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.
Zoom on the Dewalt DXGNR4000
To sum up, the Dewalt DXGNR4000 is a portable generator tailored for:
- RV travellers looking for even more independence
- People occasionally participating in outdoor fairs, festivals or events
- Homeowners in need of an emergency backup power for their essentials
- Professionals who want to ensure that a power failure will not prevent them from working
In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device.
Power & Run Time
With a 223 cc OHV 4-stroke engine, the Dewalt DXGNR4000 operates on gasoline, providing 120V, with a running wattage of 4,000W and a starting wattage of 5,000W.
This generator gets running thanks to a conventional pull-start mechanism.
Thanks to its 3.4 gallons fuel tank, the DXGNR4000 can run continuously for around 10 hours at 50% load on a full tank (with an average fuel consumption of approximately 0.34 GPH).
Outlets
The control panel features the upcoming 5 AC outlets:
While this Dewalt generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor.
Portability
Measuring L23.7 x W23 x H21.4 in, the classic open frame build of the Dewalt DXGNR4000 delivers stability and easy maintenance access to components, facilitating air circulation. The design is ideal for rough environments and demanding outdoor use.
With a weight of 119 lbs, the generator is still labeled as 'portable,' denoting its ability to be moved, although its heaviness might restrict easy portability. However, the limited maneuverability is remedied with its wheel kit and its folding handle, facilitating convenient shifting once the generator is positioned on the ground.
Features
With a digital data center integrated into its control panel, the DXGNR4000 provides real-time insights into the lifetime run hours, enabling easy monitoring of its status and activity.
The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.
As far as security is concerned, the generator comes with an overload protection (circuit breaker) and an automatic low oil shut-off, providing peace of mind during 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.
Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Dewalt DXGNR4000's package also includes these 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).
- With a dry weight of 119 lbs, the Dewalt DXGNR4000 sits comfortably within the expected weight range for devices generating 3500 to 4500 rated watts. If you are mindful of weight, the WEN 56432iX is among the top contenders in this power range, with a dry weight of 52.9 pounds.
- The DXGNR4000, offering a run time of around 10 hours with a full tank at a 50% load, falls within the average autonomy range when compared to its peers. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the NorthStar c5500, boasting with around 15.1 hours.
- While run time is vital, it hinges on the fuel capacity. To grasp the full picture, we must also factor in fuel efficiency. As this generator uses an estimated 0.34 GPH (gallon per hour) at a 50% load, it finds itself in the average gasoline consumption range of similar products. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse iGen5000DF, with a fuel consumption of 0.23 GPH could be in your good books.
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.
