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

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.
