Description

Powered by a 212cc DuroStar engine, this Dual Fuel generator is excellent for camping, RVs, power on the jobsite, and will run various household essentials such as lights and appliances when the power goes out.

Zoom on the DuroStar DS4500DX

In summary, the DuroStar DS4500DX is a portable generator especially useful for:

  • RV travellers wishing to enhance their freedom and nomad lifestyle
  • People occasionally participating in sporting competitions, open-air performances and outdoor festivals
  • DIYers who wish to improve their efficiency with tools
  • Homeowners who want to be able to use the most necessary devices in their household, even during a blackout
  • Professionals who want to ensure that a power failure will not prevent them from working

In the following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with 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.

At a noise rating of 69 dBA (less noisy than a normal conversation), this generator can be started via a conventional pull-start mechanism, or a simple and elegant electric starter (battery included).

The DS4500DX, with a fuel capacity of 4 gallons, reaches a run time of around 10.4 hours at 50% load utilizing gasoline (fuel consumption around 0.38 GPH). Alternatively, it can reach a run time of around 8.9 hours (on a 20 lbs tank - propane consumption around 0.53 GPH) with propane.

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 includes the following 3 AC outlets:

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

As it features a twist-lock L14-30R receptacle, the DS4500DX is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.

Portability

The DuroStar DS4500DX has the following dimensions: L25 x W23 x H22 in. In combination with its conventional, open frame design, they provide support and allow the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 126 lbs. However, its challenging mobility is solved by its wheel kit and its folding handle, which will ease its displacement, once it is on the floor.

Features

Panel of the DuroStar DS4500DX

The DS4500DX's control panel

The DS4500DX's status and activity may be monitored conveniently via the control panel, as it features 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.

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. 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: tool kit, propane hose and funnel.

Emissions

The DuroStar DS4500DX 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, 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 dual fuel generators of similar power (between 3000 and 4000 W).

  • Considering its dry weight of 126 pounds, the DuroStar DS4500DX is one of the heavier dual fuel generators producing between 3000 and 4000 running watts. Regarding dry weight, one of the champions in the same power range is the Genmax GM3500iAED, with a dry weight of only 56.2 lbs.
  • When compared to devices able to produce a similar running wattage, this generator and its lowest emitted noise of 69 dBA is on the noisier side. If you are concerned with noise, check out the Westinghouse iGen4500DF, which is one of the least noisy generators in its power range, with a noise rating of just 52 dBA.
  • Given that the DS4500DX reaches an autonomy of around 10.4 hours with a full tank and at 50% load, it is placed within the average autonomy range of similarly powerful dual fuel generators. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Westinghouse iGen4500DF, as it provides around 15 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 0.38 GPH at a 50% load. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen4500DF, which has a fuel consumption of only 0.23 GPH and thus, is one of the most efficient devices in our database.

Price comparison

As you can see from this interactive chart, 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.
