5500 Watt Portable Generator. Don't let the name fool you. Medium emergency generators (3,000-5,000 watts) may be relatively small, but they pack a good punch.
Unlike smaller camping generators, medium-sized emergency portable generators can simultaneously power multiple survival appliances, including your refrigerator, sump pump, and furnace fan.
Most homeowners simply run the generator outside and string extension cords through an open door or window to the inside appliances.
