EF ECOFLOWPortable Power Station DELTA 2, 1024Wh LiFePO4 (LFP) Battery, 1800W AC/100W USB-C Output, Solar Generator(Solar Panel Optional) for Home Backup Power, Camping & RVsClimatePartner certified

I have 4 Ecoflow portable power stations and they all work great. I like the Delta 2 units because they don't weigh too much and are a great value when on sale.Pros: Will power pretty much anything in your kitchen with the 1800 watt inverter. Charges quickly in 1 hour off of 120 volts. It has 1024 Wh battery but only weights 27 pounds. Has 120 volt, 12 volt, and USB outputs. Great for camping, travel, or powering appliances in your trailer.Con: The inverter consumes about 10 % of the power which is pretty normal for inverters. Will not run some power tools because of the high power surge lasting several seconds.

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!

This is my first backup power supply I've ever bought and I'm very happy with it! It's a great alternative to using a noisy petrol generator. I bought this one because my needs were the following: a. Something to have while camping that can run appliances and charge gear up, such as smartphones and/or cameras/gopro's. I've tested this with my Blendtec (similar to a vitamix). And it worked awesome. I was able to run it full blast and it was only pulling about 600w or 1/4 of the total allowed by the unit. I was also able to run a projector, chromecast, speakers and a lamp for about 12 hours. When I checked, the Delta 2 still had 55% battery left. As for size and weight, I personally found it easy to manage. Smaller than a desktop computer and fairly light. I also purchased the Waterproof case for the Delta 2 which allows you to run the unit while inside the bag. There are flaps you open that allow the fans to pull air in and out. A real nice touch. The only complaints about the bag are: 1. There's no handles or shoulder strap on the bag so it's kind of awkward carrying it. 2. There's only 1 pocket on top of the case and it doesn't allow much to be put in there. It would of been nice to include 1 large pocket on the side that you could add a power strip, multiple charging cables, the 12v DC cable, and instruction manuals inside. My plan is to use this with an Electric Cooler. If you want to do the same, be aware that the Delta 2 gives an approx time of 16-32 hours for that. If it's really hot, it might zap the battery in less than 24 hours. Hopefully the electric cooler you own has: a. a power supply of it's own to use first before needing the Delta 2 and b. Your cooler offers Eco Mode which won't pull power the whole time. If it has both of those, I imagine you could camp for a few days and have power the whole time if you're not using the Delta 2 for much else. Otherwise you should get a bigger unit like the EcoFlow Pro or Max. My plan is to get the 2nd backup battery. I'm eager to see the new upcoming Ecoflow Electric Cooler that was just showcased at the CES show. It looks really nice and am looking forward to using both the Delta 2 and the Glacier cooler combined! One odd thing about the Glacier is they said it only works with Solar or AC. Didn't appear there was a DC option. As for the Delta 2, you get AC, DC for your car and the solar cable connection cables. You just need to purchase the solar panels. I might try that down the road. I only go camping for a few days. Also, the mobile application works great with the unit. Of note: At first I was confused using the application. I was able to connect via Wifi and when I wanted to try bluetooth, I couldn't get it to work. The reason for that is because the unit will use Wifi if it's available. So if you're at your house and want to force bluetooth to work, you need to sever the wifi connection completely so the only option for your phone and delta 2 will be bluetooth at that point. Once I figured that out, BT worked perfectly. There is no need to go into 'connected devices' on your phone and add the Delta 2. It's fancy enough that it just works automatically. So overall I'm pretty happy. This is offering me enough backup power at the moment. I didn't buy this to power my house for 24 hours when the power goes out. If you want that, you should look at the Ecoflow Pro. It has 4x the power than the Delta 2. The 3 stars for Noise is a tad unfair. It shouldn't surprise you that this has a loud fan when charging 1850w in 90 minutes while plugged into the wall. That's 1200w of input. But guess what? In the mobile app you can lower the intake of power when charging. If you lower it all the way down to 200w intake, it will be as quiet as a desktop computer. I was able to charge the unit 55% over the course of 5 hours with it on 200w. If you go with 800w the fan will kick on but it won't be as loud as the fan on High when intaking 1200w. So it just depends. Do you really need your Delta 2 charged up in 90 minutes and it's completely dead? Then you'll have to go with the loud fan. But you can hopefully just plug it into a room that no one is in, like your garage. I've found I'm fine with charging at the lowest 200w intake and just letting it take 10-12 hours to charge. But everyone is different. Have fun!

I haven’t done the Professor Hobo challenge, but with initial use it has performed DC and AC power, charging and fan use. Working great and was a great price on sale after the new version with minimal extra features came out. Seems very good for brief home outages, good for tent or truck camping et c. at this power to weight balance. Not waterproof but I got the package with a vinyl case at no charge.

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.
