    Top-of-the-line DuroMax Performance

    Using its robust DuroMax core engine, the XP4850HX punches in a strong 4,850 watts of maximum power, providing more than enough to run small and large appliances, heavy-duty power tools, lights, and AC units.

    By swapping aluminum for copper windings, the DuroMax XP4850HX benefits from better heat conduction preventing the wires from overheating and thus keeping them running for years to come.

    Dual Fuel Technology

    To allow even greater convenience, the 4,850-watt portable generator supports both gasoline and liquid propane. Using the front-facing fuel input switch, you can choose which source to pull from in seconds.

    To save fuel and money, the idle control feature automatically lowers the RPM of the engine when not in use. In addition, the automatic voltage regulator raises tolerance against power surges and prevents voltage spikes, keeping the engine safe.

    CO Alert

    The all-new DuroMax CO Alert feature now detects when carbon monoxide levels are unhealthy and automatically shuts down the engine to prevent health issues.

    You can work, enjoy a nice camping trip, and share a nice meal with no worries at all.


    By following rigorous guidelines from the Environmental Protection Agency and California Air Resources Board, the DuroMax XP4850HX is both EPA and CARB-approved, therefore making it the perfect option for eco-conscious users.

    By cutting toxic fumes and hazardous emissions by half, the dual fuel portable generator remains the perfect solution for outdoor use, especially since it only weighs in at 129lbs.

    Resistant Construction

    Unlike conventional units that use plastic, the DuroMax XP4850HX wraps a full metal construction and heavy-duty frames around the engine parts, protecting them from years of use and harsh conditions.

    To ease the burden of moving around rough terrain, the 4,850-watt unit is equipped with solid fill tires which provide greater grip on the ground and will never run flat. On top of that, it also features a foldable handle making the 129lbs unit a breeze to pull around just like all DuroMax portable generators.

    Fully Featured Power Panel

    The DuroMax XP4850HX features multiple outlets for maximum compatibility on the go, making it perfect for work sites and camp sites.

    For further safety, the fully featured power panel includes a battery switch and circuit breaker capable of shutting down the engine in case of overload.

    Benefits of Using Propane

    Even though you lose about 5% of power when using propane over gasoline, it can be game-changing depending on your living conditions. To name a few benefits:

  • Perfect for Winter: Liquid propane immediately runs through the fuel lines and does not need to be warmed up, unlike gasoline.
  • Widespread Resource: Propane is a cheaper alternative and can be found in gas stations and home centers during a power outage, whereas gasoline requires power to be poured from one container to another.
  • No Spills: Avoid the inevitable spilling when trying to pour gasoline into the engine by using a propane hose connecting directly to the propane inlet.
  • No Residue: Save the time and energy of cleaning the engine parts when using propane since it burns clean and leaves no waste whatsoever.
  • Reduced Carbon Emissions: Carbon monoxide along with other toxic gases can negatively impact your health. Propane reduces emissions by half to prevent any damage, making it perfect for outdoor scenarios.
  • Superior Shelf Time: Propane does not require any expensive additives to keep it from going bad and can be stored for decades, unlike gasoline which only lasts for a few months.
