GENMAX Portable Generator,2200W Ultra-Quiet Gas Engine

- 2200 starting watts, 79.7cc
- 41.8 lb, as low as 58 dBA
- CO shutdown, 30A outlet
Our take
A clearly specified, quiet generator with an RV outlet. Check your loads against running watts.
Why it made the shortlist
The GENMAX GM2200i lists 2200 starting watts from a 79.7cc four-stroke engine with inverter output. It weighs 41.8 lb, runs as low as 58 dBA and states up to 6 hours at 50 percent load from a 1 gallon tank.
It names two 120V/20A outlets and a 120V/30A outlet, which suits an RV hookup, and adds a CO shutdown sensor, low oil and overload alarms.
It suits car campers and small-trailer owners who want a quiet, light generator with a clear safety package. Economy mode trims fuel use at light loads.
What works
- Names a 120V 30A outlet
- CO detect shutdown sensor
- Low noise figure stated
- Economy mode saves fuel
Watch out for
- 2200 is a peak figure
- Running watts are lower
- The catch
- The 2200 figure is starting watts, so running watts are lower.
