Summary
The DuroStar DS13000X is a 10,500-watt gasoline generator built to handle whole-home backup power and job site demands. With 13,000 peak watts and a 500cc OHV engine, this unit can run a full refrigerator, multiple air conditioning units, and power tools simultaneously. The 8.3-gallon fuel tank stretches runtime to 17 hours at 25% load, meaning users can maintain power through an entire night without refueling. At 50% load, the 8.5-hour runtime covers a typical workday, making this suitable for both emergency preparedness and extended outdoor use. The DS13000X includes both recoil and electric start, so users avoid the frustration of pulling a cord in cold weather or after long storage. A 5-year warranty backs the unit, which is 60% longer than the 3.1-year industry average for this wattage class. The combination of power output, fuel capacity, and starting convenience positions this generator as a practical choice for homeowners and contractors who need reliable, extended-runtime power without the complexity of inverter technology.
The Powermate PM7500 is a versatile portable generator offering 7500 starting watts and 6000 running watts, suitable for outdoor events, DIY projects, or emergency backup power. It features Dual Fuel functionality, allowing operation on gasoline or LP gas, and includes COsense® technology for carbon monoxide protection.
