At 5.5kW (5,500-watt) the generator provides enough electricity to run most household essentials during a power outage or to power recreational vehicles (RVs) and job sites. It generally supplies about 45 to 23 amps at 120/240 volts, allowing you to run critical combinations like a refrigerator, a sump pump, lights, a microwave, and a window air conditioner or furnace fan simultaneously.
