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 (opens in a new tab))

Zoom on the Dewalt DXGNR4000

In a nutshell, the Dewalt DXGNR4000 is a portable generator mostly geared towards:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • Occasional participants of outdoor events, competitions, concerts and 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 following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

The Dewalt DXGNR4000's engine, 223 cc OHV 4-stroke, fueled by gasoline, can deliver 120V. It provides a running wattage of 4,000W and reaches a peak wattage of 5,000W.

The 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.

Outlets

The control panel includes 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. This type of design is ideal for tough environments and heavy outdoor use.

As the generator's weight is 119 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). Still, once it is on the ground, its wheel kit and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

Features

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 generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

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

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.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Dewalt DXGNR4000 also comes with several accessories, including: oil and funnel.

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).

  • Having a dry weight of 119 lbs, the Dewalt DXGNR4000 belongs in the expected weight range for generators which produce 3500 to 4500 rated watts. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
  • Regarding its autonomy, the autonomy of the DXGNR4000, reaching around 10 hours at a 50% load, can be considered as low end, compared to other products of a roughly equal output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Predator 4375, boasting with around 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. With an estimated gasoline consumption of 0.34 GPH (gallon per hour) at 50% load, this generator is among the more fuel efficient of the products in the above-mentioned wattage range. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.23 GPH, the Westinghouse iGen4500DF is a device you could look out for.

Price comparison

As you can see from this interactive 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.
