I needed a reliable, smart portable power unit for the remote utility shed on my property. There's no utility electricity out there, but frequently I need to run power tools and lights around my tool boxes. Reliable, safe, easy to transport... and I can monitor it back in my home!

Having owned several brands of portable batteries for our off grid solar living, I was pleased to receive the DELTA 2 addition recently. The battery is extremely fast charging, reliable, and as advertised. Well designed and the app is a plus for monitoring. I love that it is lithiumFE battery based which will allow many cycles of charging.

I originally purchased this to run a diesel heater while camping, but it has done so much more. It will run this heater a solid 3 days. It is also great for running LED lights inside my tent as well as blowing up an air mattress. I was originally going to purchase a smaller unit, but I'm so glad I chose this one as it will run everything that I need and then some!

I liked my delta 2. I used multiple times on my full size fridge during outage. The best part is you don’t need to go outside during storm run your gas generator. I made a lot of researches first I was planning to with gas generators later I saw battery powered ones and I made good and long researches to find best company I went with ecoflow

Picked up the Delta 2 just in time to put it to the test in a power outage. Ran a full size refrigerator in the garage for several hours at an ambient temperature of about 60 F. Plan to pick up the extra battery for extra insurance or to run a freezer as well. Charging from AC was lightning fast but a bit noisy. Hope a firmware update in the future can help with the fan speed. Couldn't be easier to set up and get going, plug and play. Highly recommended!

I recently purchased the Ecoflow Delta2 to provided backup power to our home during power outages. So far it has exceeded my expectations. The battery has lasted longer than expected so I'm looking for more things to power. A nice feature that I wasn't expecting is the UPS feature. I have my mini frig plugged into the Delta 2 so that when power goes out, the Delta 2 automatically switches over from home AC power to battery backup. Although the battery lasts longer than expected, the ability to add extra batteries in the future was a key feature since I didn't know what my power requirements will be in the future.

I bought this the day it a came out with x2 220w Solar Panels. First solar panel test gave me above 420W continuous on sunny day - as advertised. I love the access the app gives me to the power station’s controls. Tested with hairdryer and was very happy with the units readings - accurate. This unit packs a lot of features with a good price point. I am very happy with my purchase.

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.

I bought my Delta 2 bundled with the 160w solar panel and a 220w bifacial solar panel at the end of Nov. 2022. Ihave gone through 7 generators in 4 years living in SE Oklahoma. My delta 2 can fun my unefficient old apartment sized refrigerator freezer combo for about 8 hours. It can run my 5000 btu ac window unit for 2 hours. We tested it out on a friends older toaster oven using 1800w and it did great. This time of year is easy because it isn't hot and we use wood and propane to heat and cook. I was thinking about getting the delta max extra smart battery but they are sold out of them, even the refurbished. After a little thought though, I have decided to buy a second unit because it can be used independently from the first where the batteries cannot. I have had an issue though with mentioning. My power station was at home while I worked. There was nothing being plugged into the unit. For some reason it was flashing over load when I arrived home. It would not take a Chaffee of any kind from the solar panels. For 3 days I went without any power worried that i could damage it worse somehow. I chatted with technical support. Nothing they offered did any good. I decided to discharge the battery all the way down and see if i couldn't get it to rest because they didn't include a hard reset on the delta 2. The screen said I had 1 minute at 1 percent. I ran this thing for 4 hours using everything i could find to plug in. Finally it went down. After a couple of minutes I set up to charge at a friends house using the wall plug. It took the charge at half the normal charging speed. I plugged in his ac and it drew 800 watts and the delta 2 vgargubg watts went up to tge normal 1350 watts. I disconnected the ac and it continued charging at 1300+. I used it and it worked as normal. Only now every time I charge by electrical plug I have to temporarily plug in something to pull enough watts to raise how high the delta 2 charging watts go. Today is the first sunny day I've had that I'll be able to test the solar panels again to see how they do. Otherwise my unit is fine. So use your common sense. The support people aren't helpful immediately but will get you to the right people to talk to. I still recommend the delta 2 for everything it can handle. And by ordering a second unit it will help me cover what the extra battery would have given me the power to do. But I have the ability to use it/charge it seperately. The peace of mind that if something happened to 1 them the other could get me through until the issue was fixed. And I will be able to power twice as much if need be. Happy shopping! DEFINETLY RECOMMEND!!!!

I just received my EchoFlow Delta 2 last week and set it up with the 220 Watt Bifacial solar panel. In North Carolina on a sunny day it charged at up to 195 watts just from the front of the panel. I let it charge for a couple of hours and increased the charge on the Delta 2 by about 20%, I the plugged it into the electric and charged it the rest of the way at 600 watts and it charged flawlessly. I left it fully charged waiting for Hurricane Ian to pass and hooked it into my refrigerator, to see how it does at running it. The Delta 2 has done very well and I can fully recommend it to everyone
