Gasoline and dual-fuel (gasoline and propane) inverter generators up to about 7,500 W sold new in the US for portable use. Conventional non-inverter generators, home standby generators, battery power stations and measured noise, fuel-economy or reliability rankings are outside this catalogue. This catalogue gives no electrical connection, transfer switch or installation advice; follow the manufacturer's manual and a qualified electrician where the manual requires one.

Questions to check before buying	Champion's 64 dB(A) figure has no stated load or distance, so it is not comparable with figures that state them. Champion does not state CARB or California status for 201321; confirm with the seller before ordering for use in California. The 92.6 lb weight basis (dry, with battery or with oil) is not stated.	The 52 dBA figure has no stated load or distance; as low as wording suggests the lightest operating condition, but Westinghouse does not say so. The propane cylinder size for the 22 h propane run time is not stated. The iGen5000DFc EFI, iGen5000DF without CO sensor and iGen5000DFcv are separate listings with different figures and are not covered by this record.
