| Summary | The DuroMax XP13000EH is a 10,500-watt dual-fuel generator built to handle serious backup power demands. Running on gasoline or propane, it delivers enough sustained output to power multiple household appliances simultaneously, including refrigerators, water heaters, and air conditioning units during extended outages. The 13,000-watt peak capacity means it can start high-inrush devices like compressors and pumps without strain. This wattage class sits at the threshold between portable and semi-stationary power, making it suitable for homeowners who need whole-home backup rather than just essential circuits. | The NorthStar e9250s is a commercial-grade, portable generator featuring a 420cc OHV EFI engine, delivering 9,250 surge watts and 7,250 rated watts. It boasts Quiet Armor Technology for reduced noise, an electric start with a built-in battery charger, and a multi-function LCD display for monitoring generator functions. |
