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
  • Occasional participants of outdoor events, competitions, concerts and festivals
  • Homeowners in need of an emergency backup power for their essentials
  • 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 DXGN4500 houses a 270 cc (8.5 hp) Honda GX270 OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 4,200W along with a peak wattage of 4,500W.

Enjoying a noise rating of 76 dBA (less noisy than a vacuum cleaner), this generator gets running thanks to a simple traditional 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 powering of sensitive electronic devices with the DXGN4500 is not recommended due to its relatively high THD (<6%).

Outlets

The control panel includes the following 6 AC outlets:

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

This Dewalt generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready.

Portability

The Dewalt DXGN4500 has a conventional, open frame design, of the following dimensions: L28.2 x W21.3 x H24.1 in, which offers support and allows it to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 160 pounds.

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.

From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Dewalt DXGN4500 also comes with several accessories, including: tool kit and oil.

Emissions

The Dewalt DXGN4500 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 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).

  • Considering its dry weight of 160 pounds, the Dewalt DXGN4500 is one of the heavier generators producing between 3500 and 4500 running watts. If you are concerned by weight, one of the champions in the above-mentioned power range is the WEN GN400i, with a dry weight of 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. For those who are looking for a less noisy device, we suggest the Westinghouse iGen4500DF. With just 52 dBA, it is one of the most quiet devices in this power range.
  • As the DXGN4500 features an autonomy of around 15 hours at 50% load, it has a higher run time than an average generator of its power range. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Predator 4375, which is able to run for around 16 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. Compared to its peers, this generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.47 GPH at a 50% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.23 GPH, the Westinghouse iGen4500DF is a device you could look out for.

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
