| 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 Genmax GM6000iED is a 5,250-watt dual-fuel inverter generator that handles mid-range backup loads like refrigerators, window air conditioners, and sump pumps simultaneously. Dual-fuel capability lets users switch between gasoline and propane based on availability or storage preference, a practical advantage during prolonged outages. Inverter technology delivers clean power below 3% THD, making it safe for laptops, smartphones, and microprocessor-driven devices without risk of voltage spikes that degrade circuits over time. |
