| 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 WEN DF1200X is a 9500-watt running generator built for sustained power delivery across job sites, RVs, and backup power scenarios. Its 12000-watt peak output handles the inrush demands of air compressors, pumps, and heavy tools without voltage sag. Dual fuel capability (gasoline and propane) means you can run on whichever fuel is available or more economical at the time. The 8.2-gallon tank delivers 7.5 hours of runtime at 50 percent load on gasoline, reducing refueling frequency during extended operations. A 2-year warranty covers defects during the ownership window. |
