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 looking for even more independence
  • People occasionally participating in outdoor fairs, festivals or events
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Professionals in need of safely powering high-intensity work or lighting equipment

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 is powered by a 270 cc (8.5 hp) Honda GX270 OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 4,200W as well as a peak wattage of 4,500W.

Operating at a noise rating of 76 dBA (less noisy than a vacuum cleaner), this generator starts up with a conventional pull-start mechanism.

Thanks to its 7 gallons fuel tank, the DXGN4500 can run continuously for around 15 hours at 50% load on a full tank (with an average fuel consumption of approximately 0.47 GPH).

Since the DXGN4500 has a somewhat high THD (<6%), it is advisable to not use it for the powering of sensitive electronic devices.

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

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 L28.2 x W21.3 x H24.1 in dimensions, the open frame structure of the Dewalt DXGN4500 guarantees stability, simplified maintenance access to components, and better air cooling than enclosed units. This type of design is ideal for tough environments and heavy outdoor use.

Even at 160 lbs, the generator is categorized as 'portable,' suggesting its movability, although its weight impede its portability.

In addition, the device is equipped with a lift hook on the top of its frame, which provides extra safety during the loading, unloading and transport of the generator.

Features

For easy status and activity monitoring of the DXGN4500, its control panel integrates a digital data center, offering insights into the lifetime run hours.

Benefiting from its built-in fuel gauge, the generator allows for easy and immediate gas level inspections.

From a security standpoint, the generator is furnished with an automatic low oil shut-off and an overload protection (circuit breaker), ensuring peace of mind during operation.

Beyond the standard documentation and an owner's manual (opens in a new tab) to assist with setup, the Dewalt DXGN4500 ships with supplementary 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).

  • Weighing in at 160 lbs, the Dewalt DXGN4500 is one of the heavier generators available in the 3500-4500 rated wattage segment. Weight-conscious users may find the Genmax GM4600iAEFIC appealing, as it is one of the top contenders in this power range, weighing just 58.4 pounds.
  • When stacked up against other devices of similar running wattage, this generator's lowest possible noise rating of 76 dBA places it in the louder category. If noise level is one your key decisive factors, you may find the Westinghouse iGen5000DF appealing. It's rated at 52 dBA, making it one of the quietest generators in its 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. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Predator 4375, with 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. This generator is somewhat less fuel-efficient than devices of comparable output: its estimated fuel consumption reaches 0.47 GPH at a 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen5000DF. With a fuel consumption of as little as 0.23 GPH, it is one of the most efficient generators currently on the market.
