About

OutageMath answers one question well: how long will a power station run the things you care about?

Manufacturers publish capacity and output figures, but turning those into “will this keep my fridge and CPAP going overnight?” takes math most people don't want to do in the middle of an outage. So we built calculators that do it, and a database of 54 models to run them against.

Who runs it

OutageMath is built and run by Hicham M., a developer. He writes the calculators, maintains the model database and edits the guides, with AI help for code, research and drafts. You can reach him at hello@outagemath.com.

How we work

• We calculate. We don't claim to lab-test. Our numbers come from published specifications and formulas we publish in full.
• We cite sources. Every model page links to the manufacturer documents its specs came from, and we note when official sources disagree.
• We include every model, whether or not we earn anything from it. Rankings and “best fit” results come from the specs only.
• We fix mistakes. Spot an error or an outdated spec? Email hello@outagemath.com.

How we use AI

AI helps write code, gather specs and draft text. The appliance pages and guides were rebuilt in October 2026 around primary sources, and the model specs are being checked against their sources by hand. The details are on How we use AI.

How we make money

Some links to retailers are affiliate links: if you buy through them, we may earn a commission at no cost to you. The site may also show ads. Neither affects our calculations. Details are in our affiliate disclosure.
