| Summary | The DuroMax XP11500EH is a 9,000-watt dual-fuel generator built for homeowners, job sites, and outdoor users who need serious power without fuel limitations. Running on gasoline or propane, it delivers 11,500 peak watts to start large loads like air conditioners, compressors, and welders. The 457cc engine produces enough current to run multiple high-demand devices simultaneously, making it suitable for whole-home backup or extended job site work.
At 224 pounds with wheels included, this unit bridges the gap between portability and raw power. The 8.3-gallon tank and dual-fuel flexibility mean fewer refueling stops on gasoline, or the option to switch to propane for storage stability and cleaner operation. Three-year warranty covers manufacturing defects across the ownership period. | The Powerhorse s4500d is a dual-fuel portable generator offering 4,500 surge watts and 3,600 rated watts, suitable for various applications including home backup and outdoor activities. |
