Description

The XP4400E is a tried and true piece of equipment. It is well worth its weight in gold; as soon as the box is opened you will be amazed at the amount of thought and science that was put into designing this unit. (source: DuroMax (opens in a new tab))

Zoom on the DuroMax XP4400E

In summary, the DuroMax XP4400E is a portable generator especially useful for:

  • RV travellers who wish to upgrade their experience to another level
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Amateur DIY lovers
  • Homeowners in need of an emergency backup power for their essentials
  • Professionals who want to be able to deliver results, even during a power failure

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.

Power & Run Time

The DuroMax XP4400E's engine, 208 cc (7 hp) DuroMax OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 3500W and reaches a peak wattage of 4400W.

With a noise rating of 69 dBA (less noisy than an office), the generator features a conventional pull-start mechanism, but also a convenient and easy-to-use electric starter (battery included).

With a full tank, the XP4400E can operate for around 11.5 hours at 50% load (fuel consumption around 0.35 GPH), thanks to its fuel capacity of 4 gallons.

The quite high THD (<12%) of the XP4400E makes it unsuitable for powering sensitive electronic devices.

Outlets

The control panel provides the upcoming 3 AC outlets:

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

It also sports 1 DC outlet: there's a 12V 8A output with which charging your batteries is made easy.

As it features a twist-lock L14-30R receptacle, the XP4400E is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.

Portability

The DuroMax XP4400E has a conventional, open frame design, of the following dimensions: L25 x W24 x H21 in, which offers support and allows it to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

Since the generator weighs 122 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). However, this lack of maneuverability is compensated by its wheel kit (⌀8") and its folding handle, with which you can conveniently shift it, once it's on the ground.

Features

The XP4400E's control panel

The XP4400E 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 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 overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the DuroMax XP4400E also comes with some accessories: battery charging cables, funnel and tool kit are included. An official storage cover is also available, as a separate purchase.

Emissions

The DuroMax XP4400E is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.

Moreover, it features a spark arrestor, which makes it suitable for use in forested areas.

Product Video

The DuroMax XP4400E versus other generators

The following charts are provided to give you an idea of how some of the key specs of the DuroMax XP4400E compare to generators of similar power (between 3000 and 4000 W).

  • Since the generator weighs in at a dry weight of 122 lbs, the DuroMax XP4400E belongs in the expected weight range for devices which can produce between 3000 and 4000 rated watts. In terms of weight, one of the champions in their power range is the WEN GN400i, standing at just 66.1 lbs.
  • This generator has a somewhat average expected noise for its power range, rated at 69 dBA. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Cat INV4000E, whose lowest noise levels reach just 51 dBA.
  • Given that the XP4400E reaches an autonomy of around 11.5 hours with a full tank and at 50% load, it is placed within the average autonomy range of similarly powerful generators. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Predator 4375, boasting with around 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. Standing at an estimated 0.35 GPH (gallon per hour) at a 50% load, this generator is somewhat average in this area compared to other devices, within the aforementioned wattage range. 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 XP4400E is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.
