Summary
The DuroMax XP9500iHT is a tri-fuel generator with a rated wattage of 7500 watts and a peak wattage of 9500 watts. It features multiple outlets and advanced starting options.
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.
