| Summary | The Briggs & Stratton 30737 is a 5000-watt gasoline generator built for homeowners and job site operators who need extended runtime without constant refueling. With 5000 running watts and 6250 peak watts, this unit can power a refrigerator, multiple lights, and power tools simultaneously, making it suitable for emergency backup or outdoor work. The 7.5-gallon fuel tank delivers 12 hours of runtime at half load, which means a full day of operation before refueling becomes necessary. This is a stationary-duty machine. At 184 pounds, it requires wheels or multiple people to move, so placement matters before startup. | The Powermate PM9400E is a portable generator offering 9,400 starting watts and 7,500 running watts, equipped with a Generac 420cc OHV engine and an 8-gallon fuel tank, providing up to 13 hours of runtime at 25% load. |
