How these picks were made
Picks are editor-selected from this index’s US-market portable-generator set, prioritizing running output and CO-shutdown safety for whole-home backup. Each generator’s exact specs, provenance, and documented caveats (for example, whether a CO sensor is actually present) live on its detail page.
