Zoom on the Dewalt DXGNR4000
In summary, the Dewalt DXGNR4000 is a portable generator especially useful for:
- RV travellers who wish to upgrade their experience to another level
- Occasional participants of outdoor events, competitions, concerts and festivals
- Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
- Professionals in need of safely powering high-intensity work or lighting equipment
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 core is the 223 cc OHV 4-stroke engine, which runs on gasoline. With an output of 120V, it provides a running wattage of 4000W and a peak wattage of 5000W.
The generator features a simple traditional 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 following 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 Dewalt DXGNR4000 has a conventional, open frame design, of the following dimensions: L23.7 x W23 x H21.4 in, which offers support and allows it 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. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit and its folding handle, once it is placed on the ground.
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.
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 overload protection (circuit breaker) and an automatic low oil shut-off, 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. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).
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 is CARB-compliant. It can therefore be sold and purchased in all 50 states, including California.
Moreover, it features a spark arrestor, making it usable 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).
- As its weight is 119 pounds, the Dewalt DXGNR4000 falls in the expected weight range of the devices in the 3500-4500 rated wattage category. In terms of weight, one of the champions in their power range is the WEN GN400i, standing at just 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 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 has an estimated fuel consumption of roughly 0.34 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. 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.
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)
