Description

Powered by a 457cc OHV engine, this generator is perfect for home power backup and will run your household essentials such as lights, appliances, and central AC system with ease during a blackout, storm, or emergency event.

Zoom on the DuroStar DS11000X

In summary, the DuroStar DS11000X is a powerful portable generator especially useful for:

  • 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 following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device, along with its emission compliance information.

Power & Run Time

The DuroStar DS11000X in use

The DuroStar DS11000X

The DuroStar DS11000X is powered by a 457 cc OHV 4-stroke engine. It delivers 120/240V, runs on gasoline and offers a running wattage of 9,000W as well as a peak wattage of 11,000W.

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).

With a full tank, the DS11000X can operate for up to 19 hours (fuel consumption around 0.44 GPH), thanks to its fuel capacity of 8.3 gallons.

Since the DS11000X has a somewhat high THD (<12%), it is advisable to not use it for the powering of sensitive electronic devices.

Outlets

The control panel features the following 7 AC outlets:

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

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, because the DS11000X is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.

Portability

The design of the DuroStar DS11000X is a typical, open frame, with the dimensions of L29 x W30 x H26 in, offering support and stability and enabling the possibility of raising it above ground level. The design is ideal for rough 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 230 lbs. However, this lack of maneuverability is compensated by its wheel kit (⌀10") and its folding handle, with which you can conveniently shift it, once it's on the ground.

Features

The DS11000X's control panel

The DS11000X and its control panel include a convenient meter, which displays voltage, frequency and lifetime hours. This feature comes handy when monitoring 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.

The DS11000X also benefits from DuroStar’s CO Alert carbon monoxide shutdown. If CO levels become unsafe or rapidly increase, the generator will automatically shut down, an indicator will light red, and the engine will not restart for 5 minutes.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the DuroStar DS11000X also is packed along with the following accessories: funnel and tool kit.

Emissions

The DuroStar DS11000X 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, which makes it suitable for use in forested areas.

Product Video

The DuroStar DS11000X versus other generators

The following charts are provided to give you an idea of how some of the key specs of the DuroStar DS11000X compare to generators of similar power (between 8500 and 9500 W).

  • Since the generator weighs in at a dry weight of 230 lbs, the DuroStar DS11000X belongs in the expected weight range for devices which can produce between 8500 and 9500 rated watts. If weight is your top priority, one of the champions in this power category is the Rainier R12000DF, weighing just 196 pounds.
  • The generator can be considered average in its noise for its power category, as it is rated at 74 dBA. If noise emissions are important to you, one of the least noisy generators of this power range is the Genmax GM10500iETC with only 64 dBA.
  • The DS11000X provides a higher run time than similarly powerful devices, reaching up to 19 hours at 25% load. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the DuroMax XP10000DX, as it provides up to 22 hours.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider fuel consumption as well. At an estimated fuel consumption of 0.44 GPH (gallon per hour) at 25% load, this generator is a rather fuel efficient one within its wattage category. If you are concerned with gasoline efficiency, having a fuel consumption of just 0.38 GPH, the DuroMax XP10000DX is a device you could look out for.

Price comparison

As you can see from this interactive chart, when compared to other 8500-9500W generators, the DuroStar DS11000X 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.
