Clean Energy

Note: The Champion 100302 is essentially a 100573 with the exception of the wheel kit and electronic starter generator. So you just get a recoil start and must lift the generator to transfer it. It isn’t very heavy, as the elimination of the wheel kit, battery, and electric starter reduces the weight from 97 to 81 pounds.

Lifting this, however, is not something I would advocate for older persons or ladies. Furthermore, the 100302 lacks flip-up covers for its outlets.
