    Off-the-grid DuroMax Capabilities

    Using the latest and greatest that DuroMax generator engines have to offer, the XP4500iH dual fuel generator clocks in at a fantastic 4,500 watts of maximum power, allowing all your appliances to run properly in addition to charging external batteries.

    Combined with copper windings providing superior heat conduction compared to aluminum, the unit uses an alternator coupled with a microprocessor to generate power in a more efficient method, allowing the DuroMax XP4500iH to remain light, quiet, and productive.

    Dual Fuel Technology

    Using innovative Dual Fuel Technology, this 4,500-watt DuroMax inverter generator can function using both gasoline and propane and reach up to 19 hours of runtime, providing efficiency, reliability, and convenience.

    Also thanks to idle control, the engine saves even more energy by automatically lowering the RPM when it detects it’s not being used. Working in harmony with the idle control, an automatic voltage regulator stabilizes the engine in case of voltage spikes, protecting it from wear-and-tear for years to come.

    CO Alert

    To protect its user from the dangers of accumulated carbon monoxide, the DuroMax XP4500iH features a smart technology that allows it to automatically switch the engine off when it detects that emitted carbon monoxide levels are high.

    The DuroMax XP4500iH guarantees a healthy and worry-free experience to host your peace of mind.


    The DuroMax XP4500iH follows health standards provided by the Environmental Protection Agency and California Air Resources Board, meaning it is both EPA and CARB-approved and therefore environment-friendly.

    By complying with those guidelines, the 4,500-watt inverter generator show controlled emissions and reduces toxic fumes by 50%, making it the ideal solution for job sites and camping sites where users will be in close proximity to the unit.

    Robust Build

    Protecting the sleek attire of the DuroMax XP4500iH, full metal construction and heavy-grade frames are resistant to harsh weather conditions and years of wear-and-tear.

    To facilitate going through rough terrain, solid-fill tires can help you navigate anywhere, never running flat and providing you with power anywhere you go.

    Fully Loaded Power Panel

    Plug your appliances, charge your batteries, and power your tools in seconds thanks to multiple outlets and maximum compatibility. The 4,500-watt inverter generator is perfect for construction sites where different tools are being used.

    To push convenience even further, the fully featured power panel includes a circuit breaker next to the battery switch, both allowing you to turn the unit off in case of an emergency such as overload or a power surge.

    Benefits of Using Propane

    The DuroMax dual fuel range uses gas and propane. Although only capable of delivering 95% of the power that gasoline provides, using liquid propane as a fuel source can be extremely convenient. Some benefits include:

  • Immediate Start: Because it doesn’t need to be warmed up, propane immediately powers the engine, which is exceptionally helpful in cold locations and weather.
  • Economical: Liquid propane is a widespread resource, thus making it the cheaper option compared to gasoline, and when paired with an inverter generator such as the DuroMax XP4500iH, the runtime is even longer.
  • Avoid Spilling: Thanks to a propane hose that connects via an inlet, propane will flow directly into the engine with no spills whatsoever.
  • Clean-burning Fuel: Gasoline leaves residue all over the fuel lines, exhaust, and other engine parts. Propane doesn't, meaning you don’t have to clean them even after extended use.
  • Suited for Outdoor Use: Using propane on the DuroMax XP4500iH dual fuel generator results in half the carbon monoxide emissions, making it the healthiest option.
  • No Additives Needed: While gasoline requires expensive stabilizers to preserve itself, propane can be stored for as long as 30 years with no additives.
