Zoom on the DuroStar DS12000EH

In summary, the DuroStar DS12000EH is a powerful portable generator especially useful for:

  • Prudent homeowners who want a backup power source in case of a power outage
  • Professionals in need of safely powering high-intensity work or lighting equipment

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 conventional 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).

Outlets

The control panel provides the upcoming 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 features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready. 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 design of the DuroStar DS12000EH is a typical, open frame, with the dimensions of L30 x W22 x H26 in, offering support and stability and enabling the possibility of raising it above ground level. The generator is designed for ideal use outdoors and in rough environments.

Even though this device may be technically portable (as in movable), manipulation and transportation without special equipment can be a challenge, as it weighs 221 pounds. 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 control panel of the DS12000EH includes a handy voltmeter that allows you to easily monitor power output anytime, helpful for the monitoring of its status and activity.

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 for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the DuroStar DS12000EH's package also includes these accessories: battery charging cables, tool kit, funnel and propane hose.

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 generators of similar power (between 9000 and 10000 W).

  • As for its weight, the DuroStar DS12000EH weighs only 221 pounds, making it one of the lighter generators in the 9000-10000 rated wattage category. In terms of weight, one of the champions in their power range is the Rainier R12000DF, standing at just 196 lbs.
  • The generator can be considered average in its noise for its power category, as it is rated at 74 dBA. If noise emissions are one of your priorities, you may be interested in the A-iPower SUA12000ED, one of the least noisy generators similarly powerful as this one, rated for 69 dBA.
  • Regarding its autonomy, the autonomy of the DS12000EH, reaching around 8 hours at a 50% load, can be considered as low end, compared to other products of a roughly equal output. 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 Powerhorse 13000ES, with around 15 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This generator is somewhat less fuel efficient than devices of comparable output: its estimated fuel consumption reaches 1.04 GPH at a 50% load. If fuel consumption is your top priority, we suggest to check out the Rainier R12000DF, which has a fuel consumption of only 0.55 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 9000-10000W 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.
