Collection: Tri-Fuel & Dual-Fuel Generators

What is a Tri-Fuel Generator? Tri-fuel portable generators, sometimes called Triple-fuel generators, are generators that run on propane, natural gas, or gasoline right out of the box. Natural gas is the most convenient choice of fuel since refueling is unnecessary.
On the other hand, what are Dual-Fuel GeneratorDual-fuel portable generators use two different types of fuel (most often liquid propane and gasoline) at the same time. In comparison, bi-fuel engines use two different types of fuel interchangeably. Switching between fuels is usually done automatically based on which fuel type will be most efficient at that point in time.
These two distinct generators have a wide range of applications depending on your needs. As such, Our Generators offers both tri-fuel generators and dual-fuel generators for sale. Shop below for a diverse selection of high-performing products.
