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 a nutshell, the DuroStar DS11000X is a powerful portable generator mostly geared towards:

  • Homeowners who wish to power almost all appliances in their house under any circumstances
  • 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's engine, 457 cc OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 9000W and reaches a peak wattage of 11000W.

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

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

The DS11000X 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 if this DuroStar generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor, thanks to its L5-30R receptacle. Besides, due to the featured twist-lock L14-30R receptacle, the DS11000X is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

The dimensions of the DuroStar DS11000X, 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. This type of design is ideal for tough environments and heavy outdoor use.

While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 230 lbs. However, its challenging mobility is solved by its wheel kit and its folding handle, which will ease its displacement, once it is on the floor.

Features

Panel of the DuroStar DS11000X

The DS11000X's control panel

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

In addition to this info, a light indicator shows you if its oil levels are insufficient.

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

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

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).

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the DuroStar DS11000X also comes with some accessories: funnel and tool kit are included.

Emissions

The DuroStar DS11000X is EPA-approved and CARB-compliant. It can therefore be sold and purchased in all 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. In terms of weight, one of the champions in their power range is the Rainier R12000DF, standing at just 196 lbs.
  • Since the generator's noise is rated at 74 dBA, it has the roughly average expected noise for a device of similar power. If noise emissions are one of your priorities, you may be interested in the A-iPower SUA12000ED, one of the least noisy generators similarly powerful as this one, rated for 69 dBA.
  • The DS11000X's autonomy is somewhat low end compared to devices of its power range, as it reaches only around 8.8 hours at 50% load on a full tank. 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 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 DS11000X is on the average side of the price range.

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