Zoom on the DuroStar DS4500DX

In summary, the DuroStar DS4500DX 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
  • Amateur DIY lovers
  • Homeowners who want to be sure of their ability to power their fridges, cooking tools, heating and lighting equipment during power failures
  • Professionals who want to ensure that a power failure will not prevent them from working

The subsequent sections will explore in detail its power characteristics, the diverse outlets it provides, its overall portability, and the supplementary features it offers.

Power & Run Time

The DuroStar DS4500DX in use

The DuroStar DS4500DX

The dual-fuel technology of the DuroStar DS4500DX allows for an output of 120/240V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 3,500W and a starting wattage of 4,500W. If propane-powered, it gives 3,325 rated watts and 4,275 starting watts.

Enjoying a noise rating of 69 dBA (less noisy than an office), this generator offers the versatility of starting with either a simple traditional pull-start mechanism or an intuitive and practical electric starter (battery included).

Regarding its running time, the DS4500DX, with a 4 gallons fuel tank, can operate for up to 25 hours with a full gasoline tank (with fuel consumption estimated at around 0.16 gallons per hour). It also offers up to 20 hours (on a 20 lbs tank - propane consumption around 0.24 GPH) of operation when using propane.

As the DS4500DX exhibits a THD of less than 12%, which is relatively high, it is best avoided for powering sensitive electronic devices.

Outlets

The control panel features the following 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

With dimensions of L25 x W23 x H22 in, the traditional open frame design of the DuroStar DS4500DX ensures stability while allowing easy maintenance access to components and promoting effective air cooling. The design is ideal for rough environments and demanding outdoor use.

Even at 126 lbs, the generator is categorized as 'portable,' suggesting its movability, although its weight impede its portability. Nonetheless, the limited maneuverability is compensated for by utilizing its wheel kit (⌀8") and its folding handle, which facilitates shifting once the generator is set on the ground.

Features

Panel of the DuroStar DS4500DX

The DS4500DX's control panel

The control panel of the DS4500DX includes a convenient meter, displaying voltage, frequency, and lifetime hours information, helpful for the monitoring of its status and activity.

In addition to this info, the device’s light indicator will display if the oil level is too low.

Benefiting from its built-in fuel gauge, the generator allows for easy and immediate gas level inspections.

As far as security is concerned, the generator can be used with a peace of mind, as it features an overload protection (circuit breaker) and an automatic low oil shut-off.

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.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the DuroStar DS4500DX also comes with some accessories: tool kit, funnel and propane hose are included.

Product Video

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 dual fuel generators of similar power (between 3000 and 4000 W).

  • A weight of 126 lbs makes the DuroStar DS4500DX one of the heavier dual fuel devices in the 3000-4000 rated wattage range. If you are mindful of weight, the A-iPower SUA4300iD is among the top contenders in this power range, with a dry weight of 54.8 pounds.
  • When comparing it to devices with a similar running wattage, this generator's lowest noise level of 69 dBA puts it alongside the noisier units. If you value reduced noise levels, the Westinghouse iGen4500DF could be worth considering. It's one of the quietest generators in its power range, rated at 52 dBA.
  • Compared to dual fuel devices of similar power, the DS4500DX stands out with one of the highest run times, lasting up to 25 hours at 25% load.
  • 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 one of the most fuel-efficient models of the aforementioned output range, as its estimated fuel consumption reaches just 0.16 GPH (gallon per hour) at 25% load.

Price comparison

As you can see from these interactive charts, when compared to other 3000-4000W dual fuel generators, the DuroStar DS4500DX is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
