  • DIYers who wish to improve their efficiency with tools
  • Homeowners in need of an emergency backup power for their essentials
  • Professionals who want to be able to deliver results, even during a power failure

In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.

Power & Run Time

The DuroStar DS4500DX in use

The DuroStar DS4500DX

With its dual-fuel technology, the powerful and versatile DuroStar DS4500DX provides an output of 120/240V. While gasoline-powered, it gives a running wattage of 3500W along with a peak wattage of 4500W. While propane-powered, it provides 3325 rated watts and 4275 starting watts.

The generator features a conventional pull-start mechanism and also a simple and elegant electric starter (battery included). It is rated for a noise of 69 dBA (less noisy than background music).

As for its running time, the DS4500DX, along with its 4 gallons fuel capacity, can run for around 10.4 hours at 50% load with a full tank filled with gasoline (fuel consumption around 0.38 GPH). If propane is used, it can operate for around 8.9 hours (on a 20 lbs tank - propane consumption around 0.53 GPH).

As the DS4500DX has a relatively high THD (<12%), it is not recommended to use it to power sensitive electronic devices.

Outlets

The control panel features the upcoming 3 AC outlets:

Duplex 120V 20A (5-20R) GFCI
120/240V 30A (L14-30R) receptacle

Because the DS4500DX is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.

Portability

The dimensions of the DuroStar DS4500DX, which are L25 x W23 x H22 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The device has been designed for tough environments and demanding outdoor use.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 126 pounds. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit and its folding handle, once it is placed on the ground.

Features

The DS4500DX's control panel

To help you monitor the DS4500DX's status and activity, its control panel is equipped with a convenient meter, which displays voltage, frequency and lifetime hours.

In addition to this info, when its oil levels are insufficient, you will be informed by the featured light indicator.

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

Security-wise, this product benefits from an overload protection (circuit breaker) and an automatic low oil shut-off, which gives you a complete peace of mind when using it.

The DS4500DX also benefits from DuroStar’s CO Alert carbon monoxide shutdown. If CO levels become unsafe or rapidly increase, the generator will automatically shut down, an indicator will light red, and the engine will not restart for 5 minutes. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the DuroStar DS4500DX's package also includes these accessories: funnel, tool kit and propane hose.

Emissions

The DuroStar DS4500DX 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, so it is adequate for use in forested areas.

The DuroStar DS4500DX versus other generators

The following charts are provided to give you an idea of how some of the key specs of the DuroStar DS4500DX compare to generators of similar power (between 3000 and 4000 W).

  • With its weight of 126 lbs, the DuroStar DS4500DX is one of the heavier generators in the 3000-4000 rated wattage category. If weight is your top priority, one of the champions in this power category is the Genmax GM3300i, weighing just 47.4 pounds.
  • Among the generators of a comparable running wattage, this generator with a lowest noise of 69 dBA can be judged as noisy. If you are concerned with noise, check out the Cat INV4000E, which is one of the least noisy generators in its power range, with a noise rating of just 51 dBA.
  • As the DS4500DX offers around 10.4 hours run time on a full tank at a 50% load, it falls within the average autonomy range among the generators of a similar power. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Predator 4375, as it provides 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. This generator has an estimated fuel consumption of roughly 0.38 GPH (gallon per hour) at a 50% load, rendering it somewhat average compared to devices of a similar output. 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.
