Gasoline vs propane: which fuel should you use?
The DuroMax XP12000EH gives you two fuel choices, which is one of its biggest strengths. Gasoline gives you the highest output, while propane is cleaner to store and can be easier to keep ready for emergencies.
- Maximum available output
- 12,000 starting watts
- 9,500 running watts
- Better support for heavier startup loads
- Traditional fueling with the onboard tank
- Cleaner long-term fuel storage
- Less worry about stale gasoline
- Easy cylinder swapping during emergencies
- Backup fuel flexibility
- Lower output but still strong home-backup capability
Can the DuroMax XP12000EH power a house?
A generator with 9,500 running watts can power many important home circuits, and the DuroMax XP12000EH is clearly aimed at that type of use. With a properly installed transfer switch or interlock setup, it can support essentials like refrigerators, freezers, lights, sump pumps, furnace blowers, well pumps, internet equipment, TVs, and selected larger appliances depending on their starting watt requirements.
- Home backup during outages
- Refrigerator and freezer power
- Sump pump and well pump support
- Gas furnace blower
- Lights, fans, TVs, and internet
- Larger RV loads
- Heavy-duty tools and jobsite use
- Central air conditioning
- Electric water heaters
- Electric dryers
- Large electric ranges
- Multiple high-draw appliances at once
- Whole-house loads without load management
DuroMax XP12000EH vs tri-fuel generators
The XP12000EH is a dual fuel generator, so it runs on gasoline or propane. It does not run on natural gas out of the box. If you want natural gas, propane, and gasoline in one generator, compare it with a tri-fuel model instead.
If you want natural gas support, compare the DuroMax XP12000EH with the Champion 201161 tri-fuel generator.
If the XP12000EH feels bigger than you need, the WEN 56475 is a more modest electric-start portable generator worth comparing.

- Point exhaust away from people and buildings.
- Use heavy-duty outdoor-rated cords when needed.
