Bluetti AC70

If you don't need a full 1kWh or 1,800W, the AC70 delivers most of the usefulness for noticeably less money. Power-lifting surge mode helps it punch above its rating.

EcoFlow DELTA 3

Now EcoFlow's mainstream 1kWh pick, built on a 3rd-gen LFP pack EcoFlow rates for a 10-year lifespan. 1,800W continuous (2,400W via X-Boost) covers most single appliances — microwave, hair dryer, small power tools — but there's no extra-battery port, so 1,024Wh is the ceiling.
