sustainability” category, EcoFlow’s Delta Pro power station deservedly turned some heads. It certainly caught my attention with its wide list of features, expansion options, and accessories primarily geared for home use. Market leader, Goal Zero, offers a similar range of products, but EcoFlow does so in a sleeker — and at times more innovative — package. The configuration options gave me some struggles to write about while researching the Delta Pro because there were so MANY, most of which I could not test because it would have cost over 30,400 to collect the entire ecosystem for the “full experience”! Perhaps EcoFlow could sponsor a few items to review someday? (Wink, wink)

    Bear with me! There is a LOT to discuss because of EcoFlow’s vast ecosystem of products. I will attempt to summarize the important ones and how they work with the Delta Pro.

    Delta Max vs Pro: The Max is a smaller, lighter version of the Pro with less capacity at 2,016 Wh, a smaller AC inverter, and no transport wheels.

    Battery Capacity

    The Delta Pro offers 3,600 Watt-hours of battery capacity — how long something can run for — that can be expanded with up to two EcoFlow Smart Extra Batteries (3,600 Wh each) for a combined total of 10,800 Wh simply by connecting them with a pair of cables. That could power a typical home drawing 750-1,000W of power per hour for 10-12 hours. Double that to 21,600 Wh by linking another set of Delta Pro and 2 Extra Batteries via either the EcoFlow Smart Home Panel or the Double Voltage Hub. Finally, this can further be expanded to 25,000 Wh through the use of a Smart Home Panel, 2 Delta Pros, 2 Extra Batteries, and 2 EcoFlow Smart Generators — a gas-powered generator that produces virtually unlimited DC output (as long as gasoline is available) for more efficient charging of the Delta Pro.

    Goal Zero can only store up to 10,871 Wh with a Yeti 6000X and 4 Yeti Tank Expansion Batteries. Let that sink in. The market leader is actually BEHIND in this area.

    EcoFlow’s Smart Home Panel can power up to 10 electrical home circuits during a blackout, the Double Voltage Hub can double the Delta Pro’s capacity with the addition of another unit, and the Smart Generator can provide gas-generated DC power to the Delta Pro for more efficient charging. Furthermore, the generator can directly be controlled by the Delta Pro so it would only be started when needed.

    Power Output

    Another area the Delta Pro shines at is what devices — and how many of them — it can power at the same time. Its AC inverter can operate at a continuous 3,600W of energy and surge up to 7,200W. If those numbers do not make sense to you, do not worry. I will go over Continuous vs Peak (Surge) in more detail later.

    1648W Charging (Overloaded Cord Reel)

    You can throw a number of high-powered devices, like a home air conditioner, refrigerator, TV, laptop, and hair dryer at it with no problem whatsoever as long as their combined power usage does not exceed 3,600W. The Continuous output can be expanded to 4,500W with X-Boost, or 7,200W by combining 2 Delta Pros with either a Smart Home Panel or Double Voltage Hub.

    Goal Zero’s flagship Yeti 6000X can only go 2,000W continuously and peak at 3,500W — numbers that were impressive and unheard of when the product was announced in 2020.

    Note: Delta Pro will shut off its AC inverter if it detects the wall plug getting overloaded when used in pass-through (UPS) mode. Only the battery’s 30A outlet can output 3,600W when disconnected from the AC wall.

    Battery Technology

    Li-ion: LiFePO4 vs NMC

    There had been a lot of debate over whether Nickel Manganese Cobalt (NMC) or Lithium Iron Phosphate (LiFePO4) was better. Both are Lithium-ion batteries. Goal Zero, Jackery, and most of today’s power station manufacturers use NMC, but why do EcoFlow and Bluetti use LiFePO4 when they are bulkier and heavier? There are important distinctions, but the best battery is the one that meets all or most of your unique needs.

    Charge Cycles

    One of the most significant differences — and buying factors — is the charge cycle count for both battery chemistries. It measures how long the battery can be used for before it must be replaced or thrown away. LiFePO4’s count is 1,500-2,000, whereas NMC is 500. However, both have a useful life that can range between 3,000 – 5,000 cycles (even as much as 7,000 with proper care). But how does the count determine longevity?

    Delta Pro: Front, Internal, Back /EcoFlow

    Let’s look at Li-ion NMC as an example. It loses about 20-25% of total capacity after every 500 charge cycle. That means after the first 500 cycles, the battery drops 20% from when it was new, then another 20% after the next 500 cycles, and 20% again after that one. It would take roughly 1,500 charging cycles to have the battery last only half as long as when it was brand-new. Thus, it should be usable for 2,000 cycles or about 6-10 years. Li-ion LiFePO4 can last longer.

    CAUTION: Lithium-ion (LiFePO4 and NMC) batteries do NOT like to remain discharged at 0% for prolonged periods of time. If you let your battery stay at 0% for too long, you may not be able to charge it again without specialized equipment. Keep them at between 20-80% while in storage to maximize their lifetime.

    LiFePO4 Advantages

    • Safer, less volatile, and thus cheaper to manufacture
    • Higher charge cycle: 1500-2000 (10 years). NMC: 500 (6-10 years)
    • Usable in more extreme temperatures (-4F/-20C to 176F/80C). NMC: only 140F/60C max
    • Holds 350-day charge. NMC: 300

    Input (Charging) Options

    Get yourself some popcorn for this. There are over a handful of ways to charge the Delta Pro, one of which provides 6,500W of input and prompted EcoFlow to claim the “World’s Fastest Charging” power station title.

    • AC
    • Wall: 1,800W (120V @ 15A) or 3,000W (240V @ 12.5A)
    • No power brick — 14AWG cord plugs directly from the wall to the battery
    • Never, ever use an extension cord to charge with! It could cause a fire or trip the circuit breaker at best
    • Charge to 100% at level 2 AC EV charging stations (with Type 1 J1772 or Type 2 Mennekes connector types) in 1.7 hours, according to the manufacturer
    • Provides up to 10 home circuits with power within 20ms of a blackout
    • Solar (XT60 port): 1,600W (11-150V @ 15A)
    • Uses MPPT that is much more efficient for charging than the older PWM technology
    • Any combination of most solar panel brands and number of panels can be used as long as their combined voltage and current do not exceed 11-150V and 15A
    • Connect up to 3 in series — or 2 sets of 3 (in series) for a total of 6 in parallel. Keep open-circuit voltage at 10-65V

    Smart Extra Battery, Smart Generator, Solar Tracker, Remote Control /EcoFlow

    • EcoFlow Smart Generator (Gas): 1,800W (up to 5,400Wh on a full tank)
    • Generator can be used standalone or with Delta Pro with included Smart Generator Adapter
    • I had asked Goal Zero and Jackery for this option for years!

    Tip: A record-breaking input of 6,500W (!) can be achieved by combining AC Solar Smart Generator charging! (A Smart Extra Battery must be connected to the Delta Pro for this to work.)

    AC Charging Speeds

    The back of the Delta Pro has a toggle for how much power it should draw for charging: Fast or Slow/Custom.

    • Fast: 1,800W (120V @ 15A) or 3,000W (240V @ 12.5A)
    • 0-80% in 2 hours and to 100% after another 45 mins
    • Slow charging is gentler on the battery, prolongs its lifetime, and minimizes risk of tripping the circuit breaker
    • Custom allows the Delta to charge at a configured rate so the wall circuit would not be overloaded. That’s an EXCELLENT feature to have!
    • Example: If an AC Circuit can only handle 1,200W and a coffee maker uses 800W, then the Delta Pro should be configured to charge at no more than 400W (1,200W – 800W)

    Tip: AC charging is prioritized over DC when both are connected simultaneously. Never use an extension cord to charge the Delta Pro with unless it’s a heavy-duty one.

    EcoFlow Delta Pro Carry Handles

    Output Options

    • (4) 20A
    • (1) NEMA 30A for RV hookup (3 prongs = 30A, 4 prongs = 50A)

    If the Delta Pro is used in pass-through UPS (uninterruptible power supply) mode, the internal circuit will turn off its inverter if it detects the AC wall outlet getting overloaded (ie. passing through more than 20A). This means that it could shut off at 1,200W without ever reaching its 3,600W capacity. To use the full 3,600W, disconnect it from the wall and let the battery provide that power.

    Note: Using a battery as a UPS (charging and outputting at the same time) could shorten its lifetime.

    • DC
    • (2) USB-A (12W max, 5V @ 2.4A)
    • (2) USB-A Fast Charge (18W max)
    • (2) USB-C (100W max, 5/9/12/15/20V @ 5A)
    • Could charge two high-powered laptops at the same time
    • A common use for this port is to connect a DC5521-to-Car Cigarette Port adapter so another car freezer, for example, could be connected
    • Anderson Power Pole (APP) port (378W max, 12.6V @ 30A)
    • Vertically configured like Goal Zero’s HPP, but in reverse
    • Connect an EcoFlow Remote Control unit via an Ethernet network cable for monitoring and controlling the Delta Pro from afar. This allows the battery to be tucked away from view

    Portable Air Conditioner

    The EcoFlow Wave is a portable air conditioner that accepts both AC and DC input. The company, of course, recommends using its own Delta power stations for better efficiency and longer runtime because they can draw directly from DC power. In a pinch, any battery or generator capable of providing the Wave-required input wattage could be used, but keep in mind that AC power loses some energy due to conversion to DC.


    • Superfast, configurable charging speeds (200W – 1,800W or up to 6,500W under specific conditions!)
    • Up to 2,000 – 3,000 cycles based on my research (I do not believe EcoFlow’s claim of lasting much longer than 6,500 cycles. Hope they prove me wrong 15-20 years from now!)
    • Much safer and stable than Li-ion NMC
    • Enough to power a typical home for days — or, when used with the EcoFlow (Gas) Smart Generator and/or set of solar panels, virtually forever
    • Pure-Sine Wave AC Inverter
    • Clean power for sensitive electronics
    • Less heat
    • Note: Some manufacturers claim to be Pure-Sine when they are actually Modified or Square Waves

    Wheels, Retractable Carry Handle

    • High-quality BMS (Battery Management System) for safety
    • Provides built-in overload, overcharge (automatic stop when the device is full), and short-circuit protection

    Tip: It is possible to get multiple companies’ products (battery power stations and solar panels) to work with one another once you understand the different connector types, such as Anderson APP, MC4, 8mm, and so on. In one test, I had simultaneously connected solar panels by Goal Zero, Jackery, Suaoki, and Paxcess to the Yeti 1500x’s Anderson port to collect energy from all four! Although I did not test this with the Delta Pro, it should work the same way.

    • Impressive input and output options, including a NEMA 30A for RV hookup
    • Up to 1,600W of solar charging
    • Competition hopefully continues to spur better products from all companies


    • Weight is due to the use of 3,600Wh of LiFePO4 battery cells instead of NMC
    • Comparison: Goal Zero, despite using a more heavy-duty, metallic enclosure, has the Yeti 3000X (3,032Wh) weigh at 70lbs, Yeti 6000X (6,071Wh) at 106 lbs
    • Even bulkier than Goal Zero’s Yeti 6000x (15.3″ x 10.1″ x 17″) that has 67% more battery capacity. Yeti 3000x is 15.3″ x 10.2″ x 13.6″
    • Cable to link Delta Pro with additional Smart Batteries is too short, limiting how and where the batteries can be placed
    • Car Cigarette Port only accepts 96W of input at 12V
    • Goal Zero Yeti X and Jackery Explorer series can take 120W (12V @ 10A)
    • Leads to landfill/environmental waste. Please recycle responsibly!
    • Most companies arrange APP horizontally
    • Can be remediated by buying an APP extension cable, such as those by iGreely, and re-arranging it


    • Without anything plugged in, the AC inverter still draws 7W on its own
    • Or, according to some companies, including Goal Zero, keep it plugged in when not in use and discharge it to 50% every 3-4 months
    • The charging controller automatically gets disabled once the battery is full
    • You may also charge it to 80% for storage, but be sure to discharge to 20% every 3-4 months
    • There is no “memory effect” in this station’s battery
    • Note: It is better to NOT let it completely drain before recharging
    • Could take 1-1.5 years to go from full to empty

    CAUTION: Lithium-ion (LiFePO4 and NMC) batteries do NOT like to remain discharged at 0% for prolonged periods of time. If you let your battery stay at 0% for too long, you may not be able to charge it again without specialized equipment.

    Continuous vs Peak Output

    Goal Zero Yeti 500x: 300W (1,200W Peak)

    It is important to understand the difference between Watts and Watt-Hours. How much power is used or produced is measured in Watts, and how much energy a battery can store is calculated in Watt-Hours. See the “Calculations” section below for more details.

    How much energy a battery can store is measured in Wh (Watt-hours), and how much power is used or produced in W (Watts).

    • AC Inverter: Converts battery (DC) power into AC
    • Delta Pro provides 3,600W continuous output with a 7,200W peak
    • Turns on OK (PEAK under 2,400W):
    • Freezer starts at 400W (peak), runs at 150W once on
    • Coffee maker starts at 1,400W (peak), runs at 800W once on
    • Home AC starts at 4,000W (peak), runs at 1,000W once on

    Most devices power on at a higher (Peak) wattage than when they are already on (Continuous). Therefore, if its peak exceeds the power station’s max, it may not be able to start

    • Continuous Output (Running): Once devices are on, as long as they keep drawing less than 3,600W total, they will stay ON until the battery runs out
    • CONTINUES running (under 3,600W)
    • 100W TV 60W laptop = 160W
    • Temporary overdrawing beyond 3,600W for a few seconds is okay. A quality BMS will protectively shut down the battery if the surge does not end after a while. Regularly going over for a prolonged time can ruin the battery in the long run
    • 300W appliance (500W peak) 1,000W Home AC (4,000W peak) 800W Coffee maker (1,400W peak) 1,200W Miter saw (2,400W peak) 400W appliance = 3,700W. Probably will stay on for a short period
    • Add 1,000W mower (1,400W peak) = 4,700W. Battery will definitely shut down

    Solar Panel – Warning

    EcoFlow 220W Bifacial Solar, Delta Pro

    This power station can be charged with one or more solar panels. There are SOME PRECAUTIONS you must take to minimize battery damage and/or injury to life/property:

    • Never exceed the maximum Voltage (V) or Amperage (A) of the power station’s charging port
    • Delta Pro limits input to 15A [Thank you, Billy Tanglewood and Kevin Lauzon for the clarification]

    Wondering what size solar panel to get? See the “Calculations” section below.

    Calculations – Size Time

    What size battery should you get? How long will it power your fridge for? How long will it take to recharge? The below calculations can help answer those questions and are rough ESTIMATES as conditions, battery quality, and age can vary.

    Time to Charge Battery

    • Calc: Hours to charge battery = Battery capacity (Wh) / Input Wattage
    • Note: As battery approaches 75% full, the input charge will increasingly be slowed down to prevent overcharging

    Charge Time with Solar

    • Calc: Hours to charge battery = Battery capacity (Wh) / (Panel Wattage x [0.5 or 0.75])
    • In a perfect lab environment, solar panels charge at the listed wattage
    • Expect to only receive 50-75% on a good, sunny day (ie. 75W – 113W for a 150W panel), depending on panel’s age, component quality, and weather
    • Keep charging even when overcast as the panels will STILL collect energy
    • Underproduction: If a 200W panel is not making enough (ie. only 50W) due to bad conditions, adding extra ones (ie. two more 200W) can generate a higher, combined output (ie. 50W 110W from the two panels = 160W total)
    • Overproduction: If the panels make more (ie. 400W) than the maximum the power station charge port can take (ie. 120W), only the max (ie. 120W) will go through

    Watts Used/Produced

    • Calc: Watts used or produced by device = Voltage x Amperage
    • Vacuum with 120V @ 9.5A uses 1,140W
    • Solar panel with 12V @ 10A can produce up to 120W

    Ideal Battery Size

    • Calc: Battery capacity (Wh) = Watts used by device x Hours needed for / 0.85
    • 10-15% of power is lost during power conversion

    How much energy a battery can store is measured in Wh (Watt-hours), and how much power is used or produced in W (Watts).

    Time Before Battery is Empty

    • Calc: Hours available for device = Battery capacity (Wh) x 0.85 / Watts used by device
    • 10-15% of power is lost during power conversion

    Time to Charge Device

    • Calc: Hours to charge device = Device’s battery capacity (Wh) / Input Wattage
    • 60W laptop with 200Wh battery: Up to 3.4 hrs (200 Wh / 60W)

    Conversion to mAh

    • Calc: Powerbank-equivalent capacity (mAh) = Battery capacity (Wh) / Voltage x 1000
    • 1 Ah = 1000 mAh

    Tips and Suggestions


    • Always test your devices with the power station before you depend on it on the go
    • Unlike NMC that is volatile, LiFePO4 (which the Delta Pro uses) is one of the safest battery technologies available today. Nonetheless…
    • To minimize fire damage to your belongings or loved ones, store the power station in the garage and not inside the house. Best storage is a dry, cool place
    • You cannot bring a battery of this capacity on a plane
    • Keep the battery out of direct sunlight. I usually store it on the floor of the car and crack open the Windows a tiny bit
    • Do not USE any power station in a tightly enclosed area as it can overheat
    • Do not USE in the car if temperatures fall below or exceed the battery’s rated, operating temperature

    Jump Start Car?

    Genius Boost GB40 in Use /NOCO

    A battery power station like this one cannot be used to jump start a car. Instead, I suggest getting a small, portable one specifically made for that, such as my favorite: NOCO Genius Boost Car Jump Starter (Lithium Battery).

    Use With Other Brands

    Nearly all of the leading power station manufacturers can be used with competing products or accessories — solar panels in particular.

    Yeti 1500x with Goal Zero, Jackery, Paxcess, Suaoki solar panels

    As long as the panels or different Watt-capacities produce the same VOLTAGE, you will be able to safely use them with the EcoFlow Delta Pro. However, be sure to NOT exceed the power station’s rated input Voltage or Amperage! All you would generally need to interconnect is to buy adapter cables that convert from MC4, 8mm, or other connector types to the Delta Pro’s APP port.

    I had previously tested my Goal Zero Yeti 1500x with the company’s own Nomad panel and those by Jackery, Paxcess, and Suaoki. It was a bliss in interconnectivity! What that means is that you can buy lower-priced solar panels that may produce the same capacity as those made by the power station’s manufacturer. You do not always have to buy their own branded products as long as the substitutes stay within the rated limits.

    Final Thoughts

    Delta Pro Package /EcoFlow

    Wow, just wow! I am so glad that my boondocking/RV friends recommended me to check out EcoFlow batteries for our vacation home. The Delta Pro opened my eyes and dropped my jaw a number of times during my research with an impressive set of features, capacities, capabilities, and integration options that rival and surpass industry leaders like Goal Zero, Jackery, and Bluetti! The list was so extensive, it took me far too long to try and collect my thoughts and research for this article.

    The Delta Pro will hopefully kick the competition in the rear, and force them to innovate and surpass EcoFlow’s latest products with their own. Competition is always good for the consumer, and I cannot wait to see what my favorite companies, Goal Zero and Jackery (and sister company, Geneverse), have cooked up in response!

    Power Station Comparison

    Check it out! Ultimate Reference: Power Station Comparison – We summarized the specifications of many of the power stations we had come across or reviewed all in one place.

    Gas/Propane Generators vs Battery Power Stations

    In July 2020, I wrote about this topic after many asked what their differences were. In short, gas/propane generators can run virtually forever but are loud, dirty, and potentially quite dangerous. Battery power stations, on the other hand, are more portable, silent, less volatile, and can be operated indoor, but depend on external power (like solar) to recharge. Where gas/propane are used to GENERATE electricity, batteries STORE them for later use. Personally, I am a fan of the latter because they are so easy to carry around and are safer to use.

    Who is EcoFlow (EF)?

    EF Delta 2 and Wave (with battery)

    EcoFlow was formed in 2017, ten years after Goal Zero had its start. Four years later saw the launch of the Delta Pro series in 2021 that garnered so much widespread attention, it earned one of Time Magazine’s “Best Inventions of 2021” under the “Sustainability” category.

    A friend of mine once said that Goal Zero is “the best of the best” because of one simple reason: their vast ecosystem. I did not understand at the time what he meant, but as I learned more about the Yeti 1500x, my eyes were opened. Then EcoFlow came along with the Delta Pro that not only matched, but managed to surpass Goal Zero in many ways with its own collection of products.

    Battery Technology and Safety

    Goal Zero debuted with Lead-Acid batteries that were bulky and heavy. Today’s devices use Lithium-ion — commonly Nickel Manganese Cobalt (NCM) or Lithium Iron Phosphate (LiFePO4 / LFP) chemistries — for more power in a smaller, lighter package. NMC, however, is more volatile than LiFePO4 and becomes riskier as more cells are packed together. Goal Zero and Jackery use NMC whereas EcoFlow and Bluetti use LiFePO4.

    • How much energy a battery can store is measured in Wh (Watt-hours), and how much power is used or produced in W (Watts)
    • The higher the Watt-hour (Wh) capacity rating, the more dangerous the battery could become if not handled right

    The quality of the battery cells and the BMS (Battery Management System) are crucial for safety.

    Cell Manufacturers

    Portable car freezer powered by Goal Zero Yeti 500x

    Battery cells made by LG and Sony are among the best in the hobbyist world as are Sanyo/Panasonic and Samsung. Goal Zero uses LG. Jackery also uses LG or BAK (a leading Chinese brand). EcoFlow makes its own. During my years of research, I found that use of lower-quality batteries could pose a serious risk to life and property and should become a crucial part in deciding what to buy.


    The second part in a battery’s safe operation depends heavily on the design and BMS (Battery Management System). Some BMS manufacturers, unfortunately, overstate their capabilities that could lead to catastrophic failure.

    • Design should allow for proper, thermal cooling, use quality components, and obtain proper certifications
    • Batteries made by known manufacturers are less likely to fail
    • BMS should sufficiently restrict the battery from going past its capabilities
