Description

Zoom on the DuroStar DS11000DX

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

  • Homeowners who wish to power almost all appliances in their house under any circumstances
  • 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 DS11000DX in use

The DuroStar DS11000DX

With its dual-fuel technology, the powerful and versatile DuroStar DS11000DX provides an output of 120/240V. While gasoline-powered, it gives a running wattage of 9000W along with a peak wattage of 11000W. While propane-powered, it provides 8550 rated watts and 10450 starting watts.

The generator is rated for a noise of 74 dBA (just slightly more noisy than a dishwasher). Its starting mechanisms include a simple traditional pull-start mechanism and a convenient and easy-to-use electric starter (battery included).

As for its running time, the DS11000DX, along with its 8.3 gallons fuel capacity, can run for around 8.8 hours at 50% load with a full tank filled with gasoline (fuel consumption around 0.94 GPH). If propane is used, it can operate for around 3.6 hours (on a 20 lbs tank - propane consumption around 1.31 GPH).

As the DS11000DX 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 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

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, because the DS11000DX 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

With its dimensions of L29 x W30 x H26 in, the conventional, open frame design of the DuroStar DS11000DX offers stability and allows 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. Nevertheless, thanks to its wheel kit and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

Panel of the DuroStar DS11000DX

The DS11000DX's control panel

The control panel of the DS11000DX includes a convenient meter, which displays voltage, frequency and lifetime hours, helpful for the monitoring of its status and activity.

In addition to this info, a light indicator shows you if the oil level is too low.

The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a built-in fuel gauge.

Security-wise, this product benefits from an automatic low oil shut-off and an overload protection (circuit breaker), which gives you a complete peace of mind when using it.

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).

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the DuroStar DS11000DX also comes with some accessories: funnel, tool kit and propane hose are included.

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, which makes it suitable 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 generators of similar power (between 8500 and 9500 W).

  • As its weight is 230 pounds, the DuroStar DS11000DX falls in the expected weight range of the devices in the 8500-9500 rated wattage category. If you are concerned by weight, one of the champions in the above-mentioned power range is the Rainier R12000DF, with a dry weight of just 196 pounds.
  • 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.
  • As for its autonomy, the DS11000DX, with an autonomy of around 8.8 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.
  • 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. 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 are concerned with gasoline efficiency, having a fuel consumption of just 0.55 GPH, the Westinghouse WGen9500DF 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 DS11000DX is on the average side of the price range.

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