Description

The DuroStar 5,500 Watt Dual-Fuel Generator is the most powerful generator in its class. Powered by either gasoline or propane, the dual-fuel capability coupled with an available 5.500 peak watts in a small footprint allows this generator to be used anywhere for anything!

Zoom on the DuroStar DS5500EH

In a nutshell, the DuroStar DS5500EH is a portable generator mostly geared towards:

  • RV travellers looking for even more independence
  • People occasionally participating in outdoor fairs, festivals or events
  • 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 DS5500EH in use

The DuroStar DS5500EH

With its dual-fuel technology, the powerful and versatile DuroStar DS5500EH provides an output of 120/240V. While gasoline-powered, it gives a running wattage of 4500W along with a peak wattage of 5500W. While propane-powered, it provides 4275 rated watts and 5225 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).

The running time of the DS5500EH, with its 4 gallons fuel capacity, can reach around 9 hours at 50% load on a full tank of gasoline (fuel consumption around 0.44 GPH). With propane, it can reach around 8 hours (on a 20 lbs tank - propane consumption around 0.59 GPH).

The powering of sensitive electronic devices with the DS5500EH is not recommended due to its relatively high THD (<12%).

Outlets

The control panel features the following 3 AC outlets:

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

Additionally, it features 1 DC outlet: there's a 12V 8A output with which you may charge your batteries with ease.

Since the DS5500EH bears a twist-lock L14-30R receptacle, it is transfer switch ready: it is easily connectible to a breaker box and can power your home in case of a power outage.

Portability

The design of the DuroStar DS5500EH is a typical, open frame, with the dimensions of L25 x W22 x H22 in, offering support and stability and enabling the possibility of raising it above ground level. The device has been designed for tough environments and demanding outdoor use.

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 127 lbs. 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

Panel of the DuroStar DS5500EH

The DS5500EH's control panel

The DS5500EH's status and activity may be monitored conveniently via the control panel, as it features a convenient voltmeter, which provides an easy way to monitor power output anytime.

In addition to this info, a light indicator allows you to instantly see if the oil level is too low.

The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a 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.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the DuroStar DS5500EH, the following accessories are also included: battery charging cables, propane hose, funnel and tool kit.

Emissions

The DuroStar DS5500EH 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 thus, may be used in forested areas.

The DuroStar DS5500EH versus other generators

The following charts are provided to give you an idea of how some of the key specs of the DuroStar DS5500EH compare to generators of similar power (between 4000 and 5000 W).

  • Weight-wise, the DuroStar DS5500EH has only 127 lbs, which renders it one of the lighter generators which produce 4000 to 5000 rated watts. Regarding dry weight, one of the champions in the same power range is the Pulsar PG5250, with a dry weight of only 99.5 lbs.
  • As this generator can emit noise as low as 69 dBA, it finds itself in the average expected noise for this kind of power. For those who are looking for a less noisy device, we suggest the Yamaha EF4500iSE. With just 58 dBA, it is one of the most quiet devices in this power range.
  • As for its autonomy, the DS5500EH, with an autonomy of around 9 hours at a 50% load, is placed on the low end among the generators of its kind. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Dewalt DXGN4500, with around 15 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. This generator, with an estimated fuel consumption of just 0.44 GPH (gallon per hour) at 50% load, is one of the more fuel efficient generators, for the previously mentioned wattage range. If you wish to acquire one of the most gasoline efficient products of this power range, the Pulsar PG5250B, with a fuel consumption of 0.33 GPH could be in your good books.

Price comparison

As you can see from this interactive chart, when compared to other 4000-5000W generators, the DuroStar DS5500EH is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.
