EcoFlow DELTA 3
The short answer
This is a 1,024Wh battery with 1,800W of output, which means it stores about 870 watt-hours you can actually use and can run anything drawing up to 1,800 watts at once.
It runs indoors and makes no fumes. Of the 15 household loads we track, it can handle 13. It would keep a refrigerator going for 1.2–8.7 hours.

We have the maker's power and battery figures, so the planner can size it. We have not yet checked the manual, the solar and wall-charging limits, extra batteries, the warranty, the official add-ons, or safety recalls.
Treat this as a model to research, not one we vouch for. The fully researched models have all of that.

Title states 1024Wh and 1800W, matching our record exactly. A price is not a product attribute: treat this as the figure at capture time, not today's price.
Some links on this page are affiliate links. If you buy through one we may earn a commission, at no extra cost to you. It does not affect which products the planner recommends: rankings come from the sizing rules on our methodology page, and a product with unresolved safety identity is never ranked or linked regardless of commission.
