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.

The Predator 71341 is a 1400-watt gasoline generator built for portable power in situations where you need steady electricity without the weight penalty of larger units. At 60 lbs, it sits at the threshold between grab-and-go portability and genuine stationary capability. The 1400-watt running output powers small job sites, RV setups, and home backup scenarios. Think laptop charging, power tools, small refrigerators, and LED lighting running simultaneously. The 1800-watt starting capacity handles the surge when compressors, pumps, and air conditioners first engage. Gasoline fuel means you refuel at any gas station and operate in remote locations where propane or natural gas lines do not exist.
