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 72899 is a 3500 Watt Super Quiet Inverter Generator designed for efficient and quiet operation, suitable for various applications including RVs.
