The Yamaha EF2200iS Inverter Generator even comes with a 30-amp RV outlet to keep your camping trips powered up. For heavier-duty applications, Yamaha has designed with Twin Tech, allowing you to connect two EF2200iS Inverters in-line for a rated 30 amps of power.

Yamaha has this model geared toward lighter to mid-duty applications where its compact build and portability can be a real asset. It weighs 55 lbs, takes up 21.9″ x 11.8″ x 18.5″, and features a 1.24-gallon fuel tank. The company states that at 25% of the rated load, the ES2200iS Inverter Generator can run for up to 10.5 hours.
