CleanTechnica Tested: EcoFlow DELTA 2 Portable Power Station
EcoFlow has been a pillar of the portable power station market for years now and they are showing no signs of slowing down. The new EcoFlow DELTA 2 bundles EcoFlow’s robust iron phosphate battery cell tech with its proven power electronics into a compact 1,024 Wh / 1 kWh package that boasts an impressive 1,800 watt continuous / 2,700 watt peak power output. EcoFlow sent us the new DELTA 2 portable power station to run through the paces and we eagerly got to work.
Right out of the box, the first thing that stands out is the price. 999 for a solid portable power station from a proven company like EcoFlow with even better to be had during the launch week. That price gets you a full kilowatt-hour of storage capacity using iron phosphate (LFP) cells that enable far more cycles before the pack capacity starts to degrade. The DELTA 2 should still have 80% of its storage capacity after 3,000 cycles. Said another way, if you cycled the battery fully every single day, you could do that for more than 8 years and still have 80% of the boilerplate storage capacity.

The trade off for using LFP cells is typically a heavier and larger pack, but the DELTA 2 comes in a svelte, compact package. EcoFlow has included handles on either side of the unit that make it easy to move around its 27 pound mass. I found it to be one of the most ergonomically friendly, easy to move packs I’ve tested. If you’re not planning to move it around, the handles make great anchor points to secure it into your RV, trunk, boat, etc.
Real World Testing
The recent California heat waves presented an opportunity to use the DELTA 2 to manually load shift electrical usage from off peak to peak usage times. Over the course of the week-long heat-induced grid strain, the DELTA 2 made it easy to plug it in in the morning and using it to power the entertainment system for a few hours in the evening. It was more than up to the task of powering a 65″ TV, networking switch, PS5, Raspberry pi and supporting gear as they only pulled between 170 and 300 watts combined.
The DELTA 2 supported this setup for the full 5 hours almost every night with no issues. It’s a beautiful use case for the DELTA 2 and replicates the use case in a recreational vehicle or off-grid home, where the power station would be charged up again from a row of solar panels on the roof of the vehicle the next morning. With a 200 watt solar panel pushing power in, testing showed that the EcoFlow DELTA 2 would recharge in 5-10 hours here in Southern California depending on the angle of the panels.
On Labor Day, the DELTA 2 made it easy to take the party outside, powering a single burner induction cooktop to fry up some home made egg rolls. Cranking on the induction cooktop, the power pack immediately woke up and started pushing out power to support the hefty load. On the medium high temperature setting, the DELTA 2’s display showed in real time how the induction cooktop pulses the full power on and off in order to lower the average heat delivered. With a cast iron pan, the egg rolls didn’t seem to mind one bit.
It was the perfect way to get the family out of the house for a COVID-friendly gathering, keep the extra heat out of the house, and shift some load away from peak hours to keep the fragile California electric grid running. A few dozen home made crispy egg rolls later and the DELTA 2 hardly blinked as it pushed out 1,500 watts almost constantly for nearly 45 minutes.
With the DELTA 2 plugged into a wall outlet, it immediately woke up and started drinking power, gulping down 1,170 watts from the outlet. That translated to a full charge in just under an hour. Pulling 1,100 watts from a wall outlet isn’t the fastest we’ve seen, as some units can pull up to 1,800 watts, but the ability to fully charge from a wall outlet in under an hour should meet the needs of most consumers. EcoFlow says it will recharge from 0 to 80% in just 50 minutes or from 0 to 100% in 80% which makes the DELTA 2 a great addition when the use case requires maximum flexibility.
We took the DELTA 2 outside and connected it up to EcoFlow’s high power 400 watt portable solar panels and it eagerly soaked up the power. It is rated to pull up to 500 watts from solar panels (11-60V, 15A) so this was no surprise. We set the panels up at 9am at our Southern California testing location and were able to fully charge the DELTA 2 in 3 hours without having to move the panels. That demonstrates the impressive power output of EcoFlow’s folding 400W solar kit and the ability of the DELTA 2 to charge up quickly with an appropriately sized solar system.

For those looking for flexibility when it comes to the capacity, the DELTA 2 has you covered there as well. A special expansion port on the side of the unit allows for the addition of one of the two available external battery packs to the unit. Connecting the DELTA 2 Extra Battery adds one kilowatt-hour of capacity (2kWh total) or you can go big and connect a 2kWh DELTA Max Extra Battery for a total of 3kWh. The additional packs are also nice in that they open up different installation options and more flexible configurations.
The DELTA 2’s 1kWh capacity makes it a solid choice for intermittent home backup power. Here in Southern California, the grid regularly cuts out and the DELTA 2 is more than up to the task to keep the lights on, the refrigerator humming, and the internet running. Adding a folding or stationary solar panel further extends that functionality and could keep the essentials running for much longer when the sun is shining.
As a mobile power station, the DELTA 2 can effectively replace a complete power system in an RV. It directly replaces the battery pack, an 1,800 watt inverter with AC and DC output, and allows for direct charging from solar. The ability to add more storage capacity means the system can even scale up or down to accommodate larger vehicles and more appliances.
The possibilities are really endless. The DELTA 2 is so capable and flexible, it’s an easier task to imagine what it can’t do than to list out all the things it could be used for, but just to get your mind going, here are just a few of the many scenarios the DELTA 2 comes in handy:
- Keep your food cool in a portable electric cooler at a soccer game
- Store and discharge power for an off-grid home
- Keep the internet running and the lights on at work when the grid goes down
- Make breakfast at the beach after a killer morning surf session
- Replace Propane, lead acid batteries, charge controllers, and inverters as the power system for an RV
- Charge all your devices while camping off-grid for a week
- Store power for your home in the event of an unplanned grid outage

Review: EcoFlow DELTA 2 Portable Power Station
Improvements in portable power stations have been pretty drastic recently, with various capacities and output capabilities. You don’t have to settle for a single power station because many can fit your budget and powering needs. Also, at this point, power stations are now using LFP batteries, which means Lithium Iron Phosphate, which can give many more charge cycles, ultimately making it much more worth purchasing a power station.
In this review, we’re looking at this EcoFlow DELTA 2 power station. This is a successor to the original DELTA from EcoFlow, but this one has a few upgrades; one of the most notable being that the DELTA 2 uses LFP batteries that will give it a longer life. Let’s take a closer look at what else this power station features and why this may be the only power station you’ll need for the foreseeable future.
So the DELTA 2 has a 1,024Wh capacity, slightly lower than the original DELTA, which has a capacity of 1,260Wh. Is this that big of a deal? No, we don’t think so because remember that DELTA 2 uses LFP batteries. This battery has 3,000 charge cycles, and even after that many charge cycles, you can still retain 80% or more of its original capacity.
On the other hand, the original DELTA uses Lithium-Ion batteries, and after just 500 charge cycles, it will have 80% or possibly more of its actual capacity. The use of LFP batteries is far more critical than the slightly lower capacity on the DELTA 2. You’ll ultimately get similar usage times with either version of the power station when it comes to charging devices or powering appliances.
When charging devices such as phones using this DELTA 2, you can charge most phones to full power about a hundred times. Charging tablets or laptops with similarly large batteries will be able to charge to their full power twenty times from the EcoFlow DELTA 2. Overall, charging devices with a power station is no different here, and if all you’re using is charging devices from this unit, then you’re looking at practically weeks of reliability.
Powering appliances with DELTA 2 is excellent because of the unit’s high output, but we have to say that the 1,024Wh capacity is somewhat of a mismatch. Usually, power stations have a matching capacity and output, but that’s not the case here. If you power a 1,000W appliance, you can use the power station for 1 hour, while using a 1W appliance will have this power station last 1,024 hours.
Since the DELTA 2 has a 1800W max continuous output, if you were to power a 1800W appliance, you’d be able to use the DELTA 2 continuously for about 40 minutes. With the X-Boost feature activated, you can use up to 2200W, and an appliance using 2200W will last about 25 minutes.
Yes, it can sound limiting, but even if you’re using high-wattage power tools that are being used intermittently, you can still use this power station for a decent amount of time. To consider how fast the battery can drain with a high-wattage appliance, we plugged a deep fryer into the DELTA 2, set it to 350 degrees, and turned it on. The battery was at 100%, and the fryer pulled 1754W. Once the fryer hit an oil temperature of 350 degrees, it turned off, and the battery was at 47%, which took 11 minutes.
EcoFlow has considered the battery capacity of the DELTA 2, which is why a new feature they added is the ability to connect an extra battery to the DELTA 2 power station. You choose between the DELTA 2 Extra Battery which can give you a total of 2kWh (2048Wh) extra battery power, or the DELTA Max battery, which will give you a larger 3kWh (3040Wh) capacity that can be connected to the port off to the side of the DELTA 2 power station.
The output options and their power are not lacking; the EcoFlow DELTA 2 delivers excellent power with each section. The sections on this unit include the USB ports, the DC ports, and the AC Outlets.
The charging port section has two USB-C Power Delivery ports, two USB-A Quick Charge ports, and two standard USB-A ports. The two USB-A Quick Charge ports have an 18W output, and the two standard USB-A ports each have a 12W output.
The two USB-A Power Delivery ports each have a 100W output. Charging power is top tier from the DELTA 2, easily one of the best charging port setups we’ve seen. Power stations from other brands tend almost always to have USB-C PD ports lower than 100W, and some don’t even have Quick Charge ports, the inclusion of not one but two USB-C PD ports makes us feel like we’re dealing with a premium brand.
In our case, we tested all the ports by charging from each simultaneously. We plugged an LG G7 and a Galaxy A51 into the USB-A Quick Charge ports, and both phones could fast charge. We plugged in a Galaxy S6 and a Google Pixel to the standard 12W USB-A ports, and the Galaxy S6 was standard Charging, while the Pixel was somehow able to rapidly charge despite charging from a standard port.
We charged a Galaxy Note 9 from one of the USB-C ports and a Lenovo Flex 5 from the other USB-C port; the Note 9 was able to fast charge, and the Lenovo laptop was able to charge at its max speed. So, just a quick overview, four phones could fast charge, and a laptop could fast charge simultaneously, resulting in an output of about 65W to 70W.
You can easily charge two USB-C chargeable laptops if needed because a 100W PD output can charge nearly all USB-C laptops. The Charging from the DELTA 2 is an absolute win.
The DC section includes two DC 5521 ports and one cigarette lighter port. This will likely be the least used section on this power station, just as with other power stations, simply because most consumers don’t have appliances or devices that are charged or powered from these ports. You can still find a use for them, as we did. We used a portable tire pump with a cigarette lighter port.
There are six AC outlets on the DELTA 2 power station, four of which are two-prong outlets and two three-prong outlets. As mentioned in the power capacity section, this power station has a 1800W continuous Pure Sine Wave output, which can be raised to 2200W using the X-Boost feature in the EcoFlow app for Android and iOS devices.
You can power most appliances using the DELTA 2, which is a surprise because battery capacity and output usually match a power station. That’s not the case here, which is why you do have to know what type of runtime you’re getting.
As we mentioned, the first appliance we tried with the DELTA 2 power station was a deep fryer that we set to 350 degrees. While heating up, the deep fryer pulled about 1755W from the power station, an insanely high output at the cusp of the 1800W max output of the DELTA 2. The deep fryer ran without any problems and reached the set 350-degree temperature.
We then plugged a Lasko heater into the power station, set it to low first, and used 800W; we then set the heater to high, and the power station was outputting 1400W. In both settings, the heater ran great, and the ability to power a heater is incredible for those fall and winter months.
That said, It’s best to stick to a low setting for heaters when using this DELTA 2 power station because even though it’s capable of powering the heater at high, doing so will make the power station only last about 40 minutes. When we ran the Lasko heater on low, the runtime would be about 1 hour and 20 minutes.

Recharging the DELTA 2 Power Station
Recharging the EcoFlow DELTA 2 is just as good as the output, mainly because of the AC recharging speed, which is 1200W. This power station doesn’t use a charging brick; instead, you get an AC charging cable in the box that plugs into the wall, and the other end connects directly to the power station’s AC input. With a 1200W input, this unit can recharge from 0% to 80% in about 50 minutes. This incredible recharge speed is becoming the norm among power stations as you can get back to using your power station much faster.
The 1200W recharge rate may cause some concern regarding its effect on the battery. Still, because the DELTA 2 uses an LFP battery that is less volatile, charge cycles are not nearly as affected as Lithium-Ion batteries.
Also, suppose you are concerned about the 1200W input. In that case, you can use the EcoFlow app to adjust the recharge speed to 200W, and this feature can also be useful to quiet down the fan because the internal fan of the DELTA 2 is pretty loud when the unit is recharging at 1200W.

Size and Weight
Considering the output and the capacity, the Ecoflow DELTA 2 is on the smaller and lightweight side. The 1024Wh capacity contributes to easier portability, allowing the unit to have a length of 15.7 inches, a width of 8.3 inches, and a height of 11 inches. The weight of the power station is 27 pounds.
With the two large handles on either side of the unit, moving around the DELTA 2 is straightforward. Not having to deal with a foldable handle is a relief because those tend to feel awkward holding and carrying around a heavy load. You can easily store this in your house in an emergency or place it in your car during a road trip.
If you’re already familiar with Ecoflow DELTA power stations, you’ll be familiar with using this unit. If not, then no problem because it’s still easy to use. The main power button is on the side with the display, and you have to hold the button down for the power station to turn on.
You’ll hear a “beep” sound when the unit turns on, and the display will turn on. The display on this DELTA 2 power station is one of the best on the market; the screen shows the real-time input and output wattage. The battery capacity percentage is in the middle of the screen, and off to the left-most side is the estimated runtime that fluctuates depending on the unit’s output.
The display is bright, easy to read with large numbers and letters, and in a way, it feels snappier than other power stations we’ve tested. It has everything you could ask for without being too complicated and providing helpful info second by second.
Each section has its power button and once turned on, the button has a white light that turns on to show that the section is being powered. On one, you have the USB section and the display; on the other, you’ll find the AC outlets, DC ports, and input ports.
Off to the side of the DELTA 2 is where you can find the battery expansion port that you can use to plug in an extra battery.
Structure and Material
The build quality of the DELTA 2 is the same as EcoFlow’s other power stations; the unit has a solid build with nothing loose or flimsy. The handles are especially strong, and you can hold onto just one handle, and even then, there are no signs of structural weakness within this power station.
Of course, like with most power stations, the build may be strong, but you should not drop it or expose it to water. Both water exposure and dropping the unit may damage it.
The unit will automatically turn off when powering appliances over the 1800W max output for the DELTA 2. However, if X-Boost is turned on via the EcoFlow app, the max output is bumped to 2200W, so anything above 2200W will automatically turn off the power station.
Internal fans change speed depending on the wattage output and input of the power station; for example, the fans run at their max speed when the DELTA 2 is recharging because of the 1200W input.
For the price, wattage output, battery capacity, and the new LFP battery type, the EcoFlow DELTA 2 may be the most reliable power station on the market. The only unreliable part is the 1,024Wh battery capacity which can be a letdown for running higher-wattage appliances because if you’re using a 1000W appliance with this power station, the runtime will be an hour or less.
On the bright side, the LFP batteries ensure that you can rely on this power station for 3,000 plus charge cycles; this is much more than regular Lithium-Ion batteries can offer, making purchasing a power station much more worth it. There is no shortage of fast charging ports or AC outlets on the DELTA 2.
The size and weight are as portable as it gets with its capacity and output, making it easy to move around when needed, and it is small enough for easy storage in your home when you need it in an emergency.
The EcoFlow DELTA 2 is a slight but, at the same time, much-needed upgrade. The capacity falls short at 1,024Wh, which can be limited when you want to run high-wattage appliances for a long duration. The good thing is that the DELTA 2 uses LFP batteries that have a much longer lifetime, which is imperative when dropping some serious cash on a power station. The feature of expanding battery size can be very useful.
The 1800W and all the ways you can use the power station are enough for nearly all consumers.
Using the DELTA 2 power station is simple to use with just a press of a few power buttons, and the screen gives you easy to reads stats such as output, input, and estimated runtime, and it shows you what sections are powered on and being used. The addition of the EcoFlow app is another edge that EcoFlow power stations have over the competition because it lets you control the unit’s functions remotely and access features that practically unlock more power from the DELTA 2.
The build of the DELTA 2 is strong, and everything holds solid. You can even hold one of the handles freely even though it may feel wrong; the power station will be fine. The internal fans do an excellent job keeping the unit cool and changing speed depending on the output and input wattage.
It would be best if you didn’t expose the power station to water or drop it, though, as both can damage it.
Being able to power nearly any appliances you want at this price is excellent, and the LFP batteries make it so that you can rely on that power station for much longer. The sacrifice is the relatively low battery capacity that can be remedied with an extra battery that you can connect to the side of the DELTA 2, a new feature of the DELTA 2 power station.
If you’re searching for a high capacity, a high-wattage power station with plenty of charging ports and outlets, and you’re alright with dropping at least 1,000, then the Ecoflow DELTA 2 power station is the one you need. Honestly, even if your budget is 500, we urge you to consider the DELTA 2 because of all its functions, the Ecoflow app compatibility, and the use of LFP batteries; the DELTA 2, in many ways, is priced too low. We recommend it on all fronts.
