The FIRMAN T09275 Tri-Fuel Portable Generator delivers serious performance with the flexibility to run on gasoline, propane (LPG), or natural gas (NG)—giving you control no matter the situation. Producing up to 11,400 starting watts and 9,200 running watts on gasoline, this high-capacity generator is built for home backup power, demanding job sites, farms, and large outdoor events. At its core is a heavy-duty 459cc FIRMAN engine paired with a 9-gallon fuel tank, delivering up to 11 hours of runtime at 50% load. Electric start ensures quick, effortless operation, while the rugged design and cast iron sleeve provide long-term durability under heavy workloads.

When paired with a transfer switch, the T09275 serves as a powerful portable alternative to a whole-home standby generator—ideal for severe weather, extended outages, or emergency preparedness. Fuel flexibility meets dependable output with 11,400 starting / 9,200 running watts on gasoline, 10,400 / 8,300 watts on propane, and 8,650 / 6,900 watts on natural gas.

The generator delivers 120/240V power through a versatile outlet panel that includes a 120V 20A GFCI duplex (5-20R) for household needs, a 120V 30A twist-lock (L5-30R), a 120/240V 30A twist-lock (L14-30R), and a 120/240V 50A outlet (14-50R) capable of supporting high-demand appliances and equipment.
