I purchased this when it was on sale for almost 50% off. The features are great. Very impressed with the quality.You have so many ways of charging all of your devices. My main reason upon purchasing was as a backup to run my refrigerator when the power fails. I'm now looking into a smaller Ecoflow unit for camping.

I actually have two of these. I bought this new on after having the first for aver a year and using it for everything from an overland camping power supply to powering my power tools for light construction projects without needing to run long extension cords from the house or barn. Fast recharging when plugged into a wall outlet. Solar recharging works to but of course is much slower. Money well spent if you find it on sale.

October 2022 purchase. Charging from 200 watt fixed solar panels off grid. Purchased EcoFlow adapter. I have used a 1500 watt water kettle, induction cook top, and 12volt cooler 24/7. So far so good but if there are any issues I hope the company has options for repairs in California.

I bough my original delta a couple years ago. And liked it so much i ordered a delta2 and i just ordered my 3rd delta2. Right after i got my first delta 2 we lost power due to downed branches from a storm. I just plugged my 5 watt usb lights into the delta and i used the original delta to run my frige. I used the delta2 to power my cable modem and router. For some reason it still works when we lose power. These things work so good and charge so fast i just ordered my 3rd delta 2. I ran my basic power needs all night and the next day i went out and started my generator and charged the ecoflows in less than 2 hours. I was ready for another night of quiet power. My neighbors generators where running all night and day. I only run mine to charge once a day.for about an hour and a half. The fast charging is what sold me and the built in inveter. Its just so easy and they only weigh about 27 pounds so you can move them where ever you need power. Makes those power outages easy to deal with.

I bought these items about 4 to 5 weeks ago and so far it has good a great investment. I live in Florida, we have hurricanes every year and power goes out, sometimes up to 5 days. Now I can rest assured that my family will have power. Thank you Ecoflow for making such a great items. Plus putting them on sale so the working class people can make this investment.

During hurricane Ian we had no power and no cable service and could not watch what was happening around us. Since then I bought an antenna to hook to a tv but knew I would not run generator till storm was over. EcoFlow DELTA 2 solves power problem I ran TV for 2 days to test and it worked great.

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.

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.
