powerstationscompared.com is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com.
In plain terms: when you follow one of our links to Amazon and buy something, Amazon may pay us a small commission. You pay exactly the same price either way.
The ranking on this site is computed from the figures alone — capacity and
continuous output normalised 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.
If a commission ever did influence what we recommend, the honest thing would be to say so here. It does not, and we would rather state that plainly than bury it in a footer.
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.
