Our Methodology

A clearer way to compare backup power

Every guide compares products against the same seven criteria, weighted and combined into a single score. We research published specifications, manufacturer documentation, and patterns in verified buyer feedback rather than claiming to have tested every unit ourselves.

StandbyWattsdoesn't accept payment for placement or scores. Our affiliate income depends on recommending products people are actually happy with when the power goes out, so honest evaluation is in our direct interest.

25%

Runtime & Fuel Efficiency

20%

Power Output & Capacity

Real running and starting watts, not just the number printed on the box.

15%

Noise Level

Decibel rating and how disruptive it is to run near a house or campsite.

15%

Setup & Portability
