The DuroMax XP13500iH dual fuel inverter generator is a practical choice when you want substantial home backup power with the option to run on gasoline or propane. You get up to 13,500 starting watts and 10,500 running watts on gasoline, 120/240V output, and inverter power with less than 3% total harmonic distortion.
This model keeps the fuel choice simple. Fill the 8-gallon gasoline tank or connect a propane cylinder using the included hose and regulator. Electric push-button starting, an included remote, and a recoil starter give you several ways to get it running. The XP13500iH is the dual fuel model; choose the XP13500iHT tri fuel inverter generator if you need natural gas capability.
Why Choose the DuroMax XP13500iH?
- Gasoline or propane: Switch between gasoline and propane without buying a separate conversion kit.
- Clean inverter output: Less than 3% THD for equipment that calls for clean AC power, including many electronics and appliance controls.
- Home backup connections: A 50A 14-50R outlet and 30A L14-30R outlet provide options for a compatible transfer switch or generator interlock installation.
- Remote and electric start: Start using the included remote or front-panel push button, with recoil starting also available.
- Built for regular use: A 550cc OHV engine, 100% copper windings, and demand-based variable idle.
- Easy to monitor: Digital voltage and hour displays, a fuel gauge, and a battery tender with charging port.
- Protection features: CO sensor shutdown and automatic low-oil shutdown.
- Manufacturer warranty: Five-year residential parts warranty; one year for commercial or unusually heavy use, subject to DuroMax terms.
Best Use Cases
- Home outage backup: Keep selected household circuits running through a correctly installed transfer switch or interlock. Add up running loads and motor-starting requirements before choosing what to power.
- RV and travel power: Supply compatible 120/240V RV equipment using the appropriate connection and load limits.
- Jobsite power: Run compatible tools, chargers, and lighting where utility power is unavailable.
- Stored-fuel emergency preparation: Keep propane available as an alternative when gasoline is harder to find during an outage.

Frequently Asked Questions
How many watts does the XP13500iH produce?
On gasoline it supplies 13,500 peak watts and 10,500 running watts. On propane it supplies 12,750 peak watts and 10,000 running watts. Peak output covers short starting surges; use running output when planning continuous loads.
Does the XP13500iH run on natural gas?
No. The XP13500iH runs on gasoline and propane. For factory natural gas capability, see the DuroMax XP13500iHT.
Can it power my whole house or central air conditioner?
It can support a substantial set of household loads, but that depends on the fuel, appliance starting requirements, and what runs at the same time. Check air conditioner starting current and other large loads rather than relying on square footage or starting watts alone. A licensed electrician should install the appropriate transfer equipment.
Is the inverter output suitable for sensitive electronics?
DuroMax specifies less than 3% THD. That makes it a useful option for many electronics and appliances requiring clean AC power. Check the power requirements of your equipment.
How long does it run?
The published gasoline ratings are 19.9 hours at 25% load and 10.8 hours at 50% load. On propane, the ratings are 16.9 hours at 25% load and 9.2 hours at 50% load using a 40 lb tank. Actual runtime varies with load, fuel conditions, and temperature.
Is it automatic standby backup?
Remote starting does not make this an automatic standby generator. Home backup requires compatible transfer equipment and proper operating procedures.
Can this model ship to California?
No. DuroMax lists this model as EPA certified but not CARB certified or 50-state compliant.
What is the warranty?
The current owner’s manual provides a five-year parts warranty for residential use and one year for commercial or unusually heavy use. Coverage is for the original purchaser and is non-transferable. See the manufacturer warranty document for coverage, exclusions, and service requirements.
Can I charge a home battery system through the DC output?
The current manual describes a 58V bulk-charge output for compatible 48V and 52V home energy storage systems. Compatibility depends on the battery chemistry, BMS, charging limits, and inverter. Lead-acid systems require an external controller. Have a qualified installer confirm the connection; this is not a universal plug-and-play connection to every home battery.
