Picture of the Dewalt DXGN4500

Description

The DEWALT DXGN4500 is designed with the professional contractor or rental operator in mind. This unit is powered by a 270cc Honda GX270 manual start OHV engine with auto shut off for low oil. The premium alternator provides low harmonic distortion. The large 7 Gal. tank with fuel gauge runs up to 15 hours at 50% load. Features include a hydraulic/magnetic circuit breaker that provides overload protection, a digital hour meter for monitoring run time and tracking maintenance and an idle control to reduce noise and save fuel. The steel frame is job site tested and includes a lifting hook. An optional wheel kit is available. (source: Dewalt (opens in a new tab))

Zoom on the Dewalt DXGN4500

In summary, the Dewalt DXGN4500 is a portable generator especially useful for:

  • RV travellers who wish to upgrade their experience to another level
  • People occasionally participating in outdoor fairs, festivals or events
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Professionals in need of safely powering high-intensity work or lighting equipment

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The Dewalt DXGN4500's engine, 270 cc (8.5 hp) Honda GX270 OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 4200W and reaches a peak wattage of 4500W.

Enjoying a noise rating of 76 dBA (less noisy than a dishwasher), this generator gets running thanks to a conventional pull-start mechanism.

Thanks to a fuel capacity of 7 gallons, the DXGN4500 can operate for around 15 hours at 50% load with a full tank (fuel consumption around 0.47 GPH).

The DXGN4500 is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<6%).

Outlets

The control panel provides the upcoming 6 AC outlets:

Two Duplexes 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle
120/240V 20A (L14-20R) receptacle

Even if this Dewalt generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor, thanks to its L5-30R receptacle.

Portability

The design of the Dewalt DXGN4500 is a typical, open frame, with the dimensions of L28.2 x W21.3 x H24.1 in, offering support and stability and enabling the possibility of raising it above ground level. The design is ideal for rough environments and demanding outdoor use.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 160 lbs make it incredibly difficult to manually lift and transport.

A lift hook located on the top of the frame offers an additional safety feature while facilitating the transport, loading and unloading of the generator.

Features

The control panel of the DXGN4500 includes a digital data center, which assists you in monitoring its status and activity, as it provides information on the lifetime run hours.

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off and an overload protection (circuit breaker).

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Dewalt DXGN4500 also is packed along with the following accessories: tool kit and oil.

Emissions

The Dewalt DXGN4500 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, making it usable in forested areas.

The Dewalt DXGN4500 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Dewalt DXGN4500 compare to generators of similar power (between 3500 and 4500 W).

  • With its weight of 160 lbs, the Dewalt DXGN4500 is one of the heavier generators in the 3500-4500 rated wattage category. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
  • If compared to generators capable of producing a similar running wattage, this generator with a lowest emitted noise of 76 dBA can be considered somewhat noisy. If you are concerned with noise, check out the Cummins Onan P4500i, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
  • Thanks to an impressive running time of around 15 hours at 50% load, the DXGN4500 benefits from a higher run time than many generators of a similar output. 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.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about 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 0.47 GPH. If you wish to further improve in the area of fuel efficiency, the Westinghouse iGen4200, which boasts with a gas consumption of only 0.17 GPH, may be the right generator for you.

The bottom line

STRENGTHS:
  • Several accessories included
  • GFCI Outlets
  • Honda engine
  • High run time
WEAKNESSES:
  • No electric start
  • On the heavy side (160 lbs)
  • On the noisy side (76 dBA)
  • Low fuel efficiency
