Zoom on the Dewalt DXGN4500
In a nutshell, the Dewalt DXGN4500 is a portable generator mostly geared towards:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- Occasional participants of outdoor events, competitions, concerts and festivals
- Homeowners in need of an emergency backup power for their essentials
- Professionals in need of safely powering high-intensity work or lighting equipment
Power & Run Time
The Dewalt DXGN4500 houses a 270 cc (8.5 hp) Honda GX270 OHV 4-stroke engine, which provides 120/240V, consumes gasoline and delivers a running wattage of 4200W along with a peak wattage of 4500W.
At a noise rating of 76 dBA (less noisy than a shower), the generator is started via a simple traditional pull-start mechanism.
With a full tank, the DXGN4500 can operate for around 15 hours at 50% load (fuel consumption around 0.47 GPH), thanks to its fuel capacity of 7 gallons.
Since the DXGN4500 has a somewhat high THD (<6%), it is advisable to not use it for the powering of sensitive electronic devices.
The control panel provides the upcoming 6 AC outlets:
This Dewalt generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready.
The Dewalt DXGN4500 has the following dimensions: L28.2 x W21.3 x H24.1 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.
Since the generator weighs 160 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable).
Further safety during transport, loading and unloading of the device is provided by a lift hook, which is placed on the top of the generator's frame.
One of the many DXGN4500'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.
From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.
While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the Dewalt DXGN4500, the following accessories are also included: oil and tool kit.
The Dewalt DXGN4500 is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.
Moreover, it features a spark arrestor, which makes it suitable for use in forested areas.
The Dewalt DXGN4500 versus other generators
The following charts are provided to give you an idea of how some of the key specs of the Dewalt DXGN4500 compare to generators of similar power (between 3500 and 4500 W).
- As its dry weight is 160 pounds, the Dewalt DXGN4500 is one of the heavier of the products which can generate 3500 to 4500 running 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.
- Among the generators of a comparable running wattage, this generator with a lowest noise of 76 dBA can be judged as noisy. For those who are looking for a less noisy device, we suggest the Cummins Onan P4500i. With just 52 dBA, it is one of the most quiet devices in this power range.
- The DXGN4500 provides a higher run time than similarly powerful devices, reaching around 15 hours at 50% load. 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.
- 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 is somewhat less fuel efficient than devices of comparable output: its estimated fuel consumption reaches 0.47 GPH at a 50% load. If you wish to further improve in the area of fuel efficiency, the Westinghouse iGen4200, which boasts with a gas consumption of only 0.17 GPH, may be the right generator for you.
As you can see from this interactive chart, when compared to other 3500-4500W generators, the Dewalt DXGN4500 is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
