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

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

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.

Enjoying a noise rating of 74 dBA (just slightly more noisy than a dishwasher), this generator can be started thanks to a simple traditional pull-start mechanism, but also to a convenient and easy-to-use electric starter (battery included).

The DS12000EH, with a fuel capacity of 8.3 gallons, reaches a run time of around 8 hours at 50% load utilizing gasoline (fuel consumption around 1.04 GPH). Alternatively, it can reach a run time of around 4 hours (on a 20 lbs tank - propane consumption around 1.18 GPH) with propane.

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

It also sports 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 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 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 221 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

To help you monitor the DS12000EH's status and activity, its control panel is equipped with a handy voltmeter that allows you to easily monitor power output anytime.

In addition to this info, the device’s light indicator will display if the oil level is too low.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

From a security point of view, the generator is equipped with an automatic low oil shut-off and an overload protection (circuit breaker), giving you a peace of mind during use.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the DuroStar DS12000EH, the following accessories are also included: battery charging cables, funnel, propane hose and tool kit. 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, making it usable 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 far as its dry weight is concerned, the DuroStar DS12000EH weighs just 221 pounds and thus, it is one of the lighter 9000 to 10000 rated wattage generators. Regarding dry weight, one of the champions in the same power range is the Rainier R12000DF, with a dry weight of only 196 lbs.
  • As this generator can emit noise as low as 74 dBA, it finds itself in the average expected noise for this kind of power. 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.
  • The DS12000EH’s autonomy is somewhat low end compared to devices of its power range, as it reaches only around 8 hours at 50% load on a full tank. If autonomy is your priority, one of the devices of a similar power output with the highest run time is the Powerhorse 13000ES, reaching 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. This generator is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 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.
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 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.
