I do a ton of overland upland hunting and this power unit has been amazing. I’m able to take 7-10 day trips off-grid and still have the ability to charge my dogs collars, GPS unit, phones and laptop for the occasional rainy day movie day. The only thing I would change about this unit.. getting the solar panels with the unit and hardwiring into my truck. But I don’t have a truck rack on the roof so I couldn’t do that. Other than that.. zero complaints from me.

I'm not a gadget person. When I got the DELTA 2, I found it easy to follow the instructions to charge it and discharge it, running various appliances. Laptops were fully powered in a couple of hours. I plan to use it at home during power outages, so, not very often, but I will make sure to follow the maintenance instructions. I love that the unit recharges so quickly. I thought the DELTA 2's heat and noise when running were mild, very acceptable. The unit feels sturdy and has convenient handles for moving it. I like the EcoFlow phone app. I made a cheat sheet for my own appliances (e.g. freezer, single cooktop, etc.) so I know what I can power with it, and for about how long. I keep the cords, instructions, etc. in a pouch attached to the unit.

I bought this to replace a smaller unit that could not backup my fridges or freezers. It is much lighter and more functional than the Delta 1300 I purchased a few years ago. I prefer the LiFePO battery and it's associated longer life. It does not have as much battery capacity as the Delta 1300, but the inverter appears to be the same. I like the ability to set the charge limit to 70% while using it as a UPS. The UPS functions very quickly and has been running a freezer and some other appliances without problem. It was a little slow to update the firmware when I got it, but it seems to be doing fine now. I don't like that one must connect the device via WiFi to get updates. It wants access to my home network and that is forbidden to the Chinese (and other) companies. Overall, I like it and it works so far as a UPS for my freezers and fridges.

I live in New England and it is possible that we will have rolling black outs this winter which is why we purchased the Delta 2. A wind storm this week knocked over a tree and we were without power for several hours. I was able to hook up lights, my computer, and monitor, my warming throw blanket over my lap and use my phones personal hotspot. This enabled me to continue working. My husband also hooked up our Kerug so we could enjoy some coffee.

The January 2023 rains here in California were brutal. I tried to expedite a battery from EcoFlow…and they came through! When the power outage hit..this battery kept a few lights on and powered all our devices. It even powered our Dyson heater. The ExoFlow Delta 2 was amazing.

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!

I really like the unit, it’s got good power and capacity for it’s size. I do have some thing’s I’d like to be different though, all in the app really. First I also have a delta mini and i wish i could choose to have my Delta 2 homepage style be like the mini style, i like that one more. Second, i wish i could see charge cycles listed in the app. Other than those small gripes i love my unit and use it to power my vacuum pump.

Customer service is easily accessible. Product is 85% perfect. Reasons for 4 vs 5 stars below: 1. It needs a larger 12 volt Connection, over the 12v. 10 amp provided, (at least one 10 amp @ 13.5v. and two 15 amp @ 13.5v). 2. The Cooling fan is unnecessarily WAY TOO LOUD. It is controlled by charge or discharge wattage. It should be temperature controlled and redesigned to be quieter on its highest setting. 3. The Auxiliary battery should be connected in the back like all the other connections. Plus the auxiliary battery wire is too thick and stiff. Please don't BS me and say it needs to be that way.

Great Unit! But,....Needs a few tweaks to make it a Five Star for me. I hate that every time you turn on the unit from the front control panel, you have to reach behind to push a little button that is hard to find so you can turn on the 120 volt power. I bought this to power up our Christmas Lights in our fifth wheel slide out that has no 120volt power in the slide. the thing that sucks, we push it way back to hide the Delta-2 and all the cables. it is easy to turn it off at night as it turns off with the push of the main power button.. the nightmare in when we need to pull it all the way back out every day to try and hunt down the 120 volt power button. PLEASE CHANGE THIS ON FUTURE UNITS.

This is not a UPS (uninterruptible power supply) system. It does work well as a power source, but if you want it to keep your pc running when the power goes out...it does not...when the power goes out the back up power takes over, but the split second during the switch powers down your pc...so not a good choice for keeping your pc running contiuously during power outages.
