I bought the Delta 2 a month ago and should be great for power outages! I tried it out on a Ninja Xl grill consuming around 1700 watts and it worked flawlessly. I’ve also tried the Delta 2 on a refrigerator and other small devices. It should be just fine as a backup for power outages. The true test would be on a sump pump and for how long. Maybe when Spring gets here I will try it out but I think the extra battery would make me feel more comfortable. If I get a good deal I will purchase the extra battery! ;)

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 have several Power Stations, even some I built myself, but nothing come close to this. EcoFlow has really outdone themselves. The feature rich unit is strong, powerful, yet extremely lightweight and even expandable. I bought the Extra Battery as well. The ease of use and portability make this my favorite hands down. This unit packs a ton of power and features into an really small package. The WiFi feature allows me to keep an eye on it from anywhere, Just like my off grid solar for my home. I can easily look to see the SOC, loads, solar input and many settings. The Delta 2 along with the Extra Battery are the best companions for off grid RV’ing, parties, worksites, power outages, emergencies and so much more. I reach for the Delta 2 and its extra battery when I need power to go from now on. I have portable solar panels to keep it topped off. This is by far my favorite power station, and I highly recommend it to anyone looking for one. It gets 5 stars from me!

After months of reviewing various companies and their systems, we went with the EcoFlow Delta 2. We got two units, one for upstairs, one for downstairs, and a battery backup and a solar panel. When we received it, we literally opened the box, plugged it in, and very quickly (well under an hour?), it was fully charged! Truly a plug and play. The units are light enough to pick up and move around without a problem and to store in a small place. We haven't tried the battery backup or solar panels yet, but by every indication it will be a simple procedure as well. I love knowing that we can keep basics going now during a power outage, and have enough power to last quite a while, while being able to use the solar panels to recharge the units. If you feel intimated like we did, this is for you! Our next step will be to work up to a Pro for a whole house system, but until then we feel this was the best option for performance and price.

Honestly happy I waited and bought this EcoFlow generator over competitors. With the LiFePO4 battery this generator will be around for a while. It's quick to charge, and some say it's loud, but I do t believe so. The interface is easy to use and the app gives you the ability to customize how the generator functions. I was able to watch t.v., charge my phone, and laptop for 4 hours and the battery only dropped about 30%. Can't wait to take it out camping this spring!

I just received my EcoFlow Delta 2 today and everything that was suppose come in package arrived in the box. The Delta 2 was in perfect condition with a 29% charge. I downloaded the App and proceeded to charge it to 100% and I was to change the charge rate easily with the App. The Screen is very easy to see with all the parameters clear and understandable. I am confident when I need the power I will have it and I will order the Delta 2 Smart Battery to supplement the WattHours.

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 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 bought the the Delta2 and 220W Solar Panel combo for camping trips to power my Dometic CFX3 45 fridge. The combo worked perfectly during a 7 day camping trip. The weather was a little cold out, but this Delta2 was capable to power the fridge for 3 days which is quite impressive. The solar panels worked perfectly and I could get 218W when aligned directly to the sun. This is a great combo for anyone with extended outdoor activities. Great job EcoFlow!

Usually available at a great price/performance point; LFP batteries are far superior to LiPo; good mix of performance, cost, and weight. How god will it do? On 12 December 2024 I plugged my new 100% charged Delta 2 into my house transfer panel and put the refrigerator and furnace (4-zone forced hot water, burning natural gas, so the electricity is needed to pump the water around the house) onto it. I consider these my 'super critical' loads that if lost make life unbearable. With outside temperatures in the upper 30's to low 40's (Fahrenheit), the Delta 2 ran them for 9 hours.
