Our take on the Firman T12071 Tri-Fuel 12000W/15000W Portable Generator

The Firman T12071 is a large portable generator that runs on gasoline, propane or natural gas, so you can pick whichever fuel is on hand during an outage or on a job site. It is built around a 12000W gasoline rating and 15000W peak, with lower output on propane and natural gas. That tri-fuel flexibility is its main edge over single-fuel rivals of similar size, which lock you into gasoline. It suits homeowners backing up a house and contractors running heavy tools, but it is a big, loud, gas-engine machine, not a quiet inverter unit.

Questions and answers

Can it really run on three fuels?
Yes. It accepts gasoline, propane and natural gas, and you switch fuels at the connection point. Output is highest on gasoline and lower on the two gases.
Can I use it for whole-home backup?
It has enough output for a transfer-switch hookup covering major circuits, but not every appliance at once. A licensed electrician should size and install the connection.
Why can't it ship to California?
It is not CARB-approved, so it cannot be sold or shipped into California. Buyers elsewhere should still check local rules on generator use.
How loud is it?
It is an open-frame generator, so expect noticeably more noise than a closed inverter unit, particularly under heavy load. Place it away from windows and doors.
What maintenance does it need?
Regular oil changes, spark plug checks and fuel-system care, plus exercising it under load now and then. Propane and natural gas avoid gasoline going stale in the tank.
