Zoom on the Dewalt DXGNR4000
In a nutshell, the Dewalt DXGNR4000 is a portable generator mostly geared towards:
- 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
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.
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.
The control panel features the following 5 AC outlets:
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.
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. 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, this lack of maneuverability is compensated by its wheel kit and its folding handle, with which you can conveniently shift it, once it's on the ground.
Monitoring of the DXGNR4000's status and activity is made possible by a digital data center, which provides information on the lifetime run hours and is one of the features of its control panel.
The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.
As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.
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).
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.
The Dewalt DXGNR4000 is CARB-compliant. Therefore, its sale and purchase are permitted in all of the 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).
- 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.
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
- Fuel efficient
- Decent weight (119 lbs)
