Description

Zoom on the DuroStar DS11000DX

In a nutshell, the DuroStar DS11000DX is a powerful portable generator mostly geared towards:

  • 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 DS11000DX in use

The DuroStar DS11000DX

Thanks to its dual-fuel technology, the DuroStar DS11000DX delivers 120/240V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 9000W and a peak wattage of 11000W. When propane-powered, it has 8550 rated watts and 10450 peak watts.

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

The running time of the DS11000DX, with its 8.3 gallons fuel capacity, can reach around 8.8 hours at 50% load on a full tank of gasoline (fuel consumption around 0.94 GPH). With propane, it can reach around 3.6 hours (on a 20 lbs tank - propane consumption around 1.31 GPH).

The DS11000DX is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<12%).

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 though this DuroStar generator isn't quite RV Ready, its L5-30R receptacle allows an easy RV connection via an L5-30P to TT-30R adaptor. Besides, as it features a twist-lock L14-30R receptacle, the DS11000DX is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.

Portability

The dimensions of the DuroStar DS11000DX, which are L29 x W30 x H26 in, and its typical, open frame design provides stability and enables the generator to be raised above ground level. The featured design is ideal for the outdoors and all tough 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 230 pounds. 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

Panel of the DuroStar DS11000DX

The DS11000DX's control panel

To help you monitor the DS11000DX's status and activity, its control panel is equipped with a convenient meter showing you voltage, frequency and lifetime hours.

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 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 DS11000DX 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).

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the DuroStar DS11000DX also comes with several accessories, including: tool kit, funnel and propane hose.

Emissions

The DuroStar DS11000DX 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 DS11000DX versus other generators

The following charts are provided to give you an idea of how some of the key specs of the DuroStar DS11000DX compare to dual fuel generators of similar power (between 8500 and 9500 W).

  • A weight of 230 lbs makes the DuroStar DS11000DX one of the heavier dual fuel devices in the 8500-9500 rated wattage range. 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.
  • The generator can be considered average in its noise for its type and power category, as it is rated at 74 dBA. If you are concerned with noise, check out the A-iPower SUA12000ED, which is one of the least noisy generators in its power range, with a noise rating of 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 DS11000DX falls into the low end in comparison with other dual fuel devices of a comparable power output. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Westinghouse WGen9500DF, as it provides 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 rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 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 dual fuel generators, the DuroStar DS11000DX is on the expensive side of the price range.

While certainly not the cheapest of its kind, purchasing it would most likely also mean enjoying the reliability of a high-end product.
