Champion Inverters boast a unique feature with a digital 15-second power delay, which allows sensitive equipment to be left plugged in on start-up & shut down, a component, unlike any other Generator. Another outstanding feature is the start-up current. It has a special millisecond peak current of 15.8 amp which is ideal for RV, motor homes and caravans, allowing their equipment to start up without tripping or overloading the generator (especially running A/C units or similar).
