Useful first. Clear about our limits.

WattReady Guide aims to make backup power decisions easier to understand. We favor transparent calculations, direct links to authoritative sources and practical explanations over unsupported promises.

Research and review

We prioritize original explanations, manufacturer documentation for product-specific specifications, and government or recognized safety sources for safety guidance. We identify illustrative assumptions and avoid representing a general example as a universal fact.

Corrections and updates

We update a page when its substance changes and show the reviewed date. We do not change dates solely to make a page look fresh. Readers can flag errors through the contact page.

Commercial relationships

Some links may be affiliate links in the future. If a link earns a commission, we will identify it near the recommendation and explain the relationship on our affiliate disclosure page. Compensation does not affect a calculator’s inputs or results.
