Can the EcoFlow Delta 1300 Keep the Lights on During a Power Outage. Eco delta solar generator

    Can the EcoFlow Delta 1300 Keep the Lights on During a Power Outage?

    EcoFlow began in 2017 by entrepreneurs who designed batteries for a drone company. These batteries needed to be long lasting, have high output, and be light. They took that expertise and founded EcoFlow who now make solar generators.

    The Delta 1300 is their biggest model to date. It caught people’s attention with its astounding charge claims. I am curious to see if it is a good option to run the essentials in my house if the power goes out. Let’s dive into what the Delta 1300 offers.

    Battery Capacity

    The Delta 1300 has a 1260Wh (12V) Lithium-ion battery. It is called the Delta 1300 because of the battery size. Obviously, it isn’t quite 1300, but 1260Wh is a decent battery size. The benefits of lithium-ion are numerous. They are lighter, more efficient, less maintenance, and have a longer lifespan. The battery can sit for 1 year after being fully charged and still be ready to go. That is much nicer than lead-acid batteries that required you to charge every couple of months or you would ruin the battery.


    The Delta 1300 comes in at right under 31 pounds. This puts in the easily portable category. It also comes with two carrying handles. If I am camping, hunting, road trips, etc., I want something I can pick up easily and not break my back doing it. It’s also nice if my wife can pick it up if I wasn’t there. I’m really happy with the weight of this system.

    Charge Speed

    The charge speed on the Delta 1300 is what really caused a wave in the solar generator industry. They claimed that with a wall charger you could charge from 0% to 80% in one hour! It can be fully charged in 1.6 hours. That is 10 times faster than competing units. For example, if you look at the Goal Zero Yeti 1400. it takes 25 hours to charge from a wall outlet. It blows it out of the water.

    Because of how fast it charges, it does have its own issues. To charge that fast, it creates a lot of heat. Heat creates inefficiencies in electrical units, and because of the heat the Delta 1300 requires a lot of fans to try to cool it down. It also has to cool down between charging it and using it again.

    How does it do with solar panels? It allows up to 400W of solar input. Now, if you watch my video you know that I was able to put 600W of solar panels into it and it worked fine. The fastest charge speed you will get from solar would be about 3.25 hours. That is fairly good, and is under the 5-6 hour per day window I want to be in. That means I should be able to run something during the day and still charge it back up.


    The ability to expand the battery capacity on a solar system is important to me. I like the option of being able to expand the capacity of my system to meet my needs, especially when I consider how much money I spent. The Delta 1300 doesn’t have a typical battery expansion option, unlike the Titan or even the Goal Zero Yeti line. But what you can do with the Delta 1300 is chain another Delta 1300 to it. You can have up to 6 Delta 1300s linked together, giving you a combined battery capacity of 7560Wh. That is a lot, but I don’t like that you have to buy a whole Delta 1300 instead of a cheaper battery only option. There is no option to expand the solar panel capacity, although I was able to get 600W panels instead of the 400W that is listed.

    Life Cycle

    A lot of solar generators in this size have 500 life cycles before the battery starts to degrade. A life cycle is from 100% to 0% and then charged back up to 100%. Once 500 cycles are reached, it doesn’t mean the battery is worthless. Typically, they are good for about 80% after that. Meaning if you had a 1000Wh battery, after 500 cycles it would only be rated for 800Wh.

    The Delta 1300 is rated for 800 cycles. Better than the typical 500, but something interesting is that after those 800 cycles the battery drops to 60% capacity instead of 80%. That reduces the battery capacity to 1260Wh x 0.6 = 756Wh.

    I think it only has 500 cycles like many other units before it reaches 80% capacity. But they rate it to 800 cycles to look better and don’t really tell anyone that it will be 60% efficient by then, rather than 80% efficient at 500 cycles.

    Number of Plugin Ports

    There is a total of 13 output plugs on the Delta 1300. There are 2 USB-A plugs, 2 USB-A fast charge plugs, 2 USB-C plugs, a 12V car plug, and 6 AC plugs. I like the layout of the USB plugs and the screen display. It is simple and clean looking and works very well for smaller appliances like phones and laptops. The screen shows both input and output watts, a percentage battery display and a total run time counter.

    On the opposite side are the 6 AC plugs. They are so close to being spaced out well enough that they don’t hit each other, but unfortunately, I think they are a little too close. Although I was able to get 6 plugs in, they were pushing on each other. If I used a boxier plug or a box plug, it covered up the one next to it making it unusable. They also only allow 3 of the 6 to be plugs with a ground on them. If you had 6 plugs that all had grounds attached, you wouldn’t be able to plug them all in.

    Inverter Size

    The Delta 1300 uses a Pure Sine Wave inverter with 1800W continuous usage and a 3300W surge capability. It’s pretty typical for the surge capacity to be double that of the continuous watt rating, but in this case, it is a little less than double.

    I’ve noticed with some solar generators that if the inverter is mismatched from the battery, it can’t pull the full continuous watts that it is rated for. I don’t like paying for a more expensive inverter if it’s limited by the size of the battery. During my testing of the Delta 1300, it was able to pull 1800W continuously. Of course, that drained the battery in under an hour, but it’s good to know that it can do it. It should be noted that when you discharge the battery that fast, it does need to cool down for a while before it can be charged back up.

    RV Connectivity

    Unfortunately, there is no RV port. I think the size of this unit would be really well suited for RVers, so it’s too bad they didn’t incorporate a RV port into it. It makes it so much simpler.

    For RVers who want to run their campers/RVs without the A/C unit I think this is a good option.

    Car Charging Capability

    It does come with car charging capability, charger included. It will take a car about 10 hours to recharge. This is a must for me if I’m looking for something to take camping or on road trips. Let’s do some quick math here. 1260W/10H = 126W. So, if your car charger is inputting a 126W, and let’s say you have a DC fridge that used 30W, then you could be running your fridge and charging at 96Wh/hr.

    EcoFlow advertises a 130w charging speed. When I ran mine it was getting 129W, so I’d say that’s accurate.

    Customer Support and Warranty

    EcoFlow warranties the Delta 1300 for 2 years. I always tell people to use their solar generator a lot at first, because if there are going to be issues you want to find out while it is under warranty. 2 years is a generous time frame, and it seems a lot of companies are bumping it up from 1 year.

    That being said, there are multiple people having issues with EcoFlow’s customer support. I personally have not had any major issues with mine that require any warranty help. That doesn’t take away from the fact that many people have mentioned they have difficulties getting ahold of EcoFlow.

    Full-Sized Kit

    In order to have everything necessary to have the full kit you will have to get extra items that do not come with the EcoFlow Delta 1300. The following items are what is suggested from all of my testing:

    Final Thoughts

    After using the Delta 1300 at my house, my cabin, and on the road, here are my final thoughts. It has crazy impressive charge times for wall charging, but it comes at a cost. Not in money but in battery performance down the road.

    The price point is great, coming in at around 1400 without solar panels. That is well below similar models like the Bluetti EB240 or the Goal Zero Yeti 1400.

    But to answer my original question, will it power my house if the power goes out? I don’t think so. It is really close, and it could certainly run the bare essentials for a while. I don’t see it being able to run them continuously though for multiple days in a row. It’s just cutting things way too close, and I would need perfect sunlight to get charged up again while running my appliances. But because of how fast it charges, and its price point, I think it is a really good option for weekend camping, road trips, Vanlifers, etc. Depending on your application the EcoFlow Delta 1300 is a go in my book.

    EcoFlow DELTA mini Portable Power Station Review

    The EcoFlow DELTA mini is a 1400W Portable Power Station that has the ability to fast-charge with rates up to 900W, as well as charge and supply power at the same time. Paired with up to 300W of solar panels, it can operate demanding loads off grid, or top off quickly from AC power no matter the situation. With an 882Wh battery, the DELTA mini is anything but, putting it into a market segment few can compete against it.

    The EcoFlow DELTA mini is a 1400W Portable Power Station that has the ability to fast-charge with rates up to 900W, as well as charge and supply power at the same time. Paired with up to 300W of solar panels, it can operate demanding loads off grid, or top off quickly from AC power no matter the situation. With an 882Wh battery, the DELTA mini is anything but, putting it into a market segment few can compete against it.

    The Portable Power Station market has seen plenty of entries over the past few years, each looking to cover different segments of the market. These use cases generally include off-grid, emergency backup or camping, all areas where a power outlet is needed but source may not be available. Beyond a large inverter or a big internal battery, many of these units try to set themselves apart from the pack through cost or features. Charging capabilities are a huge differentiator, where AC input is most common, followed by car power and solar.

    EcoFlow DELTA mini

    The EcoFlow DELTA mini is a 1400W Portable Power Station with a battery capacity of 882Wh. It supports peak power draws up to 2100W, and also has an X-boost mode for certain power-hungry devices that are less sensitive to power quality that increases the 1400W capabilities up to 1800W. This puts its power capabilities closer to that of a gas generator than most rechargeable systems on the market.

    Another key aspect of the DELTA mini is its ability to charge at up to 900 watts when connected to AC power, which allows it to fully charge in under 2 hours. This might not seem like much, but some models can take most of a day to charge with much smaller external power supplies. The DELTA mini can also support power while operating, giving it UPS capabilities or keeping devices running while your car or solar panels are adding juice back into the battery. If you are running equipment and low on power, you don’t need to turn things off to charge the battery.

    Out of the box, the EcoFlow DELTA mini comes out as a very slick and fully integrated power solution. It has a very well-made case with a study feel. Minimal plastic creaking when you move it around and it also has integrated rubber pads on the bottom of the case to give it a solid footing. Design can go a long way and EcoFlow really went all out, building the DELTA mini with a premium look and feel.

    The front of the DELTA mini has a bright and easy-to-read display, giving you a concentrated view of the inner workings of the Power Station. Left to right with a quick glance you can view runtime remaining, charge percentage of the battery, incoming and outgoing power usage as well as some other indicators showing you which ports or features are active.

    The continuously updated runtime indicator is very useful, giving you real-time feedback on how loads are affecting the battery. Battery capacity gives you the vital stat of how charged the system is, and then incoming and ongoing power let you track usable and charging capabilities.

    There are only two buttons on the front of the case, a big yellow on/off button as well as an IoT reset button. On and off is pretty obvious, while the IoT button allows you to configure remote access. The DELTA mini has a feature-rich app that really makes it stand out from other models on the market, which we will get into shortly. Finally, the front includes a USB-C port, two USB A ports and a fast-charge USB-A port.

    On the back of the sides of the DELTA mini are fan vents, which are used for the Power Stations’ thermal management. These kick on dynamically during heavier power draws, as well as during the fast charging modes. They quickly spin down as demands decrease, so there are many times when the fans are perfectly silent.

    On the back are the main charging inputs as well as the higher-watt DC outputs. On the top, there is a little pop-up cover to hide the inputs during deployments. Under the cover is a DC jack for car or solar charging, a charge-rate selection switch, an AC input plug and a circuit breaker. With most Power Stations on the market including an external power adapter, the fully integrated power supply is a really nice touch. It makes sense though as many of these power adapters get very warm during charging. The 900W charge mode leverages the internal fans to keep both the battery and that integrated power cool.

    From a port layout, EcoFlow gives the DELTA mini 5 120V AC outlets, four of which have a cutout to allow three-prong devices to operate ungrounded. It also has a covered car power jack and two DC ports. Both AC and DC output segments can be switched on or off separately, while the USB ports on the front are always on.

    EcoFlow DELTA mini App Remote Management

    EcoFlow offers extensive remote management capabilities for their compatible devices, spanning from RIVER and DELTA series Power Stations to Smart Home Panels and Smart Generators. The app provides a centralized way to monitor and control your device, no matter if you are 5 feet from it or miles away. It does that through its own Wi-Fi hotspot or connecting to a known wireless network in range. From that, it interfaces locally or remotely through EcoFlow’s Cloud platform.

    The EcoFlow app is pretty straightforward, with both iOS and Android versions. Once you register an account with EcoFlow you hit a screen allowing you to add in different EcoFlow models you have. Clicking the “” symbol brings you to a screen to add in different models in their portfolio, with instructions then given on how to connect them. For the DELTA mini, you press the IoT reset button on the front of the device and then connect to the EcoFlow Wi-Fi network it stands up. Once connected, you can then interface with the Power Station.

    The remote interface shown for the DELTA mini is very intuitive and continues the trend where EcoFlow put a lot of thought into each design element. The landing page shows the main vitals of the Power Station, with an overlay on top of the model’s rendering showing you the current capacity.

    At the top, you see the operating temperature of the device, estimated runtime and current battery capacity. The next section splits into two parts covering input and output. Output is the default view, showing you a real-time view of the watts consumed across the AC, 12V DC and USB ports on the mini. Both the AC and DC parts can be remotely switched through the app, allowing you to disconnect loads even if you aren’t standing next to it. You can also manually enable X-Boost mode for higher AC loads (although not as compatible with all devices).

    The input side is more basic but focuses on the power supplied by either DC sources (Solar and automotive) or AC. They also give a real-time moving chart of the current incoming or outgoing load, although it starts from scratch if you switch views or exit and re-enter the app view. A historical view would be nice, although honestly, it’s still impressive to have this much monitoring presented from the system regardless.

    The settings area is equally impressive, opening more functionality that will be appreciated by those using the DELTA mini on a more regular basis. For increasing longevity, or just not wanting to deplete the unit out in the field, EcoFlow lets you set the discharge and charge percentage levels. By default, this is 0 to 100%, but you can tighten that up to narrow the charge cycles for increased battery longevity. Bumping up the discharge from 0% also lets you set a built-in reserve.

    Next are the AC and DC charge settings. While the physical switch on the back of the unit lets you change between the default 200W and 900W fast charge modes, if you keep the switch set to the 200W mode, you can adjust the peak charge rate to a custom level inside the app. You can adjust it from 200 to 900W in 100W increments, which is useful if you want to balance loads from the Power Station versus other devices on the circuit. An example might be fast charging multiple DELTA mini’s on the same circuit, without worrying about tripping the breaker. You are also given a similar setting for the car input, which is adjustable from 4A to 8A also in 1A increments.

    The app also gives you traditional customization options like disabling the beeps during mode switching, unit and screen timeout, as well as AC plug timeout. For a remote excursion, you might not want the AC ports staying on if you accidentally forget to switch them off. For a home office UPS use case though you would want to leave the AC ports on always. You can also view and update firmware through the app, which is handy to keep things current in terms of lifecycle management.

    Finally, EcoFlow gives you a Specifications view, which is quite useful. Not everyone memorizes the capabilities of their electrical equipment, so having a reference guide can come in handy. Here you can find all the details for the DELTA mini, and probably similar views for other models in their portfolio. Highlights include the serial number for support, rated capacity, device weight, storage and operating temperature ranges, and all of the input/output ratings. Being able to cross-reference the output capabilities without needing to break out the instruction manual in the field could be invaluable to some.

    EcoFlow 220W Bifacial Solar Panel

    EcoFlow also supplied their new 220W Bifacial solar panel with the DELTA mini, which has an interesting element to help drive more flexibility for a Portable Power Station. As the name implies, the design is Bifacial, which in simple terms means it can absorb light from both sides.

    The front side offers 100% of its 220W rating, the rear is rated for 155W. Now, this doesn’t mean you add both sides together for something greater than 220W, instead, the front absorbs the bulk of the power, and the rear when propped up captures some of what is reflected off the ground, a bit of a solar bonus.

    EcoFlow gives some examples of reflectivity of different surfaces and even claims if you set up mirrors behind the panel you can get up to 80% more power than you’d otherwise be able to capture. For real-world conditions most probably won’t be setting up mirrors, but it does go beyond what you’d normally find from a traditional solar panel.

    The manual also states that if the sun is overhead, you will still get the most power from laying the panel flat on the ground. The rear-side absorption is really from different parts of the day where the sun is coming in from steeper angles where you are trying to get every last watt of power into the battery.

    For reference, here’s the energy reflected off common surfaces:

    Both the EcoFlow Solar panel and DELTA mini are compatible with a wide range of other devices, there’s no platform lock-in here. You can connect the DELTA mini to most solar panels with MC4 outputs that fall within the supported voltage ranges and the solar panel has those same universal MC4 connectors that make it work with 3rd party Power Stations.

    During our use with the 220W Bifacial Solar Panel, we saw strong performance even during partly cloudy conditions. With a slightly overcast sky, we saw between 70 and 160W as clouds partially blocked the sun. On a bright day without overhead clouds, those rates jumped to 170-180W. The interesting element was tilting forward the solar panel off the ground though, increasing the power output by 10-20W.

    The strength of the DELTA mini paired with a high-performing solar panel is that you can charge the battery while also supplying power at the same time. During our testing, we leveraged this capability to keep the DELTA mini topped off while also providing power to a smaller 125W load over the AC inverter. The unit operated on a net-positive charge rate, where we were supplying our power and adding to the charge at the same time. Solar is a field with many variables, so actual results can differ. But it’s incredibly useful to keep operations going while charging the portable power station at the same time.

    EcoFlow DELTA mini Field Use

    Having power on tap in any situation is a valuable asset, which is why this Portable Power Station market is growing as fast as it is. The DELTA mini offers 1400W of power (2100W peak) under normal usage giving you a lot of power without compromises. To put this in comparison, most household devices are designed around a 1400-1500W peak limit to fit the 15A breaker size found in most homes and businesses. This puts the DELTA mini in the sweet spot of covering most items that can connect into a common plug, and many bigger draw items that don’t care about power quality when running in X-Boost 1800W mode.

    In an IT setting, having power on hand even for mobile devices is an important role. Many workstation-class notebooks draw power at a fast pace and running off its battery can have limits on CPU and GPU performance. Connecting to a power source for short to intermediate usage can help get the job done faster or keep systems going that would otherwise drain rapidly on internal batteries. Then pile on non-battery-powered accessory devices like networking switches, shared storage devices for collaboration, or even external monitors where an external AC power source becomes a requirement to keep things running.

    One example of the slightly larger DELTA being used in the field is from our resident Digital Imaging Technician, Vince Carnevale. He uses it to get workstations and monitor carts up and running while filming on-location before the electric department can provide generator power. Used in connection with a UPS, the DELTA provides a few hours of runtime, giving DITs and the cinematographer the ability to get to work right away.

    The UPS is still leveraged in this situation since the equipment they are operating has power-loss tolerances less than 30ms, which is the switchover time the DELTA series can react with. The UPS gives the sensitive equipment its needed buffer, while the EcoFlow DELTA offers the bulk power source for the cart. With the fast charge time, once power becomes available the DELTA is able to quickly recover its charge capacity to get ready for the next occurrence.

    In edge IT deployments standing up equipment for initial configuration may mean supplying your own power for a while. Here the DELTA mini can be leveraged to get servers operational for a period of time before you get them wired into their final production environment. We tested the DELTA mini with the 3-node Supermicro Edge IoT server, which had no problem standing it up in our lab.

    ecoflow, delta, 1300, keep

    In the field you might need to power it up say inside your truck, and confirm settings are correct before finalizing your deployment. The mini wouldn’t be the permanent power source, but instead, one that gives you 30-60 minutes of runtime to perform specific tasks before the final installation.

    Final Thoughts

    In the Portable Power Station market, EcoFlow has shown some serious strength with the DELTA mini and their broader portfolio. It hits all the right buttons, covering a large capacity, powerful inverter, onboard fast charger, and an impressive remote management platform.

    While the mini is the smallest unit in the DELTA series, EcoFlow scales up to a huge ecosystem covering large power stations, solar panels, and associated equipment. For the smaller shop looking to stand up hardware in the field or the media professional getting ready for a shoot, EcoFlow has carved out a niche for themselves with the DELTA series.

    Let’s just say it; gas generators are not ideal for home backup. They’re loud, toxic, expensive to run, and they will soon be illegal in California!

    The EcoFlow Delta Pro has marketed itself as the best portable power station for home backup, but do the claims live up to reality? That’s what we’re going to test today.

    For the sake of this experiment, let’s say that you don’t have a spare battery and you only have one 400W solar panel working at 50% capacity (due to the storm). Let’s see how it does!

    EcoFlow Delta Pro Battery Life and Input

    Before we start, let’s understand how much power we’re dealing with. A full charge can safely last on your shelf for over a year, offering a base capacity of 3600Wh. If you’re expecting this to decline like most batteries, understand that the EcoFlow Delta Pro batteries will last 6500 lifecycles before declining 20% from their original capacity.

    On top of that, if you are receiving 200W of solar energy for 14 hours of the day, then that’s an additional 2600Wh to 2800Wh on your system each day, as the system works at around 94% efficiency, which is higher than any other portable power station on the market. Let’s call it 2700Wh for the sake of simplicity.

    Of course, if you have an additional Smart Battery or more solar panels, then you will significantly increase your power output and you can read our full review of the system for more information. However, if you want to save money on the upfront costs, then here’s what to expect.

    How Long Will It Last for Home Backup

    Now that you know the performance of the EcoFlow Delta Pro, it’s time to put it to the test. Let’s see how long a 3600kWh system can last with an extra 2700Wh per day!

    With Conservative Energy Consumption

    Let’s say you have plenty of ice packs in the freezer to keep everything cool for a couple of days without power. All you need is to charge your family’s iPhones, run a few LED lightbulbs, and keep a television on for a few hours of the day.

    If you’re charging four 10W LED lightbulbs, one full charge will last 84 hours without solar panels, so you’d also be able to charge your iPhone as many times as you’d like with the ongoing power from the solar panels. A 50-inch TV (110W) could stay on for at least 10 hours a day on top of that, and 5 or 6 hours with TV and internet so you can watch your favorite streaming service!

    If you’re using a hotspot on your phone and limiting your energy use during the night without offsets, this type of lifestyle could last indefinitely.

    With Moderate Energy Consumption

    A power outage doesn’t have to be too much of a bummer. If you limit your energy consumption, you can potentially power a lot. In this case, let’s say you want to:

    • Keep your refrigerator running
    • Run 10 LED lightbulbs
    • Keep your iPhone charged
    • Run a 110W television

    The refrigerator is the bulk of the energy consumption in this case. One full charge from your EcoFlow Delta Pro will only last 24 hours for a large 120W refrigerator, so the 200W solar offset will certainly help.

    At night, you would have to dramatically reduce your energy consumption to allow the refrigerator to run. In this case, we’d recommend limiting television use to daytime and to limit use to 3 hours or less. If you don’t allow the system to fully charge by sunset, then the refrigerator may not stay on through the night.

    However, a couple of hours will not be the end of the world for the food in your refrigerator or freezer, especially if you don’t open it before turning it back on. For that reason, this lifestyle is plausible for one EcoFlow Delta Pro portable power station and solar panel to last for 3 to 5 days.

    With Heavy Energy Consumption

    Here’s where we run into some trouble. If you don’t want to (or can’t) make any sacrifices during a power outage, then understand that the average home uses 28.9kWh per day. If you want to continue using such high amounts of electricity by running incandescent lightbulbs, refrigerators, televisions, heaters, Wi-Fi, and more, then you will need more power.

    Fortunately, the EcoFlow Delta Pro can potentially help you if you purchase the right bundle deals. With a maximum input of 1600W (continuous), you could easily run the majority of your appliances at home, especially with a spare battery to last through the night.

    Keep Them Running

    Now that you see why the EcoFlow Delta Pro is the top choice for home backup, consider getting one for yourself and putting your gas generator to rest. 3600Wh goes a long way when you have solar panels to assist, and best of all, solar energy is free!

    What are my options for adding additional batteries and Solar Panels to the EcoFlow Delta Pro?

    Adding an EcoFlow Delta Pro expansion battery can be a great option if you need more uninterrupted power. When you add an expansion battery to one of the delta pro units they automatically act as one unit together, which makes for a super easy expansion for your off-grid power. Depending on your energy usage, whether you are wanting to run your power tools, heavy-duty appliances or just need a complete power solution you may want to add an extra battery to your delta pro ecosystem.

    You can add up to two expansion batteries to your EcoFlow Delta Pro for ultimate power security. Without using solar power as an energy source, two fully charged expansion batteries could power a fridge for two days or a circular saw for five hours straight. If you then attach your solar panels to your EcoFlow Delta Pro System, you should be able to run some of your heavy-duty devices uninterrupted to keep you going for all of your Home Backup Needs.

    What is the Solar Input for the EcoFlow Delta Pro?

    The EcoFlow Delta Pro is the only portable generator that allows for up to 1600W of solar input at a time. You can charge the 3.6 kWh battery in just over 2 hours with enough solar panels.

    Also, with its 3600W output (7200W surge), you can easily run your system indefinitely with 1600W of continuous solar input, now that is Smart energy management! This is more than enough for your backup power needs so you can power a refrigerator, air conditioners, or other large appliance. Incredibly impressive and efficient portable power technology!

    How fast will the EcoFlow Delta Pro Charge so I can get ready before a power outage hits?

    You can be fully charged in 1.8 Hours! EcoFlow‘s battery management system guarantees longevity and safety while you fully charge your EcoFlow DELTA Pro from a regular AC wall outlet in 1.8 hours. Ecoflow’s x-stream charging technology isn’t just fast, it’s safe too. Definitely the gold standard in charging capabilities.

    What can I use my EcoFlow Delta Pro for aside from emergency power backup?

    The EcoFlow Delta Pro is one of the most incredibly versatile Smart generators on the market. Feel at ease knowing you have an energy backup incase of an emergency, you can bring it along for outdoor adventures (it has wheels for ultimate portability!), rv road trips, or you could even use it to lower energy bills for regular use at home!

    If this is your first time using an EcoFlow Delta Pro, just know that it is incredibly simple to set up and use and here at Wild Oak Trail, we are more than happy to answer any questions you might have!
