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 Honda EM6500SX is a 6500-watt generator equipped with an electric start, Bluetooth capability, and CO-MINDER for advanced carbon monoxide detection. It offers a long run time of up to 9.8 hours and can power a variety of household appliances.
