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.

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
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • Homeowners in need of an emergency backup power for their essentials
  • Professionals who want to ensure that a power failure will not prevent them from working

The subsequent sections will explore in detail its power characteristics, the diverse outlets it provides, its overall portability, and the supplementary features it offers.

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.

Rated for 76 dBA (less noisy than a shower), the generator's starting mechanism relies on a manual recoil starter system.

The DXGN4500's fuel tank, with a capacity of 7 gallons, supports uninterrupted operation for around 15 hours at 50% load when fully fueled (fuel consumption at an estimated 0.47 gallons per hour).

As the DXGN4500 has a relatively high THD (<6%), it is not recommended to use it to power sensitive electronic devices.

Outlets

The control panel features 6 AC outlets as follows:

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

Even though this Dewalt generator isn't quite RV Ready, its L5-30R receptacle allows an easy RV connection via an L5-30P to TT-30R adaptor.

Portability

With dimensions of L28.2 x W21.3 x H24.1 in, the traditional open frame design of the Dewalt DXGN4500 ensures stability while allowing easy maintenance access to components and promoting effective air cooling. The device has been designed for tough environments and demanding outdoor use.

As the generator's weight is 160 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable).

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

The DXGN4500's control panel is equipped with a digital data center, furnishing detailed information on the lifetime run hours for you to easily track its activity and status.

Featuring a built-in fuel gauge, the generator offers quick, convenient, and easy gas level checks at a glance.

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

In addition to the traditional documentation and an owner's manual (opens in a new tab) to help you get started promptly, the Dewalt DXGN4500 also includes several 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).

  • Considering its dry weight of 160 pounds, the Dewalt DXGN4500 is one of the heavier generators producing between 3500 and 4500 running watts. If weight is an important consideration for you, the WEN 56432iX stands out as one of the top contenders in this power category, with a dry weight of 52.9 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 you'd like a less noisy alternative, the Westinghouse iGen5000DF is a strong contender. It boasts a noise rating of 52 dBA, placing it among the quietest generators in its power category.
  • With around 15 hours of runtime at 50% load, the DXGN4500 provides a higher run time when compared to similarly powerful products. If extended autonomy is what matters most to you, the NorthStar c5500 could be an excellent choice, offering one of the longest run times among units in its power category, reaching around 15.1 hours.
  • Though run time is a significant parameter, it's closely tied to the generator's fuel tank size. To get a comprehensive understanding, fuel efficiency must also be taken into account. In fact, this generator is not one of the most fuel-efficient options in the aforementioned wattage range: its estimated gasoline consumption at 50% load is around 0.47 GPH. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen5000DF, with a fuel consumption of 0.23 GPH could be in your good books.

The bottom line

STRENGTHS:
  • GFCI Outlets
  • Honda engine
  • High run time
WEAKNESSES:
