Is it for you

Buy it if

  • Home backup where a desktop or router has to ride through an outage without rebooting
  • You want to start at one kilowatt-hour and add capacity later
  • Big solar arrays, since it takes up to 1,000W

Skip it if

  • It will run at high output near people trying to sleep
  • You carry it more than a few yards at a time

The DELTA 2 is gone, and this is what replaced it. EcoFlow’s pitch has always been the wall charge, and How-To Geek measured it pulling 1,350 to 1,400 watts, full in under an hour. For a blackout that ends and then comes back the next evening, that recharge speed decides more than the capacity does.

The switchover figure is the other reason people buy it as home backup. Under ten milliseconds is quick enough that most computers and routers never notice the grid dropped.

Six AC outlets, three of them grounded, is double what the Jackery offers. Two 140W USB-C ports will charge a large laptop at full speed without the inverter running at all, which also saves battery.

The cost is noise and heat. How-To Geek could hear the fan over a 700W vacuum, and the unit runs warm at high draw. It is also the heaviest of the one-kilowatt-hour units on this page at 27.6 pounds, and the front-panel buttons are hard to read in low light.

Expansion packs are the long game here. If you think a bigger battery might be next year’s purchase, this is the only unit on the page where adding one is a matter of plugging it in.
