Zoom on the Dewalt DXGN14000

In a nutshell, the Dewalt DXGN14000 is a powerful portable generator mostly geared towards 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 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 11700W as well as a peak wattage of 14000W.

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

With a fuel capacity of 10 gallons, the DXGN14000 may run for around 8 hours at 50% load with a full tank (fuel consumption around 1.25 GPH).

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 following 6 AC outlets:

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

Due to the featured twist-lock L14-30R receptacle, the DXGN14000 is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

The Dewalt DXGN14000 has the following dimensions: L31.6 x W33.3 x H36.4 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The device has been designed for tough environments and demanding 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. However, this lack of maneuverability is compensated by its wheel kit (⌀13") and its folding handle, with which you can conveniently shift it, once it's on the ground.

The generator comes with an additional safety feature, a lift hook on the top of its frame, which is helpful during its transport, loading and unloading.

The DXGN14000's control panel

The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

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

Along with the aforementioned features, from an accessory standpoint, the Dewalt DXGN14000's box includes the typical documentation and an owner's manual (opens in a new tab), which will help you start your generator promptly.

Emissions

The Dewalt DXGN14000 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 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).

  • Considering its dry weight of 344 pounds, the Dewalt DXGN14000 is one of the heavier generators producing between 10000 and 14000 running watts. If weight is your top priority, one of the champions in this power category is the A-iPower SUA13000EFI, weighing just 218 pounds.
  • As this generator has its lowest possible noise of 83 dBA, it should be considered noisier compared to its peers of a comparable running wattage. 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.
  • The DXGN14000's autonomy is somewhat low end compared to devices of its power range, as it reaches only around 8 hours at 50% load on a full tank. 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.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. Compared to its peers, this generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 1.25 GPH at a 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the A-iPower SUA13000EFI. With a fuel consumption of as little as 0.78 GPH, it is one of the most efficient generators currently on the market.

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.
