Excited to now have over 3KW hours of power (this plus extra battery plus two 500 WH power stations I already owned) along with solar panels dedicated to each of the three power stations. Not enough to run my whole house; but, certainly makes me feel better to know I can run the fridge and furnace if needed for a day or more (not counting solar recharging).

I've been using two, 1.5 kilowatt hour lithium ion power supplies to keep electronics, fridge and small chest freezer going for a several hours. I decided on the DELTA 2 based on improved specs, more and quicker re-charge cycles and several other features. So far everything is working well, including the wireless connection and even the FB resource where people in the know explain, help fix and guide new EcoFlow users. Having purchased the DELTA 2 so recently, I cannot report on durability, firmware support and other functions like serving as an uninterruptible power supply but fingers crossed that those things work well.

The set up was pretty easy but for the large amount of booklets etc that come with it there is VERY LITTLE information. Need to see what it can and can’t be used for, troubleshooting etc I haven’t fully charged it yet-trying to do solar but I needed the extension for the solar panels. I have the unit and back up battery and with my less than perfect solar panel position it has been charging about 1/3 of one battery inn6 hours

I live in Texas where the power goes out regularly. I needed something to run my window unit, rolling air conditioner, refrigerator and fans this summer wholes it’s been 110 degrees. The Eco Flow Delta Pro does it all and more. I feel confident in my home now. Thank you Eco Flow.

At first I was very hesitant to buy a portable battery for my business, but after doing my research I came to the conclusion that the Ecoflow Delta 2 was the best option for me. The price is also very affordable and it has really served me very well and without any problems.

Very good for backing up necessities during a power outage, and I plan to use it instead of installing an inverter in my truck. I have a river 2 max for my CPAP, and already had a EF220 watt solar panel for that, so when I got the D2 I purchased a second 220w portable panel. Charging from the grid, solar, or an inverter generator is pretty quick and easy. I can now run my refrigerator, small chest freezer, and CPAP with plenty of extra capacity for “comforts” and have more options than just firing up a generator (which isn’t always easy or convenient, and definitely not quiet).

I have another unit from a different manufacturer. Same size. The Delta is crazy efficient with solar charge. Charging at 200w where my other unit is 140 w. And. The Delta can go to 500w charge. Crazy. Charges in almost half the time. In all other ways it's comparable. But charge time is key when you have your appliances plugged in and you want to keep them running while charging. Very nice unit. Love the Delta 2. Would like a less expensive option for a second battery. But what you gonna do.

We bought the Delta 2 and the 110 watt solar panel for emergency backup and to also power our new Iceco Go20 for when we are camping. The Delta 2 can run the Iceco Go20 for a little over 3 days before it needs to be recharged. It has enough power to run a standard electric coffee maker and a Keurig coffee maker. When using household power to recharge, it usually takes less than an hour to recharge the unit. We recently bought another Delta 2 and 220 watt solar panel to add to our capacity. The app for the Delta 2 is awesome.

I took the Delta 2 on a two day camping trip. It was able to run my cpap for two nights. Charge fully 8 phones and 3 Apple Watches and at the end of the trip still had 40% at the end of the trip. The night time temps got down to 37 degrees each night. I was surprised at the performance and would definitely recommend.

I bought my battery back up and extra battery a week or two before our 1st major windstorm here in Buffalo. Just wanted it to run the sum pump only. Well, during the storm the power went out for 3 days. Yes the pump kept running for all 3 days. I do have a generator but only brought it out just in case I had to charge the batteries. For the three days the batteries went from 100% to 22%. Fantastic products!
