Dual Fuel Portable Generators
Dual Fuel Portable Generators: Gas or Propane, Your Choice
A dual fuel portable generator gives you the flexibility to run on gasoline or propane depending on what's available, which matters most during extended outages when gas stations can run dry or propane becomes the more reliable option. Our lineup spans a wide range, from the compact DuroMax XP2300iH at 2,300 watts up through the DuroMax XP28000IH at 28,000 watts, with Cummins Onan and EcoFlow rounding out the selection for buyers who want additional brand options at various price points.
Choosing a Size Across the DuroMax Range
DuroMax makes up the bulk of this collection, spanning from the XP2300iH and XP5500 at the smaller end, suited to camping or light backup, through the XP9500, XP11000, and XP13000HX in the mid-to-large range for home backup, up to the XP16000 and XP28000IH for buyers needing serious continuous output. Several models, including the XP13000HXT and XP15000HXT+, actually extend into tri fuel territory, adding natural gas as a third option alongside gas and propane, worth noting if you have a natural gas line and want that added flexibility beyond standard dual fuel.
Cummins Onan and EcoFlow Alternatives
For buyers wanting a different brand, the Cummins Onan P4500iDF and P5000iDF EFI offer dual fuel inverter technology with remote start, useful if you want to start the generator without physically walking out to it during a storm. The larger Onan 9500DF and P9500DF EFI extend Cummins' dual fuel lineup into higher-output territory. The EcoFlow Smart Generator 4000 offers a dual fuel option built to pair with EcoFlow's battery power stations, giving buyers a hybrid path between fuel-based and battery backup rather than choosing one exclusively.
Frequently Asked Questions
What does the CO Alert feature on DuroMax units actually do?
The CO Alert system uses a built-in sensor to monitor carbon monoxide levels around the generator and automatically shuts the engine down if concentrations reach a dangerous threshold. It's a passive safety feature that works without any manual activation, though running any fuel generator in a well-ventilated area away from windows and doors remains important regardless of whether it includes CO protection.
Is remote start on the Cummins Onan models worth the extra cost?
Remote start lets you start the generator from inside your home rather than walking out to it manually, which is a real convenience during a storm when going outside isn't ideal. For buyers who prioritize convenience and are willing to pay more for it, this feature is worth considering; for buyers focused purely on maximizing output per dollar, a comparable DuroMax unit without remote start often delivers similar wattage at a lower price point. The Cummins 9500 and many of the Duromax models also come with a FREE remote start key fob!
How do I know what size dual fuel generator I actually need?
Add up the wattage of everything you'd want to run simultaneously and compare that against a unit's continuous output rating rather than peak or surge rating. Light use, camping or a handful of essentials, is often covered by 2,000 to 5,500 watts. Home backup covering major appliances typically needs 9,000 to 13,000 watts, while whole-home coverage or heavier job site use may call for the 16,000 to 28,000 watt range this collection tops out at.
