Anker SOLIX C300

A sensible small-capacity pick if you just need to keep devices charged — two AC outlets is one more than most rivals this size. Note there's also a cheaper DC-only 'C300 DC' variant with no AC inverter; make sure you're buying this AC model.

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.
