Every model is compared on the same six checks. The numbers are the brand's specs and the list price on the day we checked. A battery test appears only when another site has published one. The full rules are on How we review.
Questions
Why do some models have no price?
We only show a price after we've checked it on the brand's site and noted the date. No price means we haven't confirmed one. It doesn't mean the station is free.
Did you test the watt-hours?
No. The watt-hour number in the specs is the brand's rating. When another site has published a usable watt-hour test and a link, that row is separate. Two labs can list different numbers.
Is there a score?
Each model page shows a spec index from 7.0 to 10. It weights capacity, continuous output, weight, and the US list price per watt-hour. The formula is on How we review.
