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 wishing to enhance their freedom and nomad lifestyle
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • DIYers who wish to improve their efficiency with tools
  • 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

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 core is the 208 cc (7 hp) DuroMax OHV 4-stroke engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 3500W and a peak wattage of 4400W.

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 convenient and easy-to-use electric starter (battery included).

The fuel capacity of 4 gallons allows the XP4400E to operate for around 11.5 hours at 50% load with a full tank (fuel consumption around 0.35 GPH).

Since the XP4400E 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 upcoming 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 XP4400E is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

With its dimensions of L25 x W24 x H21 in, the conventional, open frame design of the DuroMax XP4400E offers stability and allows the generator 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). 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 XP4400E's control panel

To help you monitor the XP4400E's status and activity, its control panel is equipped with a handy voltmeter that allows you to easily monitor power output anytime.

In addition to this info, when its oil levels are insufficient, you will be informed by the featured light indicator.

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

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).

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the DuroMax XP4400E also comes with several accessories, including: battery charging cables, funnel and tool kit. 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 and thus, may be used 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).

  • Considering its dry weight of 122 pounds, the DuroMax XP4400E is one of the heavier generators producing between 3000 and 4000 running watts. If weight matters to you, one of the champions in this power range is the WEN GN400i with only 66.1 pounds.
  • Since the generator's noise is rated at 69 dBA, it has the roughly average expected noise for a device of similar power. If noise emissions are important to you, one of the least noisy generators of this power range is the Cat INV4000E with only 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 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 Predator 4375, with around 16 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 average fuel consumption among comparably powerful devices, as it reaches 0.35 GPH (gallon per hour) at a 50% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.17 GPH, the Westinghouse iGen4200 is a device you should look out for.

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.
