| Summary | The Energizer eZV8000 is a 6,500-watt inverter generator built around a 420cc OHV 4-stroke engine. This wattage places it squarely in the mid-to-heavy duty range, capable of powering multiple household appliances simultaneously. A typical home refrigerator (600 watts), microwave (1000 watts), and several lights (300 watts) can run together, leaving headroom for power tools or additional devices. The 8,000-watt peak rating handles the inrush demand when motors first spin up. Because the eZV8000 runs on gasoline and includes inverter technology with less than 3% THD, users can safely power laptops, TVs, and other sensitive electronics without risk of damage from power spikes. The 5.5-gallon fuel tank delivers 15.5 hours of runtime at 25% load, meaning a full tank can sustain light-duty operation through an entire workday or camping trip. | The Generac GP3300i is a 2,500-watt inverter generator built for users who need portable, clean power without the weight penalty. At 59.5 lbs, it moves easily between campsites, tailgates, and home backup scenarios. The 3,300-watt starting capacity handles motor-driven equipment, while sub-3% THD protects laptops and phones from voltage spikes. |
