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 in need of safely powering high-intensity work or lighting equipment

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

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.

At a noise rating of 69 dBA (less noisy than background music), this generator can be started via a conventional pull-start mechanism, or a convenient and easy-to-use electric starter (battery included).

Regarding its running time, the DS5500EH, with a 4 gallons fuel capacity can operate for around 9 hours at 50% load with a full tank of gasoline (fuel consumption around 0.44 GPH). When using propane, it can run for 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 includes the following 3 AC outlets:

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

It also sports 1 DC outlet: there's a 12V 8A output allowing you to easily charge your batteries.

As the DS5500EH holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home during 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 122 lbs. Still, once it is on the ground, its wheel kit and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

Features

Panel of the DuroStar DS5500EH

The DS5500EH's control panel

The DS5500EH's control center features a convenient voltmeter, which provides an easy way to monitor power output anytime to aid you with the monitoring of its status and activity.

In addition to this info, a light indicator allows you to instantly see if its oil levels are insufficient.

Thanks to a built-in fuel gauge, the generator allows you to quickly, conveniently and easily check the gas level at a glance.

From a security standpoint, the product offers an overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to use it with a peace of mind.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the DuroStar DS5500EH also comes with some accessories: battery charging cables, propane hose, funnel and tool kit are included.

Emissions

The DuroStar DS5500EH 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 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).

  • As far as its dry weight is concerned, the DuroStar DS5500EH weighs just 122 pounds and thus, it is one of the lighter 4000 to 5000 rated wattage generators. If weight matters to you, one of the champions in this power range is the Powerhorse LC4500i with only 99 pounds.
  • Since the generator's noise is rated at 69 dBA, it has the roughly average expected noise for a device of similar power. 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 Powerhorse LC4500i, whose lowest noise levels reach just 57 dBA.
  • Regarding its autonomy, the autonomy of the DS5500EH, reaching around 9 hours at a 50% load, can be considered as low end, compared to other products of a roughly equal output. Concerning the run times, one of the several devices with a comparable output, offering the highest autonomy, is the Dewalt DXGN4500, which is able to run for around 15 hours.
  • 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. At an estimated fuel consumption of 0.44 GPH (gallon per hour) at 50% load, this generator is a rather fuel efficient one within its wattage category. If fuel consumption is your top priority, we suggest to check out the Pulsar PG5250B, which has a fuel consumption of only 0.33 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 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.
