    Reliable Power Source

    Using a state-of-the-art 457cc DuroStar engine combined with efficient thermal control, the 12,000-watt portable generator reaches 9,500 watts of running power. This way, this unit presents itself as the perfect option to power heavy-duty power tools if you’re on a mission or small and large appliances during a power outage or camping trip.

    Unlike conventional builds that use aluminum, DuroStar generators use 100% copper windings, a superior heat conductor that allows for improved heat dissipation and thus less strain on the unit and a longer lifetime.

    On top of that, MX2 Power Boost Technology allows the engine to double its voltage up to 240V for even greater power.

    Dual Fuel Technology by DuroStar

    Through clever design, the DuroStar DS12000EH uses innovative Dual Fuel Technology to run on both propane and gasoline. Moreover, you can easily choose which source to use from the side-mounted fuel input switch and being producing power in seconds.

    Additionally, the idle control feature automatically lowers engine speeds when the unit is not being used to save on fuel and cost and extend runtime. This is one of the most popular DuroStar dual fuel models.

    Eco-conscious Use

    Following strict guidelines regarding toxic emissions, the 12,000-watt portable generator is both EPA and CARB-approved. This means that it features controlled unhealthy emissions to provide you with a worry-free and healthy experience even when in close proximity to the unit, making it ideal for a family gathering or festival.

    By enforcing healthy environmental practices, the Environmental Protection Agency and California Air Resources Board ensure that units such as the DuroStar DS12000EH minimize health issues and provide an eco-friendly option.

    Built Tough

    The 12,000-watt portable generator is reinforced by full metal construction to ensure years of use even when exposed to harsh weather conditions.

    For further convenience, solid-fill tires offer an easier time going through rough ground by providing a stronger grip and never running flat.

    Fully Loaded DuroStar Power Panel

    Designed for maximum compatibility, the DuroStar DS120000EH provides multiple outlets for different uses, including an L14-30R receptacle that allows you to plug the unit into your home breaker box to power your lights and appliances.

    To promote safety, a circuit breaker automatically shuts the engine down in case of overload, while the low oil shutoff automatically turns it off when oil levels are insufficient.

    Benefits of Using Propane

    Using propane offers a multitude of advantages depending on your living conditions. Although gasoline yields about 5% more power, propane can be a cheaper, healthier, and more efficient option:

  • Immediate Start: Unlike gasoline, propane immediately starts powering the engine and does not need to be warmed up which is perfect for cold seasons and locations.
  • Cheaper: Propane can be found in shops, home centers, and gas stations at a lower price.
  • No Spilling: Avoid any spilling by using a propane hose since gasoline will inevitably be spilled on the ground when being poured from one container to another.
  • No Cleaning: Unlike gasoline, propane leaves no unwanted residue in the fuel lines and engine parts. This means you don’t have to clean up every time you use the unit.
  • Reduced Unhealthy Gases: By burning clean, propane emits 50% fewer toxic fumes, making it ideal for users who will be in close proximity for extended periods of time.
  • Stored for Longer: While gasoline can only last a few months without the use of expensive stabilizers, propane can sit on your shelf for up to 30 years with no need for additives.
