Zoom on the Dewalt DXGN4500
In summary, the Dewalt DXGN4500 is a portable generator especially useful for:
- RV travellers wishing to enhance their freedom and nomad lifestyle
- Occasional participants of outdoor events, competitions, concerts and festivals
- Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
- 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.
Enjoying a noise rating of 76 dBA (less noisy than a vacuum cleaner), this generator gets running thanks to a simple traditional pull-start mechanism.
The fuel capacity of 7 gallons allows the DXGN4500 to operate for around 15 hours at 50% load with a full tank (fuel consumption around 0.47 GPH).
The DXGN4500 is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<6%).
The control panel includes the following 6 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.
With its dimensions of L28.2 x W21.3 x H24.1 in, the conventional, open frame design of the Dewalt DXGN4500 offers stability and allows 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.
Monitoring of the DXGN4500'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 includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.
Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the Dewalt DXGN4500 also is packed along with the following accessories: oil and tool kit.
The Dewalt DXGN4500 is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 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).
- At a dry weight of 160 pounds, the Dewalt DXGN4500 is one of the heavier devices which can produce between 3500 and 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.
- 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’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.
- The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. This generator is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.47 GPH at a 50% load. 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 average side of the price range.
Therefore, this generator nicely fits in the expected budget for this kind of product.
