How we make money

Outage Hours is free to read. Some links to stores may earn us a commission when you buy, at no extra cost to you.

Commissions never change the ranking. The order comes from the formula on the method page: hours from measured or estimated capacity, then battery size. A unit that can't last the night stays in the table with the reason.

No brand pays to be listed or to rank higher, and no brand sees our pages before they go live.

The "Check Amazon" buttons open an Amazon search for that model.
