Our take on the Firman Dual Fuel Portable Generator 7125/5700W Electric Start

The Firman dual fuel portable generator delivers 7125 starting watts and 5700 running watts on either gasoline or propane, so you can switch fuels when one runs out. It has an electric start with a recoil backup, an 8-gallon tank that runs up to 12 hours at half load, and a 439cc engine with a cast iron sleeve and low oil shutoff. Flat-free 10-inch wheels and a folding handle make it movable for a unit this size. It suits homeowners who want whole-home backup or job-site power without depending on one fuel, though it is heavy and loud like most open-frame generators in its class.

Questions and answers

Does it really make the same watts on propane as on gasoline?
Firman rates it at 7125 starting and 5700 running watts on both fuels. In practice, propane output can sag in cold weather as tank pressure drops.
How long can it run on a full tank?
Up to 12 hours at 50% load on the 8-gallon gasoline tank. Propane run time depends on the size of the tank you connect.
Can it power a house through a transfer switch?
Yes, 5700 running watts can carry a transfer switch with selected circuits such as a furnace, fridge and lights. It will not run a whole house with central air.
What comes in the box?
The generator, an engine oil bottle, an oil funnel, a spark plug wrench, two double open-ended wrenches and an LPG regulator with hose holder.
Does it have carbon monoxide shutdown?
No. This model has low oil shutoff but no built-in CO shutdown, so run it outdoors and away from windows and doors.
How do I start it?
Use the electric start button after setting the fuel valve and choke. The recoil pull cord is there as a backup if the battery is low.
