Zoom on the Dewalt DXGN4500
In summary, the Dewalt DXGN4500 is a portable generator especially useful for:
- RV travellers who wish to upgrade their experience to another level
- People occasionally participating in sporting competitions, open-air performances and outdoor 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's engine, 270 cc (8.5 hp) Honda GX270 OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 4200W and reaches a peak wattage of 4500W.
With a noise rating of 76 dBA (less noisy than a shower), the generator features a conventional pull-start mechanism.
The DXGN4500 can operate for around 15 hours at 50% load with a full tank (fuel consumption around 0.47 GPH), due to its fuel capacity of 7 gallons.
The powering of sensitive electronic devices with the DXGN4500 is not recommended due to its relatively high THD (<6%).
The control panel includes the following 6 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 Dewalt DXGN4500 has a conventional, open frame design, of the following dimensions: L28.2 x W21.3 x H24.1 in, which offers support and allows it to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.
As the generator's weight is 160 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable).
In addition, the device is equipped with a lift hook on the top of its frame, which provides extra safety during the loading, unloading and transport of the generator.
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.
A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.
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.
Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the Dewalt DXGN4500's package also includes these accessories: oil and tool kit.
The Dewalt DXGN4500 is EPA-approved and 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 therefore, can be used 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).
- With its weight of 160 lbs, the Dewalt DXGN4500 is one of the heavier generators 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.
- If compared to generators capable of producing a similar running wattage, this generator with a lowest emitted noise of 76 dBA can be considered somewhat noisy. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the Cummins Onan P4500i, whose lowest noise levels reach just 52 dBA.
- As the DXGN4500 features an autonomy of around 15 hours at 50% load, it has a higher run time than an average generator of its power range. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Honda EB4000X, boasting with around 16 hours.
- Autonomy holds its importance, however, it is largely dependent on the generator’s fuel capacity and so, it is nonsensible to discuss it without mentioning fuel efficiency as well. Compared to its peers, this generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.47 GPH at a 50% load. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen4200, which has a fuel consumption of only 0.17 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 DXGN4500 is on the average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
