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, with a higher-rated 4,000-cycle 3rd-gen LFP pack than the DELTA 2 it replaces. 1,800W covers most single appliances (microwave, hair dryer, small power tools) and it expands with extra batteries if you need more than 1kWh.
