Zoom on the Dewalt DXGN14000

In a few words, the Dewalt DXGN14000 is a powerful portable generator perfectly suited for professionals in need of safely powering high-intensity work or lighting equipment..

Over the following sections, you'll uncover its power characteristics, the selection of outlets it offers, its overall portability, and the supplementary features it includes.

Power & Run Time

The Dewalt DXGN14000 is powered by a 688 cc (20.2 hp) Honda GX630 OHV V-Twin engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 11,700W as well as a peak wattage of 14,000W.

With a noise rating of 83 dBA (just slightly more noisy than garbage disposal), the generator's ignition is facilitated by a simple and elegant electric starter (battery included).

The DXGN14000's fuel tank, boasting 10 gallons, allows it to operate for around 8 hours at 50% load with a full tank (with an estimated fuel consumption of 1.25 GPH).

The powering of sensitive electronic devices with the DXGN14000 is not recommended due to its relatively high THD (<6%).


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.


With dimensions of L31.6 x W33.3 x H36.4 in, the standard open frame design of the Dewalt DXGN14000 provides stability and easy maintenance access to components, as well as good air circulation. 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 344 pounds. Nevertheless, the restricted maneuverability is counteracted by its wheel kit (⌀13") and its folding handle, enabling easy shifting once the generator is set in place.

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.

With its built-in fuel gauge, the generator provides quick and convenient gas level checks.

As far as security is concerned, the generator comes with an overload protection (circuit breaker) and an automatic low oil shut-off, providing peace of mind during use.

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.

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).

  • Weighing 344 lbs, the Dewalt DXGN14000 is one of the heavier generators within the 10000-14000 rated wattage bracket. If weight is an important consideration for you, the A-iPower SUA13000EFI stands out as one of the top contenders in this power category, with a dry weight of 218 pounds.
  • When compared to other units producing a similar running wattage, this generator and its lowest emitted noise of 83 dBA stand out for being on the louder side. If you'd like a less noisy alternative, the DuroMax XP16000iH is a strong contender. It boasts a noise rating of 67 dBA, placing it among the quietest generators in its power category.
  • Concerning its runtime, the DXGN14000 provides around 8 hours at a 50% load, indicating that it falls on the lower side compared to other generators of its power range. 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 Powerhorse 13000ES, with around 15 hours.
  • Run time is crucial, but it heavily relies on the fuel tank's capacity. Thus, considering fuel efficiency alongside is essential. 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 get a unit of similar power, but with one of the best fuel efficiency, you could consider the A-iPower SUA13000EFI, which has an impressively low fuel consumption of 0.78 GPH.

The bottom line

  • GFCI Outlets
  • Honda engine
  • Electric start
  • No data center
  • No recoil back-up
  • No remote start
  • On the heavy side (344 lbs)
  • On the noisy side (83 dBA)
  • Relatively low run time
  • Low fuel efficiency

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.
