DuroMax XP12000EH 12,000-Watt Dual-Fuel Portable Generator

Powerful Gasoline and Propane Backup with Electric Start, MX2 Technology, and Heavy-Duty Portability

Stay prepared for unexpected outages and demanding projects with the DuroMax XP12000EH Dual-Fuel Portable Generator. Delivering 12,000 starting watts and 9,500 running watts, this heavy-duty generator is designed to power compatible household appliances, selected air-conditioning systems, RV equipment, and high-amperage power tools.

Powered by a robust 457cc OHV engine, the XP12000EH offers dual-fuel flexibility, allowing operation on gasoline or propane. Its convenient electric-start system makes startup simple, while a recoil-start backup provides an alternative if the starting battery is drained.

Designed for practical operation at home, on jobsites, and at campsites, this generator features MX2 Technology, idle control, individual circuit breakers, low-oil shutdown, and a noise-reducing muffler with a built-in spark arrestor. Solid-fill tires and high-leverage handles further improve portability across suitable terrain.

Key Features

12,000 Starting Watts and 9,500 Running Watts

Deliver substantial portable power for compatible household appliances, lighting, refrigerators, selected air-conditioning equipment, and high-amperage tools. Always account for starting surges and the combined running wattage of connected devices.

Dual-Fuel Technology

Choose between two fuel sources based on availability and operating requirements.

• Gasoline: A convenient option for portable generator use.


• Propane (LPG): An alternative fuel source when a compatible propane supply is available.

The source description states that propane can extend fuel life. Actual runtime and output depend on the fuel used, connected load, and operating conditions.

Powerful 457cc OHV Engine

The 457cc overhead-valve engine is designed to provide the power needed for demanding residential and worksite applications.

Convenient Electric Start with Recoil Backup

Start the generator using the electric-start system. If the starting battery is drained, the recoil-start system provides an alternative starting method.

MX2 Technology

MX2 Technology is designed to maximize the available power from the generator's 120V receptacles. It allows operation in either of the following configurations, according to the supplied description:

• 120V and 240V operation simultaneously


• 120V-only operation using the available power at 120V

This feature can be useful for compatible RV equipment and other 120V appliances. Verify the manufacturer's instructions and outlet ratings before use.

Idle Control

Reduces engine speed when electrical demand is low, helping conserve fuel and reduce noise during intermittent use, such as on jobsites.

Low-Oil Shutdown

Automatically shuts down the engine when oil levels become too low, helping protect the engine from damage.

Fully Featured Power Panel

The power panel includes a selection of household and higher-amperage outlets, individual circuit breakers, a voltmeter, and 12V DC battery-charging posts.

Noise-Reducing Muffler with Spark Arrestor

The oversized muffler is designed to reduce operating noise. Its built-in spark arrestor helps limit the discharge of sparks, making it suitable for locations where spark-arrestor equipment is required, subject to local rules and applicable restrictions.

Heavy-Duty Portability

Move and position the generator more conveniently with its solid-fill tires and high-leverage handles.

• Tires designed to resist going flat


• High-leverage handles for easier movement


• Durable construction for demanding applications
