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 Max Plus

Big enough to run most household appliances (including a kettle) but still merchandised as 'portable' by EcoFlow. A strong middle ground if the smaller DELTA 3 isn't enough but a fixed home-backup unit is overkill.
