Campgrounds enforce quiet hours and neighbors enforce the rest. Noise is 25% of our scoring for a reason — of the 12 inverter generators we track, these lead on decibels.

Reading dB
A 10 dB gap sounds roughly twice as loud to the human ear. In our table the spread between the quietest and loudest units is therefore not a footnote — it's the difference between a campsite hum and a complaint.
The fine print
Manufacturers quote noise at 25% load from 7 meters away; full load is louder. The number is still the best apples-to-apples comparison available — just don't expect conversation-level quiet at full tilt.
Safety
Carbon monoxide shutoff is 15% of our scoring. It's the feature you hope never activates — and the reason we won't give top marks to a unit without it. Never run any generator indoors or near windows, shutoff or not.
The data
Sorted by rated noise (dB), quietest first. Missing specs show as — and are excluded from that model's score with the remaining weights rescaled. Full formula on the methodology page ↗
