How We Rate
Every product on StandbyWatts is evaluated against a structured, weighted rubric built around what actually matters when the power goes out: runtime, real power output, noise level, how easy the unit is to set up and move, and how it protects your home and family.
Our research process pulls real product specifications, published manufacturer data, and patterns in verified Amazon buyer reviews. We do not claim hands-on lab testing — our assessments are editorial judgments based on that research, not measurements from a physical unit in our possession.

We never accept payment for placement or a favorable review. A product's affiliate commission rate is never a factor in its score or ranking — low-scoring products are excluded from our top picks regardless of commission rate.
