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 short, the Dewalt DXGNR4000 is a portable generator adequately designed for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • People occasionally participating in outdoor fairs, festivals or events
  • Homeowners in need of an emergency backup power for their essentials
  • Professionals in need of safely powering high-intensity work or lighting equipment

Over the following sections, you'll uncover its power characteristics, the selection of outlets it offers, its overall portability, and the supplementary features it includes.

Power & Run Time

Dewalt DXGNR4000 is equipped with a 223 cc OHV 4-stroke engine, running on gasoline and providing 120V, boasting a running wattage of 4,000W alongside a starting wattage of 5,000W.

This generator utilizes a traditional recoil pull-start mechanism for startup.

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

Outlets

The control panel features 5 AC outlets as follows:

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

Despite not having the 'RV Ready' status, this Dewalt generator provides the benefit of convenient RV compatibility through its L5-30R receptacle, enabling you to easily power your RV using an L5-30P to TT-30R adaptor.

Portability

With dimensions of L23.7 x W23 x H21.4 in, the standard open frame design of the Dewalt DXGNR4000 provides stability and easy maintenance access to components, as well as good air circulation. This type of design is ideal for tough environments and heavy outdoor use.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 119 pounds. Nonetheless, the limited maneuverability is compensated for by utilizing its wheel kit and its folding handle, which facilitates shifting once the generator is set on the ground.

Features

The DXGNR4000's control panel

A digital data center, one of the features of the DXGNR4000's control panel, gives you information on the lifetime run hours, and thus, is helpful for the monitoring of its activity and status.

Thanks to its built-in fuel gauge, the generator allows you to quickly, conveniently, and easily check the gas level at a glance.

In terms of security, the generator features an overload protection (circuit breaker) and an automatic low oil shut-off, ensuring peace of mind during its use.

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.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Dewalt DXGNR4000 also is packed along with the following accessories: funnel and oil.

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).

  • At 119 lbs in dry weight, the Dewalt DXGNR4000 fits well within the typical weight bracket for generators producing 3500 to 4500 rated watts. If weight matters to you, one of the champions in this power range is the Genmax GM4600iAEFIC with only 58.4 pounds.
  • As for its runtime, the DXGNR4000 runs for around 10 hours at a 50% load, placing it towards the low end among comparable products. 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, with an estimated fuel consumption of just 0.34 GPH (gallon per hour) at 50% load, is one of the more fuel-efficient generators, for the previously mentioned wattage range. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen4500DF, which has a fuel consumption of only 0.23 GPH and thus, is one of the most efficient devices in our database.

Price comparison

As you can see from these interactive charts, when compared to other 3500-4500W generators, the Dewalt DXGNR4000 is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.

SAE 10W-30 is recommended for general, all temperature use.

What gasoline is the best (Asked January 13, 2021)

Gasoline should be clean, fresh, and unleaded, with a minimum octane rating of 87.

How much oil does this take? (Asked February 01, 2021)

Engine oil capacity is 0.54 qt.
