- PraiseGranolaAnother great addition to the EcoFlow Delta series!The Delta 3 is nice! I purchased this unit in March 2025, and added it to my growing EcoFlow collection. I have a few River series units and a Delta 2 with an extra battery. The Delta 3 arrived quickly, and setup was a breeze. EcoFlow offers an optional, free-to-use mobile app, which I have, and it recognized the device immediately after start up. The D3 works straight out of the box too, so if the mobile app isn’t your thing, it works just fine without it.
Since it’s a 3rd generation unit, the Delta 3 has a lot of new features available in the app that my first and second generation units do not. I particularly like the remote shut-off feature, where I can go in the app and turn off the device in case I forget. Another new-to-me feature is the real-time power usage and history. Since I recharge the unit using solar, it’s great to see the history and daily solar power generated by the connected panel. I also like that all of the AC and USB ports are on the front of the unit. This is great since I store the unit on a heavy-duty shelf against a wall with my other devices.
The Delta 3 is great, however I do have some small critiques. I did get two error codes during my first week of use. The first day I connected solar, I plugged the panel (EcoFlow Flexible 100W) in the night before. The next day, I woke up to error code 303, which is likely related to the inverter based on codes for previous generation Delta units. The mobile app explained the error and offered troubleshooting instructions right away. After the reboot, the device worked without issue and I haven’t see that error since. On a different day, after charging the D3 via AC power, I briefly encountered error 471 when unplugging the power cord from the outlet. It’s a quick error that appears on the D3 screen but doesn’t last long enough for the mobile app to show any information. I’m not sure if it’s actually an error or just a power blip when unplugging. It doesn’t happen every time, but I have seen it a few times since March. In general, I’m not worried about these two errors. The Delta 3 comes with a 5-year warranty, so if I have any issues in the future, I’ll reach out to Customer Service for support.
Overall, I think the Delta 3 is a solid addition to the Delta series line up. If you’re new to EcoFlow and considering this unit, it’s a great one to start with. Note I said “start with”, because you’ll love it enough that you’ll want to add more devices to your collection! Definitely look for a Daily or Lightning Deal and EcoFlow coupon checkboxes on the item listing to get the best price. Not to be confused with the Delta 3 Plus, which is another great unit, the Delta 3 also comes in a 1500Wh capacity in either the black or silver finish. If you are trying to decide between the Delta 3 1024Wh unit (this one I’ve reviewed) and the Delta 3 1500Wh unit for a similar price, definite go for the larger battery. Whatever you choose, don’t forget to register your unit for warranty and *actively read the user manual* to learn how use and maintain your device for many years to come. Enjoy! - AdielEf EcoFlow is a very good option.I’m really impressed with the EcoFlow Delta 2. It’s powerful enough to keep my essential devices running during outages, and it recharges incredibly fast. I love that it can handle several appliances at the same time without struggling. The build quality feels solid, the app is easy to use, and it’s much quieter than a gas generator.
It’s not super light, but still easy enough to move around when I need it. Overall, a reliable and convenient backup power solution — definitely worth having at home. - Bill LangtonGreat Unit for the Price!What can I say - Ecoflow has breen one of the major players in the Portable Power Station market for several years. Their products are well regarded for their quality, capacity, durability and function! The Delta 2 has been a stalwart in the mid-level, 1024Wh space for a while and when Amazon reduced the price to the level I found this, it was a no-brainer to grab one.
As expected, it works flawlessly. It is more compact than one might imagine. The design with the built in carrying handles makes it exceptionally easy to move around. At 27lbs, it has some heft to it but it is still easy enough to get it where you want it.
The display is intuitive and gives you a quick and easy look at power in/out, remaining life, battery percentage, etc. Battery life has been on par with what I expect for a station with its rated capacity.
Charging with the included AC cord from a standard 110v outlet has been exceptional! It really charges quickly. With the LiFePO4 battery, you can expect 3000+ charge cycles or about 10 years before the battery falls to 80% capacity. Even then, the device will still deliver!
Ecoflow also has a matching spare battery that simply plugs into a port on the side of this unit and effectively doubles your capacity. They have been offering it at a very reasonable price as well. With that, you have a very capable power station that could provide quite a bit of power, all for less than $750 - which is what these 1024Wh units sold for all by themselves less than a year ago! - @@@Bruins@@@lot of powerso convenient power station. The EF ECOFLOW Portable Power Station DELTA 3 Classic is an extremely helpful power gadget. I'm now using the power station as a UPS. It turns out that a power station provides 400 percent more battery reserve than a similar-priced dedicated UPS. A power station has many more applications than a standalone UPS. I believe that power stations are more effective than obtaining a dedicated UPS.

Featuring a 1024Wh long-life LiFePO4 battery and 1800W AC output, it delivers reliable energy for home backup, camping, RVs, and outdoor use.
