| Summary | The DuroStar DS11000DX is a 9,000-watt dual fuel generator built around a 457cc OHV engine with cast iron sleeves. This wattage places it squarely in the home backup and light job site category. On gasoline, it runs 9 hours at half load and 19 hours at quarter load. On propane, runtime drops to 3.5 hours at half load and 7 hours at quarter load, making gasoline the practical choice for extended outages. The dual fuel option gives users flexibility when propane is more accessible or economical, though gasoline delivers longer operating windows per tank. At 74 dB, the noise level sits in the moderate range for this power class, meaning it will be audible but not prohibitively loud in residential settings. The 8.3-gallon fuel tank combined with the quarter-load runtime means users can stretch a single fill to nearly a full day of light operation. | The Westinghouse WGen5300cv is a gasoline-powered generator with a rated wattage of 5300 watts and a peak wattage of 6600 watts. It is designed for portable use with features suitable for home backup and RV applications. |
