How it scores
The rating comes from 8 measured or published factors, each scored 0-100 against fixed reference points for its size. How we rank explains each one.
Independent capacity tests
Usable energy delivered from a full charge through the AC outlets, as measured by independent reviewers. Inverter losses mean no station delivers its full rated capacity.
