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

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 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.

With a noise rating of 74 dBA (just slightly more noisy than a shower), the generator features a simple traditional pull-start mechanism, but also a convenient and easy-to-use electric starter (battery included).

With a full tank, the DS11000X can operate for around 8.8 hours at 50% load (fuel consumption around 0.94 GPH), thanks to its fuel capacity of 8.3 gallons.

As the DS11000X has a relatively high THD (<12%), it is not recommended to use it to power 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

While this DuroStar generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor. 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 DuroStar DS11000X 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 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 230 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

The DS11000X's control panel

The DS11000X's control center features a convenient meter, which displays voltage, frequency and lifetime hours to aid you with the monitoring of its status and activity.

In addition to this info, the device’s light indicator will display if its oil levels are insufficient.

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 overload protection (circuit breaker) and an automatic low oil shut-off, letting you 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. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the DuroStar DS11000X, the following accessories are also included: tool kit and funnel.

Emissions

The DuroStar DS11000X 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, so it is adequate 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).

  • Having a dry weight of 230 lbs, the DuroStar DS11000X belongs in the expected weight range for generators which produce 8500 to 9500 rated watts. If you are concerned by weight, one of the champions in the above-mentioned power range is the Pulsar PG12000B, with a dry weight of just 205 pounds.
  • Because this generator emits noise as low as 74 dBA, it can be considered to have a pretty average expected noise rating for a device of its power. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the A-iPower SUA12000ED, whose lowest noise levels reach just 69 dBA.
  • As far as autonomy is concerned, providing around 8.8 hours of runtime with a full tank at a 50% load, the DS11000X falls into the low end in comparison with other devices of a comparable power 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 Westinghouse WGen9500DF, with around 12 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 somewhat less fuel efficient than devices of comparable output: its estimated fuel consumption reaches 0.94 GPH at a 50% load. If you wish to further improve in the area of fuel efficiency, the Westinghouse WGen9500DF, which boasts with a gas consumption of only 0.55 GPH, may be the right generator for you.

Price comparison

As you can see from this interactive chart, when compared to other 8500-9500W generators, the DuroStar DS11000X is on the average side of the price range.

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