powerstationscompared.com is currently not part of any affiliate program — neither Amazon's nor anyone else's. Links to Amazon on this site pass through our own click counter (see Privacy) and carry no referral tag. We earn nothing when you follow one or buy something.
If that ever changes, it will say so on this page and in the note next to the links, from the day it applies.
The ranking on this site is computed from the figures alone — capacity and
continuous output normalized within each size class, battery chemistry, weight,
and the smoothed customer rating. That calculation lives in a single file,
scoring.js, and it does not know what any product pays. No
manufacturer has paid for placement, sent us a unit, or reviewed this page
before publication.
We do not test these units. Every specification comes from the manufacturer's own published listing, and where a manufacturer does not state a figure, we leave it blank rather than estimate it. That is a real limitation and you should weigh it accordingly — a manufacturer's own number is a claim, not a measurement.
