| Summary | The RYOBI RY906522 is a gasoline-powered portable generator delivering 6800 running watts and 8500 starting watts, featuring a 420cc OHV engine and a 6-gallon fuel tank for up to 9 hours of runtime at 50% load. | The WEN 56877-CA is a 7000-watt gasoline generator built to handle both steady power and high-demand startup surges. The 9000-watt peak capacity means it can start air compressors, well pumps, and air conditioning units that draw 1.5 to 2 times their running wattage on startup, then settle into continuous operation at 7000 watts. This power band covers most household circuits, power tools, and small job site equipment simultaneously. The 6.5-gallon fuel tank runs for 9 hours at 50 percent load, which translates to roughly 18 hours at 25 percent load for lighter duty cycles. A 2-year warranty backs the unit, giving owners a defined service window for defects. |
