Description

The DEWALT DXGN14000 is designed with the professional contractor or rental operator in mind. This unit is powered by a 688cc Honda GX630 electric start OHV engine with auto shut off for low oil. The premium alternator provides low harmonic distortion. The large 10 Gal. tank with fuel gauge runs up to 8 hours at 50% load. Wheel kit and battery are included.

Zoom on the Dewalt DXGN14000

In summary, the Dewalt DXGN14000 is a powerful portable generator especially useful for 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 Dewalt DXGN14000's core is the 688 cc (20.2 hp) Honda GX630 OHV V-Twin engine, which runs on gasoline. With an output of 120/240V, it provides a running wattage of 11700W and a peak wattage of 14000W.

The generator is rated for a noise of 83 dBA (just slightly more noisy than garbage disposal). Its starting mechanism is based on a simple and elegant electric starter (battery included).

The DXGN14000 can operate for around 8 hours at 50% load with a full tank (fuel consumption around 1.25 GPH), due to its fuel capacity of 10 gallons.

As the DXGN14000 has a relatively high THD (<6%), it is not recommended to use it to power sensitive electronic devices.

Outlets

The control panel features the upcoming 6 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120/240V 30A (L14-30R) receptacle
120/240V 50A (14-50R) receptacle

Because the DXGN14000 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

With its dimensions of L31.6 x W33.3 x H36.4 in, the conventional, open frame design of the Dewalt DXGN14000 offers stability and allows the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

As the generator's weight is 344 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Nevertheless, it can still be moved quite conveniently with the help of its wheel kit (⌀13") and its folding handle, once it is placed on the ground.

Further safety during transport, loading and unloading of the device is provided by a lift hook, which is placed on the top of the generator's frame.

Features

The DXGN14000's control panel

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

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.

As for its accessories, apart from the previously mentioned features, the Dewalt DXGN14000 also comes with the basic documentation and an owner's manual (opens in a new tab), allowing you to start it right away.

Emissions

The Dewalt DXGN14000 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 Dewalt DXGN14000 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Dewalt DXGN14000 compare to generators of similar power (between 10000 and 14000 W).

  • At a dry weight of 344 pounds, the Dewalt DXGN14000 is one of the heavier devices which can produce between 10000 and 14000 running watts. If you are concerned by weight, one of the champions in the above-mentioned power range is the A-iPower SUA13000EFI, with a dry weight of just 218 pounds.
  • When compared to devices able to produce a similar running wattage, this generator and its lowest emitted noise of 83 dBA is on the noisier side. 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 A-iPower SUA13000EFI, whose lowest noise levels reach just 69 dBA.
  • As for its autonomy, the DXGN14000, with an autonomy of around 8 hours at a 50% load, is placed on the low end among the generators of its kind. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Powerhorse 13000ES, boasting with around 15 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. This generator is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 1.25 GPH at a 50% load. If you wish to acquire one of the most gasoline efficient products of this power range, the A-iPower SUA13000EFI, with a fuel consumption of 0.78 GPH could be in your good books.

Price comparison

As you can see from this interactive chart, when compared to other 10000-14000W generators, the Dewalt DXGN14000 is on the expensive side of the price range.

While certainly not the cheapest of its kind, purchasing it would most likely also mean enjoying the reliability of a high-end product.

I was under the impression that the <6% is good and acceptable to power sensitive electronics. (Asked November 07, 2020)

We consider that THD should remain <5% in order to safely power sensitive electronics.
