Zoom on the Dewalt DXGNR4000
In a nutshell, the Dewalt DXGNR4000 is a portable generator mostly geared towards:
- RV travellers looking for even more independence
- People occasionally participating in outdoor fairs, festivals or events
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- Professionals who want to ensure that a power failure will not prevent them from working
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.
Power & Run Time
The Dewalt DXGNR4000 houses a 223 cc OHV 4-stroke engine, which provides 120V, consumes gasoline and delivers a running wattage of 4000W along with a peak wattage of 5000W.
This generator features a conventional pull-start mechanism.
The fuel capacity of 3.4 gallons allows the DXGNR4000 to operate for around 10 hours at 50% load with a full tank (fuel consumption around 0.34 GPH).
The control panel features the upcoming 5 AC outlets:
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.
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 design is ideal for rough environments and demanding 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. However, its challenging mobility is solved by its wheel kit and its folding handle, which will ease its displacement, once it is on the floor.
To help you monitor the DXGNR4000's status and activity, its control panel is equipped with a digital data center, giving you information on the lifetime run hours.
The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a 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 (opens in a new tab).
Besides the usual set of documentation and owner's manual to get you promptly started, Dewalt also included some oil in the DXGNR4000's packaging.
The Dewalt DXGNR4000 is CARB-compliant. It can therefore be sold and purchased in all 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).
- With a dry weight of 119 pounds, the Dewalt DXGNR4000 finds itself in the expected weight range for generators able to produce between 3500 and 4500 rated watts. Regarding dry weight, one of the champions in the same power range is the WEN GN400i, with a dry weight of only 66.1 lbs.
- 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 autonomy is your priority, one of the devices of a similar power output with the highest run time is the Honda EB4000X, reaching 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. This generator has an average fuel consumption among comparably powerful devices, as it reaches 0.34 GPH (gallon per hour) at a 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4200. With a fuel consumption of as little as 0.17 GPH, it is one of the most efficient generators currently on the market.
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.
The bottom line
- In the expected price range
- CO Protect technology
- GFCI Outlets
- Decent weight (119 lbs)
- Decent fuel efficiency
- No electric start
- Relatively low run time
