| Summary | The Energizer eZV4800 is a 3,600-watt inverter generator built on a 223cc 4-stroke engine. This wattage class handles mid-range household loads: refrigerators, window air conditioners, power tools, and multiple devices simultaneously. The 78-pound weight and 18 x 17 x 21 inch footprint make it portable enough for job sites and camping trips, yet substantial enough to deliver real power without constant refueling. Gasoline fuel means no special storage concerns, and the inverter output protects laptops, phones, and televisions from voltage spikes. | The Predator 73422 is a gasoline-powered generator rated for 2000 running watts with 2500 starting watts. That combination sets it up to handle steady electrical loads while also giving extra headroom for devices that draw more power when they first switch on. |
