What is a dual fuel generator?

A dual fuel generator runs on gasoline or propane through the same engine. Propane is easy to store and burns cleaner; gasoline is widely available and usually gives a little more power.

Gasoline tank
Propane cylinder hookup
Fuel selector
120/240V outlets

Why choose dual fuel generators from Generator Hubs?

Two fuels

Use whichever you have during an outage.

Propane stores well

No stale fuel after months in storage.

Wide range

From camping sizes to whole-home models.

Manufacturer specs

Every figure comes from the maker’s spec sheet.

Brand-new products

Genuine, unused, in the original packaging.

Your home backup solution

Typical running watts: refrigerator 700 W, sump pump 1,050 W, furnace fan 800 W, well pump 1,000 W, central AC 3,800 W.

FAQ

Gasoline or propane: which gives more power?

Gasoline usually gives slightly more watts. Each product page lists the ratings published by the manufacturer.

How many watts do I need?

Add up the running watts of everything you want to power at the same time, then add about 25% headroom for motors that surge when they start. Essentials usually need 5,000–8,000 W; a whole home with central AC often needs 12,000 W or more.

Can I connect a generator to my house?

Only through a transfer switch or interlock kit installed by a licensed electrician. Never backfeed power through a wall outlet.

Can I run a generator indoors or in a garage?

No. Run fuel-powered generators outdoors, at least 20 feet from doors, windows and vents. CO alert shutoff is a safety backup, not permission to run indoors. Battery power stations can be used indoors.

Which models can ship to California?

Only CARB-compliant models can be sold in California. Each product page says whether a model is CARB compliant.

How are large generators delivered?

Large generators ship by freight. Delivery terms are shown on our shipping page and confirmed before dispatch.

What is your return policy?

You have 30 days from delivery to return unused equipment. Returns are free: we send you a prepaid return label.
