If the truth be know the Champion, Predator and other inverter generators made in China are most likely built in the same plant. Just a guess. The main difference between Honda/Yamaha and Champion is the motor. Champion has a smaller displacement and the cylinder is not sleeved. For intermittent/occasional use the Champion/China generators will do the job very well. For long term/everyday use I would go with Honda/Yamaha. The Champion with the smaller displacement motor must run at higher RPM to generate the same horse power as the Honda/Yamaha.
