How many watts can it run on propane?

It delivers 4,275 running watts and 5,225 peak watts on propane, versus 4,500 running and 5,500 peak on gasoline. That is enough for a fridge, furnace blower and lights, but not a central AC.

Does it have a CO shutdown?

Yes. The CO Alert sensor shuts the generator off automatically when carbon monoxide reaches a set level. It is a safety backstop, not a substitute for running the unit outdoors.

How long does it run on a tank?

About 9 hours at 50% load on gasoline and roughly 19 hours at 25% load. Propane runtime is shorter, around 15 hours at 25% load from a standard tank.

Can it power a house transfer switch?

Yes, through the L14-30R 120/240V twist-lock outlet. A 4,500-watt running output supports a few essential circuits, not a whole house.

What comes in the box?

The generator, a 4-foot propane hose and regulator, a 12V SLA battery, and a wheel and handle kit with 8-inch metal-hub wheels.

Is it hard to start in cold weather?

Electric start handles most cold starts, but the recoil pull can be stiff below freezing. Store it out of the weather and use fresh fuel.
