We use thisDelta 2 Max to power our off the grid riverside cabin with lightning , tv and fan and sometimes a small a/c unit. We charge it at home using a/c power or we use the solar panels.
I bought the EchFlow Delta 2 Max with an extra battery. Looking as a backup power source when/if the power goes out. Tested it on various small to medium household appliances and it worked excellent and charged it up every fast. Ready for another use. I also bought last year the Delta Pro with two extra batteries was able to power two refrigerators for 24hrs before needing to charge. Looking forward to making some solar panel purchases next.

Bought for CPAP usage

I have a cabin on a piece of land I own that doesn't have electricity so I have been searching for something to power my CPAP (Resmed AirSense 11) instead of using a car battery with an inverter. I managed to get 8 days of usage out of the unit with the spare battery. I was using the AC power and did have the heated tube on along with the humidifier. Average usage per day was right at 11hrs. I have yet to see how long it can go using DC power and without the heated tube or humidifier, but I would assume it would go much further than 8 days. Hands down beyond pleased with this unit and the spare battery!

Bought the Wave 3 and Delta Max 2 very impressed with the quality of the product. We had a bit of a snag with logistics. So I reached out to EcoFlow and within a couple of hours the issue was resolved. The product was delivered the next morning. Should make for a great addition to the family camping trip this weekend!!!! 5 Stars!!!!!!!
