Compact and Balanced

Handle multiple jobs with ease and confidence using 4,500 watts of running power. Capable of powering high-amperage power tools as well as small and large appliances, the XP5500DX is dependable and reliable for professionals and homeowners alike.

To prevent the unit from overheating and damaging itself in the long run, DuroMax generators are equipped with 100% copper windings. Superior to the cheaper aluminum, copper offers improved heat dissipation that allows the unit to perform smoothly and consistently.

Dual Fuel Technology

Emergencies can happen at any time which leaves no room for blind guesses. Conveniently, the DuroMax XP5500DX uses innovative Dual Fuel Generator Technology to run on both gasoline and propane. This means you can use whichever fuel is more accessible while taking advantage of the game-changing benefits that using propane can yield, such as quick start-up.

Additionally, using propane allows you to cut toxic emissions by a staggering 50% to promote a healthier and safer environment for you and your loved ones.

Restless Performance

Shifting your focus from the oil gauge to what's truly important in the moment, the XP5500DX lasts for up to 9 hours at 50% load, so you can keep going during blackouts and remain productive throughout your workdays.

Whenever the unit is inactive, Idle Control decreases engine speeds to save fuel and money, and extend runtime.

CO Alert

Relying on a portable generator to keep your home running can overlook the health hazards of carbon monoxide poisoning, caused by the colorless and odorless gas.

CO Alert Technology is an automatic shut-off system that triggers whenever it detects unusual levels of carbon monoxide in order to keep you safe.

Certified Eco-friendly Rating

While many generators produce harmful emissions that can have increasingly harmful effects without you even realizing it, DuroMax generators meet strict eco-conscious guidelines from the Environmental Protection Agency (EPA) and the California Air Resources Board (CARB).

Since they are both EPA and CARB-approved, the units' toxic emissions fall far below standards, ensuring you're safe and healthy before helping you tackle your tasks.

Heavy-duty Build

Combining full metal construction, steel frames, grippy solid-fill tires, and foldable handles, the DuroMax XP5500DX remains stable, steady, and supported.

While the rugged body counteracts harsh and unpredictable weather, solid-fill tires provide a solid grip on rough terrain while the handles allow for a comfortable way of moving the unit around, and even allow for more space when folded up.

Fully Loaded Power Panel

The XP5500DX dual fuel generator is where performance meets safety and convenience. Thanks to multiple outlets, the 5,500-watt portable generator ensures maximum compatibility for on-the-go operation.

The fully featured power panel includes an L14-30R receptacle, making the unit transfer switch-ready. This means that you can safely and easily plug it into your home breaker box to immediately power your lights and appliances, turning night into day in a matter of seconds.

An oil gauge, low oil indicator, and low oil shutoff help you keep track of oil levels and give you a little heads-up before proceeding to shut the engine down entirely to prevent contaminated oil from damaging the unit.

Although electrical overloads can be a potential fire hazard, circuit breakers keep you safe by cutting the power short before any devastating damage is done.

Benefits of Using Propane

Made possible by innovative Dual Fuel Technology, you can now make decisions that suit your living conditions and availability in terms of fuel sources.

Compared to its fossil-fuel counterpart, gasoline, propane is typically about 5% less powerful, but the benefits can be game-changing depending on your living conditions:

  • Quick Start-Up: Propane is the perfect solution for power generation in cold weather conditions, and remains ready to go at the press of a button using the electric start, or the recoil mechanism if the battery is drained.
  • Affordable and Accessible: With no need for electricity, you can easily get your hands on propane during power outages from local shops and home centers, whereas gasoline requires power in order to be pumped from the gas station into your container, whilst also being more expensive.
  • No Spills: An otherwise inevitable and difficult-to-clean mess can be avoided by using a propane hose that directly plugs into the unit.
  • Low Maintenance: Propane burns clean due to its nature as a green fuel and leaves little to no residue around the fuel lines and engine parts, making it a hassle-free option.
  • 50% Lower Toxins: As a green fuel, propane results in 50% lower toxic emissions after combustion. Dual Fuel Technology allows you to remain productive with no compromise to your safety.

Extended Shelf Time: Gasoline only lasts a few months while propane can last 30 years without any stabilizers.
