Zoom on the DuroStar DS12000EH

In a nutshell, the DuroStar DS12000EH is a powerful portable generator mostly geared towards:

  • Small homeowners in search of a full power backup solution
  • Professionals who want to ensure that a power failure will not prevent them from working

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 DS12000EH in use

The DuroStar DS12000EH

With its dual-fuel technology, the powerful and versatile DuroStar DS12000EH provides an output of 120/240V. While gasoline-powered, it gives a running wattage of 9500W along with a peak wattage of 12000W. While propane-powered, it provides 8750 rated watts and 10500 starting watts.

The generator is rated for a noise of 74 dBA (just slightly more noisy than a vacuum cleaner). Its starting mechanisms include a simple traditional pull-start mechanism and a convenient and easy-to-use electric starter (battery included).

As for its running time, the DS12000EH, along with its 8.3 gallons fuel capacity, can run for around 8 hours at 50% load with a full tank filled with gasoline (fuel consumption around 1.04 GPH). If propane is used, it can operate for around 4 hours (on a 20 lbs tank - propane consumption around 1.18 GPH).

The quite high THD (<12%) of the DS12000EH makes it unsuitable for powering sensitive electronic devices.

Outlets

The control panel includes the following 5 AC outlets:

Duplex 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle
120/240V 50A (14-50R) receptacle

Furthermore, it has 1 DC outlet: there's a 12V 8A output with which charging your batteries is made easy.

This DuroStar generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor. Besides, due to the featured twist-lock L14-30R receptacle, the DS12000EH is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

The dimensions of the DuroStar DS12000EH, which are L29 x W30 x H26 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.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 224 lbs make it incredibly difficult to manually lift and transport. 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 DS12000EH

The DS12000EH's control panel

The DS12000EH and its control panel include a handy voltmeter that allows you to easily monitor power output anytime. This feature comes handy when monitoring its status and activity.

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

The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

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.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the DuroStar DS12000EH also is packed along with the following accessories: tool kit, battery charging cables, funnel and propane hose. An official storage cover is also available, as a separate purchase.

Emissions

The DuroStar DS12000EH 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, so it is adequate for use in forested areas.

The DuroStar DS12000EH versus other generators

The following charts are provided to give you an idea of how some of the key specs of the DuroStar DS12000EH compare to dual fuel generators of similar power (between 9000 and 10000 W).

  • A weight of 224 lbs makes the DuroStar DS12000EH one of the heavier dual fuel devices in the 9000-10000 rated wattage range. If weight is your top priority, one of the champions in this power category is the Pulsar PG12000B, weighing just 205 pounds.
  • This generator has a somewhat average expected noise for its type and power range, rated at 74 dBA. If noise emissions are important to you, one of the least noisy generators of this power range is the A-iPower SUA12000ED with only 69 dBA.
  • As for its autonomy, the DS12000EH, with an autonomy of around 8 hours at a 50% load, is placed on the low end among the generators of its kind. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Westinghouse WGen9500DF, boasting with around 12 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. This generator is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 1.04 GPH at a 50% load. If fuel consumption is your top priority, we suggest to check out the Westinghouse WGen9500DF, which has a fuel consumption of only 0.55 GPH and thus, is one of the most efficient devices in our database.
According to our stats, the following comparison is pretty popular: DuroStar DS12000EH vs DuroMax XP12000EH.

Price comparison

As you can see from this interactive chart, when compared to other 9000-10000W dual fuel generators, the DuroStar DS12000EH is on the average side of the price range.

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