Is the PM5000S enough to run a refrigerator and a space heater?

Usually not both at once. Running wattage is 3,800, and a space heater alone can draw 1,500 watts. Run the fridge first, then the heater, and keep total load under 3,800 watts.

Does it produce clean power for laptops and TVs?

Yes. It is an inverter generator with pure sine wave output, which is what sensitive electronics need. Avoid loading it near its limit, since voltage can sag.

How is it different from the PM5000SE?

The SE adds propane and LPG operation and electric start. The PM5000S is gasoline only with a recoil pull start, so the SE is the better pick if you want dual fuel.

Can it be connected to a home transfer switch?

Only through a 120V inlet, since it has no 240V outlet. For a full panel backup you would need a larger dual-fuel or 240V model.

What comes in the box?

The generator, user manual, socket extension bar, funnel, screwdriver, a US duplex plug and a US 3-prong anti-disconnect plug. Oil and fuel are not included.

How long can it run on a full tank?

About 11 hours at 25% load. At half load expect roughly half that, and less under heavy loads.
