Who this review is for
This page stays at a list price of $300 or less. A phone, a light, and a laptop are realistic on the smaller ones. A cooler, or a short outage at home, needs one of the larger ones in this price. Decide what you need to run, and for how long, before you look at the brand.

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.
