Zoom on the DuroMax XP4400EH

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

  • RV travellers looking for even more independence
  • 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 in need of safely powering high-intensity work or lighting equipment

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from and any relevant emission compliance details.

Power & Run Time

Thanks to its dual-fuel technology, the DuroMax XP4400EH delivers 120/240V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 3500W and a peak wattage of 4400W. When propane-powered, it has 3325 rated watts and 4180 peak watts.

At a noise rating of 69 dBA (less noisy than background music), this generator can be started via a simple traditional pull-start mechanism, or a convenient and easy-to-use electric starter (battery included).

With a fuel capacity of 4 gallons, the XP4400EH can operate for around 11.5 hours at 50% load using gasoline (fuel consumption around 0.35 GPH), or for around 10 hours (on a 20 lbs tank - propane consumption around 0.47 GPH) using propane.

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

Here are a few examples of what this generator could allow you to simultaneously power:Note: The above mentioned examples presume a maximum load of 75% and use wattage estimates. In addition, the items might not be able to start simultaneously. With our wattage calculator, you can predict if the product can fulfill your requirements.

Outlets

The control panel features the following 3 AC outlets:

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

In addition, it provides 1 DC outlet: there's a 12V 8A output allowing you to easily charge your batteries.

Since the XP4400EH bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.

Portability

The dimensions of the DuroMax XP4400EH, which are L24 x W17 x H17 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. This type of design is ideal for tough environments and heavy outdoor use.

As the generator's weight is 125 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, its challenging mobility is solved by a wheel kit (⌀8") and a folding handle, which will ease its displacement, once it is on the floor.

The XP4400EH's control panel

The XP4400EH's status and activity may be monitored conveniently via the control panel, as it features a handy voltmeter that allows you to easily monitor power output anytime.

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

The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

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.

With the basic documentation and a user manual, letting you start the generator quickly, the DuroMax XP4400EH also comes with several accessories, including: propane hose, funnel and tool kit.

Emissions

The DuroMax XP4400EH 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 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 generators of similar power (between 3000 and 4000 W).

  • As its weight is 125 pounds, the DuroMax XP4400EH falls in the expected weight range of the devices in the 3000-4000 rated wattage category. Regarding dry weight, one of the champions in the same power range is the Generac GP3500iO, with a dry weight of only 74.3 lbs.
  • When compared to devices able to produce a similar running wattage, this generator and its lowest emitted noise of 69 dBA is on the noisier side. If you are concerned with noise, check out the Westinghouse iGen4500, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
  • As the XP4400EH offers 11.5 hours run time on a full tank at a 50% load, it falls within the average autonomy range among the generators of a similar power. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Honda EB4000, with 16 hours .
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. As this generator uses an estimated 0.35 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. 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 dynamic 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.
