Duramax Dual Fuel Generators are the perfect solution for those looking to power their home or workspace. The Duramax Generator accepts both propane and gasoline as fuel, which provides flexibility depending on what is more available in your area.

Propane has a longer shelf-life than gasoline and burns clearer without harmful emissions like carbon monoxide. This product averages 20 hours when using propane for fuel with an electric start that can be used if needed, while 8 hours of run time is average when relying solely on gas consumption–giving you plenty of runtime options no matter where you’re located!

The Duramax Dual Fuel Generator generates 69 dB of sound, which is equivalent to normal human conversation. This means it isn’t too loud for a generator its size but still remains an issue when running in close proximity with other generators or near homes and buildings.

This generator operates at 3850 running watts and 4,850 max watts. This is a considerable amount of power that can be used to keep your home appliances going during an outage. For instance, full-sized air conditioners or furnace blowers can both be powered by the gennie, making it a great asset when our lights go out!

The Duramax Dual Fuel Generator is a powerful generator that can provide more power than many other competitors. It’s mobile and has an easy-to-use interface, so you don’t have to be tech-savvy in order for it to work well with your needs!
