Bluetti AC70
If you don't need a full 1kWh or 1,800W, the AC70 delivers most of the usefulness for noticeably less money. It is 1,000W rated, 1,500W surge, with a 2,000W Power Lifting mode for resistive loads that helps it punch above its rating.

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.
