Reliable DuroMax Performance

The XP4500DX is the perfect generator for those who need to power multiple devices simultaneously. With 3,500 watts of running power, it can handle high-amperage power tools as well as small and large appliances with ease.

For extra power, the 4,500-watt portable generator houses the MX2 Power Boost feature that forces the unit to run at double the voltage, i.e. 240V.

The DuroMax generators are equipped with 100% copper windings to prevent the unit from overheating and damaging itself over time. Since copper is superior to aluminum, it provides improved heat dissipation, thus allowing the unit to perform smoothly and consistently.

Dual Fuel Technology

The XP4500DX uses cutting-edge Dual Fuel Technology so that it can run on both gasoline and propane. This way, you're never caught off guard without a backup plan. Not to mention, using propane has remarkable benefits like a speedy startup.

Propane doesn't only save you money, it's also much better for the environment. Compared to other fossil fuels, propane cuts toxic emissions by 50%. This creates a healthier and safer space for you and your family. See more DuroMax dual fuel models here.

Extensive Runtime

Keep your mind focused and your thoughts off the oil gauge with up to 10 hours of off-the-grid freedom. Capable of sustaining a 50% load for hours on end, the DuroMax XP4500DX ensures you remain productive and operational no matter where you decide to go.

With Idle Control, the unit automatically saves fuel and money by reducing engine speeds when it's inactive. This feature also extends runtime so you can get more use out of your equipment.

CO Alert

Overlooking the health hazards of carbon monoxide poisoning can occur when relying on a portable generator for extended periods of time or when operating in enclosed spaces.

Carbon monoxide is a colorless and odorless gas that automatically triggers CO Alert Technology to shut the engine down whenever it detects unusual levels in order to keep you safe.
