GENMAX 2000W Low-Noise Gas Inverter Generator with Eco Mode (GM2000i)

- 1,600W running, 2,000W start
- 34 lb, 60 dBA
- 8 hours at 50% load
Our take
Pick it if you need to lift it into a trunk or up stairs and want enough power for a refrigerator, lights and electronics.
Why it made the shortlist
The GENMAX GM2000i lists 2,000 starting and 1,600 running watts from a 79.7 cc engine at under 3 percent THD, weighs 34 pounds with a sturdy carry handle, and claims noise as low as 60 dBA and 8 hours at 50 percent load on a 1 gallon tank. Its panel has 120V 20A outlets and two USB ports, and it has low oil and overload alarms, a CO detect shutdown, parallel readiness and a 3-year warranty with lifetime support.
It ranks first because it balances weight and output best: 34 lb for 1,600 running watts is about 21.3 pounds per 1,000 watts, and its price of $329.99 is $50.70 above the AIVOLT 1750 for 250 more rated watts. It also states its runtime at a clear load.
What works
- 34 lb for 1,600 rated watts
- Runtime stated at 50% load on 1 gallon
- Three-year warranty with lifetime technical support
- CO detect shutdown and parallel readiness
Watch out for
- 1,600 running watts cannot start an air conditioner
- One gallon tank needs a mid-night refill
- The catch
- Against the Efurden 2800 it costs $30.00 more and is 6 pounds lighter with 400 fewer rated watts.
