Our verdict
This one isn't very close. The batteries are nearly the same size (1,024 Wh for the EcoFlow, 1,070 Wh for the Jackery), so runtime is a wash: about 15 to 16 hours on a typical fridge either way. After that, the DELTA 3 Plus wins most rows of the spec sheet.
It puts out 1,800 W continuous against 1,500 W and surges to 3,600 W against 3,000 W. It has six AC outlets to the Jackery's three. It takes 1,000 W of solar, more than double the Jackery's 400 W, and it charges faster from the wall too. Its switchover is quicker (10 ms against 20 ms), which matters if a desktop PC or a router is plugged in when the power drops. And it can grow to 5,120 Wh with extra batteries, which the Jackery can't do.
The Jackery's real advantage is weight. At 23.8 lb it's almost 4 lb lighter, and you notice that carrying it to a campsite. If that's what it's for and three outlets are enough, it's a fine choice.
For home backup we'd take the DELTA 3 Plus. One thing to know when you compare the warranty and cycle numbers: Jackery's 5 years is 3 plus 2 more when you register, and its 4,000-cycle rating is counted down to 70% capacity.
How we compared: the makers' published specs plus our runtime calculations. We haven't bench-tested these units ourselves.
