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 a nutshell, the Dewalt DXGN14000 is a powerful portable generator mostly geared towards professionals in need of safely powering high-intensity work or lighting equipment.

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.

With a noise rating of 83 dBA (just slightly more noisy than garbage disposal), the generator features a simple and elegant electric starter (battery included).

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

The quite high THD (<6%) of the DXGN14000 makes it unsuitable for powering sensitive electronic devices.

Outlets

The control panel includes the following 6 AC outlets:

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

As it features a twist-lock L14-30R receptacle, the DXGN14000 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 Dewalt DXGN14000 has a conventional, open frame design, of the following dimensions: L31.6 x W33.3 x H36.4 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 344 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). Nevertheless, thanks to its wheel kit (⌀13") and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

A lift hook, which is on the top of the frame, serves as an extra safety feature for the transport, unloading and loading of the device.

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.

Accessory-wise, along with the previously mentioned features, the Dewalt DXGN14000 is packaged with the standard documentation and an owner's manual (opens in a new tab), helping you start the device right away.

Emissions

The Dewalt DXGN14000 is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor, so it is adequate for use 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).

  • With its weight of 344 lbs, the Dewalt DXGN14000 is one of the heavier generators in the 10000-14000 rated wattage category. Regarding dry weight, one of the champions in the same power range is the A-iPower SUA13000EFI, with a dry weight of only 218 lbs.
  • Among the generators of a comparable running wattage, this generator with a lowest noise of 83 dBA can be judged as noisy. If noise emissions are one of your priorities, you may be interested in the A-iPower SUA13000EFI, one of the least noisy generators similarly powerful as this one, rated for 69 dBA.
  • As far as autonomy is concerned, providing around 8 hours of runtime with a full tank at a 50% load, the DXGN14000 falls into the low end in comparison with other devices of a comparable power output. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Powerhorse 13000ES, which is able to run for around 15 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. In fact, this generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 50% load is around 1.25 GPH. 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.

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.
