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)

Zoom on the Dewalt DXGN4500

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

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Homeowners in need of an emergency backup power for their essentials
  • 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 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 4200W along with a peak wattage of 4500W.

The generator is rated for a noise of 76 dBA (less noisy than a shower). Its starting mechanism is based on 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 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

With its dimensions of L28.2 x W21.3 x H24.1 in, the conventional, open frame design of the Dewalt DXGN4500 offers stability and allows the generator to be raised above ground level. The design is ideal for rough 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 160 pounds.

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

To help you monitor the DXGN4500's status and activity, its control panel is equipped with a digital data center, giving you information on the lifetime run hours.

The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

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

Apart from the typical documentation and a user manual, 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. Thus, selling and purchasing this generator is allowed in each 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).

  • At a dry weight of 160 pounds, the Dewalt DXGN4500 is one of the heavier devices which can produce between 3500 and 4500 running watts. In terms of weight, one of the champions in their power range is the WEN GN400i, standing at just 66.1 lbs.
  • 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’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Westinghouse iGen4500, whose lowest noise levels reach just 52 dBA.
  • The DXGN4500 provides a higher run time than similarly powerful devices, reaching around 15 hours at 50% load. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Honda EB4000, as it provides 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. This generator is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 0.47 GPH at a 50% load. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.17 GPH, the Westinghouse iGen4200 is a device you should look out for.

Price comparison

As you can see from this dynamic chart, when compared to other 3500-4500W generators, the Dewalt DXGN4500 is on the expensive side of the price range.

While certainly not the cheapest of its kind, purchasing it would most likely also mean enjoying the reliability of a high-end product.

The bottom line

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