Anker SOLIX C1000

The first-generation C1000, replaced by the C1000 Gen 2, which recharges faster and puts out 2,000W. This one keeps the expansion-battery port Anker dropped for Gen 2, which is its only reason to exist now, and Anker's UK store showed it sold out on 21 September 2026. Buy it only if you find stock and want to add capacity later.

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, from a microwave to a hair dryer to small power tools, but there's no extra-battery port, so 1,024Wh is the ceiling.
