Description

Zoom on the DuroStar DS11000DX

In summary, the DuroStar DS11000DX is a powerful portable generator especially useful for:

  • 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 following paragraphs, we shall explore the power characteristics, available outlets, portability, and any additional features of the device.

Power & Run Time

The DuroStar DS11000DX in use

The DuroStar DS11000DX

With its dual-fuel technology, the DuroStar DS11000DX delivers 120/240V, and offers power and flexibility. Running on gasoline, it boasts a running wattage of 9,000W and a peak wattage of 11,000W. When powered by propane, it delivers 8,550 running watts and 10,450 peak watts.

At a noise rating of 74 dBA (just slightly more noisy than a shower), this generator can be started via a classic hand-operated recoil starting mechanism, or a simple and elegant electric starter (battery included).

In terms of running time, the DS11000DX, equipped with a 8.3 gallons fuel tank, is capable of running continuously for up to 19 hours on a full gasoline tank (with fuel consumption estimated at around 0.44 gallons per hour). When utilizing propane, it provides up to 7 hours (on a 20 lbs tank - propane consumption around 0.67 GPH) of operation.

The powering of sensitive electronic devices with the DS11000DX is not recommended due to its relatively high THD (<12%).

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, with its twist-lock L14-30R receptacle, the DS11000DX is designed to be transfer switch ready, allowing easy connection to your breaker box for powering your home during a blackout.

Portability

With dimensions of L29 x W30 x H26 in, the standard open frame design of the DuroStar DS11000DX provides stability and easy maintenance access to components, as well as good air circulation. The device has been designed for tough environments and demanding outdoor use.

Though weighing 230 lbs, the generator remains classified as 'portable,' indicating its capability to be moved, though its weight could pose transport challenges. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit (⌀10") and its folding handle, once it is placed on the ground.

Features

Panel of the DuroStar DS11000DX

The DS11000DX's control panel

Included in the control panel of the DS11000DX are a convenient meter, providing voltage, frequency, and lifetime hours data, essential for monitoring its status and activity.

In addition to this info, when its oil levels are insufficient, you will be informed by the featured light indicator.

Equipped with a built-in fuel gauge, the generator facilitates swift gas level checks.

From a security point of view, the generator is equipped with an overload protection (circuit breaker) and an automatic low oil shut-off, giving you a peace of mind during use.

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.

Apart from the standard documentation and an owner's manual (opens in a new tab) to facilitate setup, the DuroStar DS11000DX features extra accessories: propane hose, funnel and tool kit.

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).

  • With a weight of 230 lbs, the DuroStar DS11000DX sits in the heaviest end of the spectrum among dual fuel generators rated from 8500 to 9500. If weight is an important consideration for you, the Westinghouse iGen11000DFc stands out as one of the top contenders in this power category, with a dry weight of 187.4 pounds.
  • When compared to other units producing a similar running wattage, this generator and its lowest emitted noise of 74 dBA stand out for being on the louder side. If noise level is one your key decisive factors, you may find the DuroMax XP11000iH appealing. It's rated at 61 dBA, making it one of the quietest generators in its power range.
  • At 25% load, the DS11000DX achieves one of the longer run times compared to dual fuel devices of similar power, sustaining operations for up to 19 hours. If extended autonomy is what matters most to you, the DuroMax XP10000DX could be an excellent choice, offering one of the longest run times among units in its power category, reaching up to 22 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. With an estimated fuel consumption of 0.44 GPH at a 25% load, this generator aligns with the average gasoline usage range of comparable products. 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 these interactive charts, when compared to other 8500-9500W dual fuel generators, the DuroStar DS11000DX 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.
