| 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 PREDATOR® 6500 Watt Portable Generator is designed for home backup during emergencies and powering tools at jobsites. It features a 301cc gas engine, GFCI outlets, and CO SECURE® carbon monoxide shutdown for safety. |
