Zoom on the DuroMax XP4500DX

In summary, the DuroMax XP4500DX is a portable generator especially useful for:

  • RV travellers looking for even more independence
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Handcrafting enthusiasts who wish to work on-the-go
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Professionals who want to be able to deliver results, even during a power failure

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The DuroMax XP4500DX in use

The DuroMax XP4500DX

Thanks to its dual-fuel technology, the DuroMax XP4500DX delivers 120/240V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 3500W and a peak wattage of 4500W. When propane-powered, it has 3325 rated watts and 4275 peak watts.

The generator features a simple traditional pull-start mechanism and also a simple and elegant electric starter (battery included). It is rated for a noise of 69 dBA (less noisy than a normal conversation).

Regarding its running time, the XP4500DX, with a 4 gallons fuel capacity can operate for around 10.4 hours at 50% load with a full tank of gasoline (fuel consumption around 0.38 GPH). When using propane, it can run for around 8.9 hours (on a 20 lbs tank - propane consumption around 0.53 GPH).

The powering of sensitive electronic devices with the XP4500DX is not recommended due to its relatively high THD (<12%).

Outlets

The control panel includes the following 3 AC outlets:

Duplex 120V 20A (5-20R) GFCI
120/240V 30A (L14-30R) receptacle

As the XP4500DX holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home during a power outage.

Portability

The dimensions of the DuroMax XP4500DX, which are L25 x W23 x H22 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 126 lbs make it incredibly difficult to manually lift and transport. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit and its folding handle, once it is placed on the ground.

Features

The XP4500DX's control panel

To help you monitor the XP4500DX's status and activity, its control panel is equipped with a convenient meter showing you voltage, frequency and lifetime hours.

In addition to this info, the device’s light indicator will display if the oil level is too low.

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.

The XP4500DX also benefits from DuroMax’s CO Alert carbon monoxide shutdown. If CO levels become unsafe or rapidly increase, the generator will automatically shut down, an indicator will light red, and the engine will not restart for 5 minutes. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the DuroMax XP4500DX's package also includes these accessories: propane hose, tool kit and funnel.

Emissions

The DuroMax XP4500DX is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor and therefore, can be used in forested areas.

Product Video

The DuroMax XP4500DX versus other generators

The following charts are provided to give you an idea of how some of the key specs of the DuroMax XP4500DX compare to generators of similar power (between 3000 and 4000 W).

  • Considering its dry weight of 126 pounds, the DuroMax XP4500DX is one of the heavier generators producing between 3000 and 4000 running watts. If weight is your top priority, one of the champions in this power category is the Genmax GM3300i, weighing just 47.4 pounds.
  • As this generator has its lowest possible noise of 69 dBA, it should be considered noisier compared to its peers of a comparable running wattage. For those who are looking for a less noisy device, we suggest the Cat INV4000E. With just 51 dBA, it is one of the most quiet devices in this power range.
  • Offering around 10.4 hours of running time on a full tank at 50% load, the XP4500DX is within the average autonomy range of similarly powerful generators. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Predator 4375, reaching around 16 hours.
  • Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. This generator has an average fuel consumption among comparably powerful devices, as it reaches 0.38 GPH (gallon per hour) at a 50% load. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4200, with a fuel consumption of 0.17 GPH could be in your good books.

Price comparison

As you can see from this interactive chart, when compared to other 3000-4000W generators, the DuroMax XP4500DX is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
