Champion generators are in a league of their own with regards to engine technology and features, all champion engines are designed, engineered and tested in the most demanding environments and can be proved by watching the testing videos on the CPE website. The main outstanding feature on a champion inverter is the delay stop allowing equipment to stop running or power down so no power surge applies and the second outstanding feature is the start-up current it has a special peak current of 15.8amp for a millisecond that is ideal for RV, motor homes and caravans allowing equipment to start up without tripping or overloading the generator especially running A/C units or similar. They also have a smart charge option that will charge the battery directly from the mains limiting power loss to the battery.
