| Summary | The Powerhorse s15000d is a dual-fuel portable generator delivering 15,000 surge watts and 12,000 rated watts, suitable for emergency home backup, EV charging, and demanding worksites. | 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. |
