The Champion Power Equipment 100538 is a wonderful generator for anybody seeking a dependable and powerful model. It has a maximum power output of 9,375 watts and a rated output of 7,500 watts. The engine is a 420cc, 4-stroke, single-cylinder, air-cooled design. It also has a 5.7-gallon fuel tank. At 50% load, the run time on this generator is 8 hours. 120/240V 30A Locking (L14-30R), 120/240V 50A (14-50R), and two GFCI 120V 20A Duplex (5-20R) outlets are included. The only disadvantage of the generator is that it has a rather loud engine of 74 dB(A), which may wake up young children and elders. Moreover, the generator comes with a three-year warranty from the manufacturer.
