Zoom on the DuroMax XP4400EH

In summary, the DuroMax XP4400EH is a portable generator especially useful for:

  • 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 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 XP4400EH in use

The DuroMax XP4400EH

The dual-fuel technology of the DuroMax XP4400EH allows for an output of 120/240V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 3,500W and a starting wattage of 4,400W. If propane-powered, it gives 3,325 rated watts and 4,180 starting watts.

The generator features a conventional pull-start mechanism and also a convenient and easy-to-use electric starter (battery included). It is rated for a noise of 69 dBA (less noisy than background music).

As for its running time, the XP4400EH, along with its 4 gallons fuel capacity, can run for around 11.5 hours at 50% load with a full tank filled with gasoline (fuel consumption around 0.35 GPH). If propane is used, it can operate for around 10 hours (on a 20 lbs tank - propane consumption around 0.47 GPH).

The powering of sensitive electronic devices with the XP4400EH is not recommended due to its relatively high THD (<12%).

Outlets

The control panel features the upcoming 3 AC outlets:

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

Additionally, it features 1 DC outlet: there's a 12V 8A output with which charging your batteries is made easy.

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 dimensions of the DuroMax XP4400EH, which are L25 x W24 x H21 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

As the generator's weight is 122 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Still, once it is on the ground, its wheel kit (⌀8") and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

Features

The XP4400EH's control panel

The XP4400EH's status and activity may be monitored conveniently via the control panel, as it features a convenient voltmeter, which provides an easy way to monitor power output anytime.

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

The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the DuroMax XP4400EH, the following accessories are also included: tool kit, funnel and propane hose. 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 thus, may be used in forested areas.

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 dual fuel generators of similar power (between 3000 and 4000 W).

  • At a dry weight of 122 pounds, the DuroMax XP4400EH is one of the heavier dual fuel devices which can produce between 3000 and 4000 running watts. In terms of weight, one of the champions in their power range is the Genmax GM3500iAED, standing at just 56.2 lbs.
  • If compared to generators capable of producing a similar running wattage, this generator with a lowest emitted noise of 69 dBA can be considered somewhat noisy. For those who are looking for a less noisy device, we suggest the Westinghouse iGen4500DF. With just 52 dBA, it is one of the most quiet devices in this power range.
  • The XP4400EH, offering a run time of around 11.5 hours with a full tank at a 50% load, falls within the average autonomy range when compared to its peers. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Westinghouse iGen4500DF, which is able to run for around 15 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. This generator has an estimated fuel consumption of roughly 0.35 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen4500DF, which has a fuel consumption of only 0.23 GPH and thus, is one of the most efficient devices in our database.

Price comparison

As you can see from this interactive chart, when compared to other 3000-4000W dual fuel 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.
