| Summary | The Firman T12071 is a 12,000-watt tri-fuel generator that runs on gasoline, propane, or natural gas. On gasoline, it delivers 15,000 starting watts and 12,000 running watts from a 760cc V-Twin engine with cast iron sleeves. This wattage handles most household circuits simultaneously, powering refrigerators, air conditioning units, well pumps, and power tools without strain. The tri-fuel design eliminates the need to choose between fuel sources. Users in areas with natural gas lines can tap into permanent fuel supplies. Propane users gain the ability to store fuel long-term without degradation. Gasoline remains the highest-output option for maximum starting power during heavy load surges.
The 13.3-gallon fuel tank delivers 11 hours of runtime at 50 percent load on gasoline, meaning users can power a job site or home backup through a full work day or overnight without refueling. Propane cuts running watts to 11,000 and natural gas to 10,000, trading some capacity for fuel flexibility. The copper windings and low THD under 5 percent protect sensitive electronics like laptops, medical equipment, and modern televisions from voltage spikes. A 3-year residential warranty covers defects across all three fuel modes. | The Predator 13,000 Watt Tri-Fuel Portable Generator offers versatile fuel options, including gasoline, propane, and natural gas, making it suitable for emergencies, jobsites, and home backup. It features a remote start capability and CO SECURE technology for enhanced safety. |
