Zoom on the DuroMax XP4400EH

In a nutshell, the DuroMax XP4400EH is a compact portable generator mostly geared towards:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Amateur DIY lovers
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • 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

With its dual-fuel technology, the powerful and versatile DuroMax XP4400EH provides an output of 120/240V. While gasoline-powered, it gives a running wattage of 3500W along with a peak wattage of 4400W. While propane-powered, it provides 3325 rated watts and 4180 starting watts.

The generator is rated for a noise of 69 dBA (less noisy than an office). Its starting mechanisms include a simple traditional pull-start mechanism and a simple and elegant electric starter (battery included).

The running time of the XP4400EH, with its 4 gallons fuel capacity, can reach around 11.5 hours at 50% load on a full tank of gasoline (fuel consumption around 0.35 GPH). With propane, it can reach around 10 hours (on a 20 lbs tank - propane consumption around 0.47 GPH).

Since the XP4400EH has a somewhat high THD (<12%), it is advisable to not use it for the powering of sensitive electronic devices.

Outlets

The control panel features the following 3 AC outlets:

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

Furthermore, it has 1 DC outlet: there's a 12V 8A output with which you may charge your batteries with ease.

Due to the featured twist-lock L14-30R receptacle, the XP4400EH is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

The design of the DuroMax XP4400EH is a typical, open frame, with the dimensions of L24 x W17 x H17 in, offering support and stability and enabling the possibility of raising it above ground level. The generator is designed for ideal use outdoors and in rough environments.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 125 lbs. However, its challenging mobility is solved by its wheel kit (⌀8") and its folding handle, which will ease its displacement, once it is on the floor.

Features

The XP4400EH's control panel

The XP4400EH and its control panel include a convenient voltmeter, which provides an easy way to monitor power output anytime. This feature comes handy when monitoring its status and activity.

In addition to this info, a light indicator allows you to instantly see if its oil levels are insufficient.

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off and an overload protection (circuit breaker).

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the DuroMax XP4400EH also comes with some accessories: propane hose, funnel and tool kit are included. An official storage cover is also available, as a separate purchase.

Emissions

The DuroMax XP4400EH is EPA-approved and CARB-compliant. Thus, selling and purchasing this generator is allowed in each of the 50 states, including California.

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

Product Video

The DuroMax XP4400EH versus other generators

The following charts are provided to give you an idea of how some of the key specs of the DuroMax XP4400EH compare to generators of similar power (between 3000 and 4000 W).

  • At a dry weight of 125 pounds, the DuroMax XP4400EH is one of the heavier devices which can produce between 3000 and 4000 running watts. In terms of weight, one of the champions in their power range is the WEN GN400i, standing at just 66.1 lbs.
  • As this generator can emit noise as low as 69 dBA, it finds itself in the average expected noise for this kind of power. 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.
  • The XP4400EH, falls within the average autonomy range compared to generators of a roughly same power, with a run time of around 11.5 hours at a 50% load and a full tank. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Honda EB4000X, 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 0.35 GPH (gallon per hour) at a 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4200. With a fuel consumption of as little as 0.17 GPH, it is one of the most efficient generators currently on the market.

Price comparison

As you can see from this interactive chart, when compared to other 3000-4000W generators, the DuroMax XP4400EH is on the average side of the price range.

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