Description

Zoom on the DuroStar DS11000DX

In short, the DuroStar DS11000DX is a powerful portable generator adequately designed 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

Over the following sections, you'll uncover its power characteristics, the selection of outlets it offers, its overall portability, and the supplementary features it includes.

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 9,000W along with a peak wattage of 11,000W. While propane-powered, it provides 8,550 rated watts and 10,450 starting watts.

Featuring a noise rating of 74 dBA (just slightly more noisy than a dishwasher), the generator is equipped with both a conventional pull-start mechanism and a user-friendly and hassle-free electric starter (battery included) for starting.

With a fuel capacity of 8.3 gallons, the DS11000DX can operate for up to 19 hours using gasoline (fuel consumption around 0.44 GPH), or for up to 7 hours (on a 20 lbs tank - propane consumption around 0.67 GPH) using propane.

Given the DS11000DX's relatively high Total Harmonic Distortion (THD) of less than 12%, it is advisable to avoid using it to power sensitive electronic devices.

Outlets

The control panel includes 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 not classified as 'RV Ready,' this DuroStar generator can still provides the advantage of RV connection via its L5-30R receptacle, ensuring power supply to your RV with an L5-30P to TT-30R adaptor. Besides, thanks to its twist-lock L14-30R receptacle, the DS11000DX is transfer switch ready, facilitating easy hookup to your breaker box to provide backup power for your home during blackouts.

Portability

At L29 x W30 x H26 in, the DuroStar DS11000DX boasts a traditional open frame structure, ensuring stability and allowing for convenient maintenance access to components, promoting air circulation. The device has been designed for tough environments and demanding outdoor use.

Since the generator weighs 230 lbs, it will be incredibly difficult to manually lift it and transport it, even though it is technically considered to 'be portable' (in the sense that it is movable). Still, once it is on the ground, its wheel kit (⌀10") and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

Features

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, a light indicator allows you to instantly see if its oil levels are insufficient.

Thanks to its built-in fuel gauge, the generator allows you to quickly, conveniently, and easily check the gas level at a glance.

Regarding security, the generator comes with an overload protection (circuit breaker) and an automatic low oil shut-off, providing peace of mind during operation.

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.

Beyond the standard documentation and an owner's manual (opens in a new tab) to assist with setup, the DuroStar DS11000DX ships with supplementary accessories: propane hose, tool kit and funnel.

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).

  • At a dry weight of 230 pounds, the DuroStar DS11000DX is one of the heaviest dual fuel devices which can produce between 8500 and 9500 running watts. if you wish to prioritize weight, the Westinghouse iGen11000DFc is one of the top contenders in its power category, weighing only 187.4 pounds.
  • When comparing it to devices with a similar running wattage, this generator's lowest noise level of 74 dBA puts it alongside the noisier units. If you'd like a less noisy alternative, the DuroMax XP11000iH is a strong contender. It boasts a noise rating of 61 dBA, placing it among the quietest generators in its power category.
  • As for its runtime, the DS11000DX runs for around 9 hours at a 50% load, placing it towards the low end among comparable dual fuel products. If prolonged run time is essential to your needs, you could consider the Westinghouse iGen11000DFc, which offers one of the highest autonomy among devices with similar power output, lasting around 12 hours.
  • While run time is vital, it hinges on the fuel capacity. To grasp the full picture, we must also factor in fuel efficiency. This generator doesn't excel in fuel efficiency when compared to others of its kind: it consumes approximately 0.92 GPH at a 50% load. To prioritize fuel savings, we advise considering the Westinghouse iGen11000DFc, which stands out for its gasoline efficiency, consuming just 0.66 gallons per hour.

Price comparison

As you can see from these interactive charts, when compared to other 8500-9500W dual fuel 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.
