How the spec bench works
Published specs only
Capacity, rated output, surge, chemistry and weight as the maker lists them. No guesses filled in: a missing number shows as a dash.
We do the math
Wh per pound, runtime for common devices at 85% inverter efficiency, and which models clear your load. Every number is computed from the spec sheet.
No hands-on claims
We have not tested these units. Picks follow a stated rule (popularity on Amazon US inside a size class), and superlatives only when the number proves them.
Solar generator kits
All kitsA power station bundled with a solar panel. Most popular first.
