| Summary | The Yamaha EF7200D is a robust and economical generator, delivering a maximum output of 7200 watts and a rated output of 6000 watts. It features a durable 358cc OHV engine, providing up to 8 hours of continuous operation at full load. Designed for both home backup and professional use, it includes a wheel kit for portability and a digital hour meter for maintenance tracking. | The Cat RP5500 is a 5500-watt gasoline generator built for homeowners, contractors, and outdoor enthusiasts who need reliable backup power without the complexity of larger units. This wattage tier handles most household circuits simultaneously, meaning you can run a refrigerator, well pump, and power tools at the same time, but not your entire home's air conditioning system. The 6875-watt peak capacity gives it the muscle to start high-inrush devices like compressors and sump pumps without stalling. Because the RP5500 runs on gasoline, fuel is available at any gas station, eliminating the supply chain friction of propane or diesel models. The 7.9-gallon tank paired with 15-hour runtime at half load means you refuel roughly once per day under typical use, not every few hours. |
