Zoom on the DuroStar DS12000EH

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

  • Small homeowners in search of a full power backup solution
  • 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 DS12000EH in use

The DuroStar DS12000EH

The dual-fuel technology of the DuroStar DS12000EH allows for an output of 120/240V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 9,500W and a starting wattage of 12,000W. If propane-powered, it gives 8,750 rated watts and 10,500 starting watts.

The generator features a conventional pull-start mechanism and also a convenient and easy-to-use electric starter (battery included). It is rated for a noise of 74 dBA (just slightly more noisy than a vacuum cleaner).

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).

As the DS12000EH has a relatively high THD (<12%), it is not recommended to use it to power sensitive electronic devices.

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

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

Even if this DuroStar generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor, thanks to its L5-30R receptacle. 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 DuroStar DS12000EH has the following dimensions: L29 x W30 x H26 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 224 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 DS12000EH

The DS12000EH's control panel

The DS12000EH'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, the device’s light indicator will display if the oil level is too low.

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.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the DuroStar DS12000EH also comes with several accessories, including: battery charging cables, funnel, tool kit and propane hose. An official storage cover is also available, as a separate purchase.

Emissions

The DuroStar DS12000EH 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, which makes it suitable 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.
