Summary
The ECHO EGi-1200 is a 1000-watt inverter generator built around a 60cc OHV 4-stroke engine that runs on gasoline. This wattage class powers small appliances, laptops, power tools, and camping equipment without the noise footprint of conventional generators. The inverter technology means the power output stays clean and stable, which protects sensitive electronics like phones and laptops from voltage spikes that can cause permanent damage. At 30 pounds, this unit sits at the lightweight end of the portable generator spectrum, making it genuinely grab-and-go for one person. The 0.69-gallon fuel tank and 5.2-hour runtime at 50% load define a refueling cycle measured in hours, not days, so users planning extended trips need to account for fuel stops or carry extra cans.
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.
