Dual fuel generator connected to a propane tank

Best dual fuel generators

A dual fuel generator runs on gasoline or propane, switching with a dial. Propane stores for years without going stale, burns cleaner and is easy to find in 20 lb tanks; gasoline gives a little more power. For emergency backup, that flexibility is hard to beat. We ranked every dual fuel model, open frame and inverter (tri fuel models also appear here).

How to choose

Expect less power on propane

Propane holds less energy per volume than gasoline: most dual fuel units lose about 10% of their output on LP. We show both ratings on each review.

Plan your propane runtime

A standard 20 lb tank holds about 4.7 gallons of propane. A mid-size generator at half load burns through it in roughly 5 to 10 hours. For long outages, a 100 lb tank or several 20 lb tanks make sense. See gas vs propane.

Check the outlets for home backup

For a transfer switch or interlock kit, you want an L14-30R or a 14-50R outlet.

Mistakes to avoid

  • Storing gasoline for months without stabilizer: it gums up the carburetor. Run on propane between outages, or drain the fuel.
  • Using a long, thin propane hose: follow the manufacturer's hose and regulator specs.

Frequently asked questions

Is a dual fuel generator worth it?

For home backup, usually yes: propane stores indefinitely and is available when gas stations are closed after a storm, while gasoline gives full power.

How long will a dual fuel generator run on a 20 lb propane tank?

Roughly 5 to 10 hours at half load for a mid-size unit, depending on its size and the load. The review pages give the manufacturer's runtime on gasoline.

Do dual fuel generators lose power on propane?

Yes, typically around 10%. A 9,500 W unit on gasoline is often rated near 8,500 W on propane.
