Style: DELTA 2
I downloaded the app from the App Store. I’m sure my CCP monitor will approve of this review. Intended use of my units: partial home power backup for small devices/appliances while experiencing a power outage. To be a stop gap while generator setup is performed. Would then be used for nighttime operations of refrigerators and tv setup to relieve generator. There are several more in depth reviews with users having utilized killawatt plugs or an oscilloscope. I have not done this. This review is based upon a single test use only, but I am pleased to this point with only one small gripe. The gripe first. I purchased two Ecoflow Delta 2 units on Black Friday for a considerable discount. One of the two (this one) was a Delta 2/200W (x2 100W panels) solar panel combo. The gripe is related to the solar panel. The unit is supplied with the connectors to link the panels which is as expected. However, the panel to PSS cable isn’t particularly long. If you want to say…leave the battery unit inside while your panels are mounted outside while you charge…well, you will need a male to female XT60 extension. That’s a small gripe, but it will mean another purchase. A 15’ cable inside of the 6’ cable would let me put panels outside while my Delta 2 is more safely kept inside. End gripe The unit seems reasonably sturdy in built. The assembly is tight and nothing rattles or creaks. The fan runs during charging and discharging as needed. It is not particularly loud in my opinion, but this is quite subjective and some may be more sensitive. The display on the unit is adequate telling you remaining charge and consumption rate while using or remaining charge time and input rate when using the AC cord or panels. The app is actually pretty good and easy to use. The unit can be turned on (at the device of course) and left in standby mode with no outlets active until you decide to power them up/down via the manual button or the app. I have not tested how long the device keeps charge while in standby and no outlets active but without load. This would take a long time and I do not see the point of leaving it in perpetual standby. I do like that you can designate upper charge capacity and lower discharge limits via the app. To me, this makes maintaining the device much simpler. I recognize that some will not appreciate the idea of limiting how fully you charge the device as it cannot be known when an outage will happen. Many will want to keep the device fully charged. I plan to follow Ecoflow’s guidelines for maintenance and charge state between actual need of the units. While LiFePO4 batteries are more forgiving, these are expensive and I’d like to keep them within warranty. This is why I got the solar panel option to supplement charging from my generator during an outage. The Deltas can power small items to give the generator a break at night or during oil changes and refueling or simply to help save fuel. The unit is about 27lb. It is not overly heavy for its size but take this into consideration as you may not want to move it a lot during use/storage (see gripe about XT60 cord length). It is early, but so far I am very happy with the quality and capacity of the units. One will run my stove blower for hours, or power the entertainment center for several hours and a refrigerator overnight based upon observed rate of discharge. These appear to be a good supplement to an outage protection plan.

Style: DELTA 3
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!

Style: DELTA 2
Why did you pick this product vs others?: It is what I could afford. Works well. Got it after going through hurricane Helene 2024. I have used it during several storm power outages and the device has worked well keeping my internet up and running and supplpower to lamps, fans and charging phones. Works better than the ups(backup power) I have installed for my internet devices. It barely last 45min. The ecoflow easily last 13hrs according to the timer on it. I plan to purchase a solar panel(s) to charge it during power outages.
