| Summary | The Firman H03655 is a 3,650-watt dual-fuel generator built around a 208 cc OHV 4-stroke engine with a cast iron sleeve. Running on gasoline, it delivers 4,550 starting watts and 3,650 running watts. Switch to propane and output drops to 4,100 starting watts and 3,300 running watts. This power level runs a refrigerator, microwave, window air conditioner, or multiple power tools simultaneously. The dual-fuel flexibility means you can operate on whichever fuel is available, a practical advantage during extended outages or when propane storage is more convenient than gasoline.
At 67 dB at quarter load, the H03655 operates quietly enough for residential neighborhoods without disturbing neighbors. The 5-gallon tank delivers 14 hours of runtime at 50 percent load on gasoline, translating to roughly one full day of moderate use before refueling. The RV-ready configuration and included wheel kit position this unit as a go-anywhere power source for camping, job sites, and home backup scenarios. | The Westinghouse WGen3600cv is a portable gas-powered generator designed for RV use and home backup power. It offers 3,600 running watts and 4,650 peak watts, powered by a 212cc 4-Stroke OHV Westinghouse Engine. The generator features a TT-30R RV outlet, providing up to 14 hours of run time on a 4-gallon fuel tank at 50% load. It includes safety features such as automatic low oil shutdown, automatic voltage regulation, overload protection, and a carbon monoxide (CO) sensor with automatic shutdown. |
