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 a few words, the Dewalt DXGN4500 is a portable generator perfectly suited for:

  • RV travellers looking for even more independence
  • 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 who want to ensure that a power failure will not prevent them from working

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed.

Power & Run Time

The Dewalt DXGN4500's design includes 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 4,200W and also a peak wattage of 4,500W.

The generator features a conventional pull-start mechanism. It is rated for a noise of 76 dBA (less noisy than a shower).

With a fuel capacity of 7 gallons, the DXGN4500 may run for around 15 hours at 50% load with a full tank (fuel consumption around 0.47 GPH).

Due to the relatively high THD (<6%) of the DXGN4500, it is advised against using it for powering sensitive electronic devices.

Outlets

The control panel features the following 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

Measuring L28.2 x W21.3 x H24.1 in, the classic open frame construction of the Dewalt DXGN4500 provides stability while enabling convenient maintenance access to components and adequate air cooling. The design is ideal for rough environments and demanding outdoor use.

While weighing 160 lbs, the generator is classified as 'portable,' indicating its mobility, albeit its heftiness may limit portability in specific situations.

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

Designed with a digital data center, the control panel of the DXGN4500 grants you access to crucial data on the lifetime run hours, ensuring practical monitoring of its status and activity.

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

Regarding security, the generator comes with an automatic low oil shut-off and an overload protection (circuit breaker), providing peace of mind during operation.

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.

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 160 lbs, the Dewalt DXGN4500 stands out as one of the heavier generators rated from 3500 to 4500. If weight is your top priority, one of the champions in this power category is the Genmax GM4600iAEFIC, weighing just 58.4 pounds.
  • 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 is a concern for you, you could consider the Westinghouse iGen4500DF, which is one of the least noisy generators in its power range, rated at 52 dBA.
  • Compared to devices of similar power, the DXGN4500 stands out with one of the higher run times, lasting around 15 hours at 50% load. If prolonged run time is essential to your needs, you could consider the Predator 4375, which offers one of the highest autonomy among devices with similar power output, lasting around 16 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. When it comes to fuel efficiency among generators with similar wattage, this generator lags behind, with a consumption rate of 0.47 GPH at a 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4500DF. With a fuel consumption of as little as 0.23 GPH, it is one of the most efficient generators currently on the market.
