| Summary | The Firman P08008 is an 8,000-watt gas generator built for job sites, emergency backup, and outdoor events where sustained power matters more than portability. At 8,000 running watts and 10,000 peak watts, this unit can run a refrigerator, microwave, and power tools simultaneously, or handle the electrical load of a small RV. The 439cc cast-iron-sleeve engine burns gasoline, a fuel readily available at any gas station, and runs for 12 hours at half load on an 8-gallon tank. This runtime window means a single refueling cycle covers an overnight power outage or a full day of outdoor work. | The NorthStar c15000s is a commercial-grade portable generator powered by a Honda GX690 OHV engine, delivering 15,000 surge watts and 13,500 rated watts. It features Quiet Armor Technology for reduced noise, a built-in battery charger/maintainer, and carbon monoxide detection with automatic shutdown for enhanced safety. |
