    A Lightweight and Efficient Portable Generator

    Although the DuroMax XP5500HX only features a 210cc engine, it is nothing short of remarkable. The unit can deliver considerable levels of power with no hiccups thanks to 5,500-watt peak performance, allowing you to power your appliances and even make yourself and hot beverage while you’re at it.

    The ample 210cc headroom allows the cylinders to efficiently digest air, which translates into better performance and less strain on the engine. In addition, while the splash-type cooling oil system provides optimal working temperatures, the engine can run at 3600RPM to make sure all your problems are solved.

    To top it off, 100% copper windings allow for improved heat dissipation. This leads to increased performance since aluminum is an inferior heat conductor.

    The DuroMax XP5500HX Uses Dual Fuel Technology

    The XP5500HX dual fuel generator combines efficiency and convenience by running on both gasoline and propane thanks to Dual Fuel Technology. Pick whichever fuel is on the shelf and immediately get to work.

    For added convenience, the portable generator uses an idle control feature that automatically lowers engine speeds to prolong runtime, along with an automatic voltage regulator that prevents voltage spikes and raises the engine’s tolerance for power surges.

    CO Alert

    The DuroMax XP5500HX brings safety measures to another level with its CO Alert feature. For an even safer environment, the portable generator automatically shuts down if carbon monoxide levels emitted by the engine are high.

    Carbon monoxide can be a deadly hazard in the worst-case scenario. The DuroMax generator protects you, your family, and your friends so you can focus on your mission or simply have a good time with no worries.

    Outdoor Use

    The DuroMax XP5500HX complies with strict eco-friendly guidelines provided by the Environmental Protection Agency (EPA) and California Air Resources Board (CARB). This means the engine regulates pollution and emits fewer toxic fumes, making it the ideal solution for camping trips and family gatherings.

    Industrial DuroMax Durability with the  XP5500HX

    To make sure your investment is protected, full metal construction and frames surround the engine and power panel to adapt to severe weather conditions and years of wear-and-tear.

    Besides the robust build, solid fill tires and a foldable handle provide a stronger contact with the ground, making this unit a breeze to push around just like all DuroMax models.

    Fully Loaded Power Panel

    The 5,500-watt dual fuel generator has it all: an electric start button, a circuit breaker and battery switch in case of overloads, an idle control switch to save fuel, and a wide range of outlets, perfect for workers on a job site.

    Next to the fully featured power panel lies a front fuel input switch where you can choose between gasoline and propane.

    Benefits of Using Propane

    Even though gasoline can yield about 5% more power, using propane can be beneficial depending on living conditions. Here are some benefits of using propane:

    • Quick Start: Unlike gasoline, propane doesn’t need to be warm to make its way through the fuel lines, making it ideal for cold temperatures.
    • Cheaper and Effective: Propane is a much more widespread resource, and is thus cheaper. It also burns for longer.
      • Easy Maintenance: You will inevitably spill gasoline on the ground while trying to pour it from one container to another. Propane can be connected through a propane hose with no spills whatsoever. 
      • Clean Fuel Source: Propane is a clean-burning fuel. This avoids you having to clean the residue off the fuel lines, unlike gasoline which can leave dirty spots all around the engine parts.
      • Environment-Friendly: By emitting only half as much carbon monoxide, propane qualifies as the healthier option and reduces the risks of dizziness and health hazards if you’re in close proximity to the unit for extended periods of time.
      • Longer Shelf Time: Gasoline requires expensive stabilizers in order to keep it from going bad and can only last for a few months. Propane doesn’t and can be stored for up to 30 years without any additives.
