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 compact portable generator especially useful for:

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in outdoor fairs, festivals or events
  • 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

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

The DuroMax XP4400E is powered by a 208 cc (7 hp) DuroMax OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 3500W as well as a peak wattage of 4400W.

The generator is rated for a noise of 69 dBA (less noisy than a normal conversation). Its starting mechanisms include a conventional pull-start mechanism and a convenient and easy-to-use electric starter (battery included).

With a fuel capacity of 4 gallons, the XP4400E may run for around 11.5 hours at 50% load with a full tank (fuel consumption around 0.35 GPH).

The powering of sensitive electronic devices with the XP4400E is not recommended due to its relatively high THD (<12%).

Outlets

The control panel features the following 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 you may charge your batteries with ease.

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 dimensions of the DuroMax XP4400E, 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. The generator is designed for ideal use outdoors and in rough environments.

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). Nevertheless, thanks to its wheel kit (⌀8") and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

Panel of the DuroMax XP4400E

The XP4400E's control panel

The control panel of the XP4400E includes a handy voltmeter that allows you to easily monitor power output anytime, helpful for the monitoring of its status and activity.

In addition to this info, a light indicator serves to show you when 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.

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.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the DuroMax XP4400E's package also includes these accessories: funnel, tool kit and battery charging cables. An official storage cover is also available, as a separate purchase.

Emissions

The DuroMax XP4400E 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, so it is adequate 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).

  • At a dry weight of 125 pounds, the DuroMax XP4400E 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.
  • Because this generator emits noise as low as 69 dBA, it can be considered to have a pretty average expected noise rating for a device of its 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.
  • The XP4400E, 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. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Honda EB4000X, as it provides 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. 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 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.
