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 a nutshell, the Dewalt DXGN4500 is a portable generator mostly geared towards:

  • RV travellers who wish to upgrade their experience to another level
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Professionals who want to ensure that a power failure will not prevent them from working

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 parameters.

Power & Run Time

The Dewalt DXGN4500's build contains a gasoline-fueled 270 cc (8.5 hp) Honda GX270 OHV 4-stroke engine. With a 120/240V output, it gives a running wattage of 4200W and also a peak wattage of 4500W.

At a noise rating of 76 dBA (less noisy than a vacuum cleaner), the generator offers the possibility to start the device via a conventional pull-start mechanism.

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

The quite high THD (<6%) of the DXGN4500 makes it unsuitable for powering sensitive of electronic devices.

The following are examples of possible devices which the generator will allow you to power simultaneously:Note: The examples above are based on a maximum load of 75% and estimated wattages. The devices also may not be able to start at the same time. For a more accurate estimation, use our wattage calculator.

Outlets

The control panel features the upcoming 6 AC outlets:

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

While this Dewalt generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor.

Portability

The Dewalt DXGN4500 has the following dimensions: L28.2 x W21.3 x H24.1 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. 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 160 pounds.

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.

Features

To help you monitor the DXGN4500's status and activity, its control panel is equipped with .

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to use it with a peace of mind.

Along the basic documentation and a user manual, useful for starting the generator right away, the Dewalt DXGN4500's package also includes these accessories: oil and tool kit.

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 and therefore, can be used 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. Regarding dry weight, one of the champions in the same power range is the Energizer eZV4500, with a dry weight of only 78 lbs.
  • As this generator has its lowest possible noise of 76 dBA, it should be considered noisier compared to its peers of a comparable running wattage. If noise emissions are one of your priorities, you may be interested in the Westinghouse iGen4500, one of the least noisy generators similarly powerful as this one, rated for 52 dBA.
  • As the DXGN4500 features an autonomy of 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 Honda EB4000, which is able to run for 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. This generator is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.47 GPH at a 50% load. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen4200, which has a fuel consumption of only 0.17 GPH and thus, is one of the most efficient devices in our database.

Price comparison

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

Therefore, this generator nicely fits in the expected budget for this kind of product.

The bottom line

STRENGTHS:
  • In the expected price range
  • Several accessories included
  • Honda engine
  • High run time
WEAKNESSES:
  • No electric start
  • On the heavy side (160 lbs)
  • On the noisy side (76 dBA)
