About Home Watt Lab
Free tools that tell you what it takes to keep your home running when the power goes out.
Ryan Calloway
Ryan Calloway is the editor of Home Watt Lab. Every number on this site comes from a published source or a stated formula, and each page lists them.
We haven't tested these generators or power stations ourselves, and we don't say we have. We check each model against its manufacturer's published specs and show the date we did it.
How the site makes money
The calculators are free. In time, some links to products may be affiliate links, which pay us a commission at no cost to you. We may also show ads below the calculators, never inside them. Neither affects which models pass your numbers. Affiliate disclosure
Corrections
If a number looks wrong, it matters to us. Each calculator links to its sources so you can check it, and the method page explains every formula.
