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 a nutshell, the DuroMax XP4400E is a portable generator mostly geared towards:

  • RV travellers looking for even more independence
  • 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 ensure that a power failure will not prevent them from working

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 houses a 208 cc (7 hp) DuroMax OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 3,500W along with a peak wattage of 4,400W.

Enjoying a noise rating of 69 dBA (less noisy than an office), this generator can be started thanks to a simple traditional pull-start mechanism, but also to a simple and elegant 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).

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

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 allowing you to easily charge your batteries.

Because the XP4400E is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to 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. This type of design is ideal for tough environments and heavy outdoor use.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 122 pounds. 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 convenient voltmeter, which provides an easy way to 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.

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

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

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: tool kit, funnel 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. 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.

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 Pulsar PGD40iSCO with only 46 pounds.
  • As this generator has its lowest possible noise of 69 dBA, it should be considered noisier compared to its peers of a comparable running wattage. If noise emissions are one of your priorities, you may be interested in the Westinghouse iGen4500DF, one of the least noisy generators similarly powerful as this one, rated for 52 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. 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.
  • 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. This generator reaches an estimated fuel consumption of 0.35 GPH (gallon per hour) at a 50% load, making it average, for the previously mentioned wattage range. If fuel consumption is your top priority, we suggest to check out the Pulsar PGD40iSCO, which has a fuel consumption of only 0.22 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 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.

    This is a really nice unit right out of the box with lots of accessories. It starts and runs well. Being a 4400 starting and 3500 running, It ran most all of my need appliance with no issue. Just be careful not to overload with too many heavy appliances at once. Like make coffee and turn coffee of for the microwave or hairdryer..

    + PROS:
    • The Generator is very easy to move around ,also having an interlock on my panel makes it easy to turn on most all needed items. Ran TV and two fridge and all needed lights perfectly.
    - CONS:
    • The gas cap is a tight one and a little hard to remove when new. Also make sure to tighten the handle so that it does not try to fold when lifting.
