Summary
The DuroStar DS10000E is an 8,000-watt gasoline generator built for users who need sustained power across multiple simultaneous loads. With 10,000 peak watts and an 8.3-gallon fuel tank, this unit can run a central air conditioning system, refrigerator, and several power tools at the same time, making it suitable for whole-home backup during outages or powering an active job site. The 439 cc OHV engine with cast iron sleeve delivers the raw output needed for construction equipment and heavy appliances without inverter complexity. At 218 pounds with wheels included, this is a stationary power solution that moves when needed but stays put during operation. The three-year warranty and EPA/CARB compliance signal DuroStar's commitment to durability and emissions standards across all 50 states.
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.
