Description

The 4000 Watt Portable Gas Generator is powered by a 223cc engine with low oil shut off which protects the engine from damage. CO-Protect Technology automatically shuts down the generator if carbon monoxide levels become unsafe or rapidly increase. This generator is equipped with covered outlets to help protect it from even the toughest jobsites and features heavy duty wheels for transportation and durability. The 3.4 Gal. steel fuel tank provides up to 10 hours of runtime at 50% load. The 1 ¼” steel tube frame helps protect it from jobsite conditions. (source: Dewalt)

Zoom on the Dewalt DXGNR4000

In summary, the Dewalt DXGNR4000 is a portable generator especially useful for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Professionals who want to be able to deliver results, even during a power failure

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 DXGNR4000's build contains a gasoline-fueled 223 cc OHV 4-stroke engine. With a 120V output, it gives a running wattage of 4000W and also a peak wattage of 5000W.

This generator features a conventional pull-start mechanism.

With a full tank, the DXGNR4000 can operate for around 10 hours at 50% load (fuel consumption around 0.34 GPH), thanks to its fuel capacity of 3.4 gallons.

Several examples of what the generator may allow you to power simultaneously are:Note: All of these devices might not start simultaneously. Provided examples are based on a maximum load of 75 % and estimated wattages. With the help of our wattage calculator you can find out if this product suits your requirements.

Outlets

The control panel features the following 5 AC outlets:

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

This Dewalt generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor.

Portability

The dimensions of the Dewalt DXGNR4000, which are L23.7 x W23 x H21.4 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The generator is designed for ideal use outdoors and in rough environments.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 119 lbs. However, this lack of maneuverability is compensated by a wheel kit and a folding handle, with which you can conveniently displace it, once it's on the ground.

Features

Panel of the Dewalt DXGNR4000

The DXGNR4000's control panel

One of the many DXGNR4000's features is the data center, included in its control panel, which conveniently provides information on the lifetime run hours and thus, helps you monitor its activity and status.

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.

The DXGNR4000 also benefits from Dewalt’s CO Protect carbon monoxide shutdown. If CO levels become unsafe or rapidly increase, the generator is automatically shut down. It’s a welcomed additional security feature, but don’t forget to always take your generator outside.

Besides the usual set of documentation and user manual to get you promptly started, Dewalt also included some oil in the DXGNR4000's packaging.

Emissions

The Dewalt DXGNR4000 is 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 DXGNR4000 versus other generators

The following charts are provided to give you an idea of how some of the key specs of the Dewalt DXGNR4000 compare to generators of similar power (between 3500 and 4500 W).

  • Since the generator weighs in at a dry weight of 119 lbs, the Dewalt DXGNR4000 belongs in the expected weight range for devices which can produce between 3500 and 4500 rated watts. If you are concerned by weight, one of the champions in the above mentioned power range is the WEN GN400i, with a dry weight of just 66.1 pounds.
  • Autonomy-wise, with 10 hours on a full tank at a 50% load, the DXGNR4000 is on the low end when compared to other generators of a similar power output. 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 Honda EB4000, with 16 hours .
  • Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. As this generator uses an estimated 0.34 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen4200, with a fuel consumption of 0.17 GPH could be in your good books.

Price comparison

As you can see from this dynamic chart, when compared to other 3500-4500W generators, the Dewalt DXGNR4000 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
  • CO Protect technology
AVERAGE SPECS:
  • Decent weight (119 lbs)
  • Decent fuel efficiency
WEAKNESSES:
  • No electric start
  • Relatively low run time
