Zoom on the Dewalt DXGN4500
In a nutshell, the Dewalt DXGN4500 is a portable generator mostly geared towards:
- RV travellers looking for even more independence
- 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 DXGN4500 is powered by a 270 cc (8.5 hp) Honda GX270 OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 4200W as well as a peak wattage of 4500W.
At a noise rating of 76 dBA (less noisy than a dishwasher), the generator is started via a conventional pull-start mechanism.
Thanks to a fuel capacity of 7 gallons, the DXGN4500 can operate for around 15 hours at 50% load with a full tank (fuel consumption around 0.47 GPH).
The quite high THD (<6%) of the DXGN4500 makes it unsuitable for powering sensitive electronic devices.
The control panel provides the upcoming 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 device has been designed for tough 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).
The generator comes with an additional safety feature, a lift hook on the top of its frame, which is helpful during its transport, loading and unloading.
To help you monitor the DXGN4500's status and activity, its control panel is equipped with a digital data center, giving you information on the lifetime run hours.
The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.
Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.
With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the Dewalt DXGN4500 also comes with several accessories, including: tool kit and oil.
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. If weight is your top priority, one of the champions in this power category is the WEN GN400i, weighing just 66.1 pounds.
- This generator, with its lowest possible noise rated at 76 dBA falls into the more noisy category, compared to other devise of a similar running wattage. If you are concerned with noise, check out the Cummins Onan P4500i, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
- Since the DXGN4500 boasts with a run time of around 15 hours at 50% load, it can be safely judged as a device of a higher run time than most generators of a comparable output. 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.
- 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. In fact, this generator is not among the most fuel efficient, within the aforementioned wattage range : its estimated gasoline consumption at 50% load is around 0.47 GPH. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Westinghouse iGen4200. With a fuel consumption of as little as 0.17 GPH, it is one of the most efficient generators currently on the market.
As you can see from this interactive chart, when compared to other 3500-4500W generators, the Dewalt DXGN4500 is on the expensive side of the price range.
While certainly not the cheapest of its kind, purchasing it would most likely also mean enjoying the reliability of a high-end product.
