A Delta 2 and battery backup were purchased Dec 2022 and installed with a manual transfer switch adjacent to my main electrical panel. This setup allowed for individual circuits within my home to be selectively powered for over 9 hours when the grid was down during the Jan '23 west coast storms. My refrigerator, microwave, internet router, lights, and forced air gas furnace remained in service thanks to the Delta2.

Received my DELTA 2 and 220W bifacial solar panel a few days ago. Also purchased the extension cable for the solar panel (the cables included with the panel would have been everything I needed, but I wanted some additional length). The shipping process was fast (about a week) and I received good notifications on progress. Both the DELTA 2 and the solar panel appear to be good quality, and initial tests align with the expectations I had based on the product advertising. My original plan was to use the product mostly as an easier source of emergency in-home power than my gas-powered generator, but I'm now thinking of some other potential uses as well (UPS/backup for sump pump, power in the far corners of the property, an occasional picnic or camping trip, etc). I'm not sure I'll be using the phone app given the potential security risks of hooking an emergency power supply to an internet connected device. So far, I'm very happy with my decision to purchase the products.

I bought this in Feb 2024 thinking I would need this due to an advance notice from our Electric Company (PECO) doing maintenance work in our area. It so happened in March 2024 our city was trimming trees and they turned off the power. I worked from home so I had no idea what had happened. So before I got panicky I remember that I had already fully charged the Power station a few weeks ago. And I finally was able to use it and it worked! I just had to remember to turn on the USB and outlet plugs. I also had the app on my phone. It was charged at 100% which gave me 3 hrs and 45 mins. I already had my router plugged in and the outlet for my computer and lamp. I would have put my refrigerator in but I chanced it and did not plug that in..since the cord was too short to reach the Power station. And since I had not gone shopping I was not worried about losing any food. The electricity did come on 2 1/2 hrs later. When it came on..I recharged the Power Station and put it back in the box for future emergencies. I would recommend for anyone who need a backup. I would have bought two for double the time..but a little expensive for now. And I did not do the solar paneling either. But for standby situations it was worth it.

I bought the Delta 2 and 220W solar and I am impressed with the engineering and packaging of the product. I love the capacity, fast charging and the ability to use up to 1800W appliances. Not heavy and slightly smaller than I expected even after watching many you tube videos.

I bought this unit after the major storms in California in 2023 as our house lost power for 4 days, and running the generator was neither efficient, nor did the job well. The plan was to use the Delta 2 to power the refrigerator and to charge the computers and flashlights. Specfically we wanted a battery that had fast recharge time so that we could both recharge from solar, and if the sun wasnt shining recharge it off the generator in a timeframe that didnt require us to keep refilling the gas tank and having to listen to the generator all day. The Delta 2 works great! it recharges off solar faster than we are depleting it, and its so convenient that I have been using it instead of grabbing an extension cord to work outside on nice days. the display is intuitive, the app connects flawlessly, and the functionality is perfect. Its a really well thought out product that i would definitely recommend. I did a ton of research into other units from other brands and am happy I settled on EcoFlow.

I bought this generator because of a hurricane that left us without power for 3 to 4 days. I haven't really tested it out yet but it has been used and works great. I also bought the solar power panels to charge it. I will test it out one of these days.

I’ve only used this about twice so far as it arrived a few days prior to me being out of the country so I can’t honestly give it a full thorough review. However, my short use impression of it so far has been pretty positive. I love how it charges quickly. The weight of the device is manageable. I did notice the fans were a bit loud as it was charging. That’s as far as I’ve got in terms of playing with this new product. I only tinkered a little bit with the app and my first impression was it seem simple. I’m excited to wait for my return back home to fully test out this product. No pictures of my setup at this point in time, but will update one in the future.

Been using the D2 for about a week now with amazing results. With a flexible office location, bring the D2 outdoors to power up my home office is amazing. With the EF solar panel plugged in, I’m generating more energy than I’m consuming… Simply amazing

Recently in Maine we had a winter Storm come through that knocked out power in my area. I was able to use my Delta 2 to run my two elderly aunts sub pump, and furnace to keep their house dry and prevented from freezing up. It was able to run the furnace and sub pump for a few hours per charge which is saying a lot for how much energy those two would draw

I bought the Eco Flow Delta 2 and solar panel last month after lots of research on power stations. I have two small children and live in Michigan and needed something that could power a pellet stove in case power goes out in a snow storm. This can do that for like 12 hours. I’m also looking forward to having power for a fan and my computer in the summer. I love that it charges really fast and the solar panels give me extra peace of mind knowing I can recharge it easily if we are out of power for more than a day. It was a worthy investment.
