| Summary | The DuroMax XP9500iH is a 7,600-watt dual-fuel inverter generator built for whole-home backup and job-site power. Running on either gasoline or propane, it delivers 9,500 starting watts to handle motor inrush demands from air conditioners, well pumps, and power tools. The inverter produces clean 3% THD power, meaning laptops, televisions, and medical equipment run safely without risk of voltage spikes. This is a stationary or semi-portable unit. At 216 pounds, it requires wheels or multiple people to move, making it suited for permanent installation or fixed-location backup rather than frequent relocation.
The fuel flexibility matters in extended outages. Gasoline runs 11 hours at half load before refueling, while propane stretches to 5 hours at the same draw. At quarter load, gasoline delivers 21 hours of runtime, propane 9.5 hours. For homeowners choosing between fuel types, gasoline offers longer intervals between refills, propane offers cleaner storage and no fuel degradation over months. | The Powerhorse 2500i is a portable inverter generator delivering 2,500 surge watts and 1,800 rated watts, featuring a quiet 52dB operation, CO shutdown function, and parallel-ready design for increased power needs. |
