| Summary | The Firman P06701 is a 6700-watt gasoline generator built around a 389cc OHV 4-stroke engine with a cast iron sleeve. This wattage class powers essential home appliances, job site tools, and outdoor event equipment simultaneously. The 8-gallon fuel tank stretches runtime to 12 hours at half load, meaning users refuel once per day under moderate use rather than every few hours. At 74 decibels, the noise level matches a vacuum cleaner, loud enough to require distance from neighbors but typical for this power class. The recoil starting system is mechanically simple and reliable, though it demands physical effort on cold mornings or after storage. | 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. |
