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
- People occasionally participating in sporting competitions, open-air performances and outdoor festivals
- 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
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 is powered by a 223 cc OHV 4-stroke engine. It delivers 120V, runs on gasoline and offers a running wattage of 4,000W as well as a peak wattage of 5,000W.
Its starting mechanism is based on 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 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.
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.
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, its challenging mobility is solved by its wheel kit and its folding handle, which will ease its displacement, once it is on the floor.
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.
Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the Dewalt DXGNR4000 also comes with some accessories: oil and funnel are included.
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 and thus, may be used 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. In terms of weight, one of the champions in their power range is the WEN GN400i, standing at just 66.1 lbs.
- As far as autonomy is concerned, providing around 10 hours of runtime with a full tank at a 50% load, the DXGNR4000 falls into the low end in comparison with other devices of a comparable power 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.
- Run times are important, yet thanks to their dependence on the fuel capacity, they should be judged along with the fuel consumption of the device. 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 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.
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
- Several accessories included
- GFCI Outlets
- Decent weight (119 lbs)
- Decent fuel efficiency
- No electric start
