Zoom on the DuroMax XP11500EH

In a few words, the DuroMax XP11500EH is a powerful portable generator perfectly suited for:

  • Small homeowners in search of a full power backup solution
  • 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.

Power & Run Time

The DuroMax XP11500EH in use

The DuroMax XP11500EH

Featuring dual-fuel technology, the DuroMax XP11500EH provides 120/240V, and offers both power and versatility. Running on gasoline, it delivers a running wattage of 9,000W and a starting wattage of 11,500W. When propane-powered, it offers 8,550 running watts and 10,925 starting watts.

The generator is rated for a noise of 74 dBA (just slightly more noisy than a dishwasher). Its starting mechanisms include a traditional recoil pull-start mechanism and a hassle-free and practical electric starter (battery included).

In terms of its run time capability, the XP11500EH, furnished with a 8.3 gallons fuel tank, can maintain operations for up to 20 hours on a full tank of gasoline (with fuel consumption averaging 0.42 gallons per hour). It also provides up to 7.5 hours (on a 20 lbs tank - propane consumption around 0.63 GPH) of operation with propane.

The XP11500EH is unsuitable for the powering of sensitive electronic devices due to its relatively high THD (<12%).

Outlets

The control panel provides the upcoming 5 AC outlets:

Duplex 120V 20A (5-20R) GFCI
120V 30A (L5-30R) receptacle
120/240V 30A (L14-30R) receptacle
120/240V 50A (14-50R) receptacle

Despite not having the 'RV Ready' status, this DuroMax generator provides the benefit of convenient RV compatibility through its L5-30R receptacle, enabling you to easily power your RV using an L5-30P to TT-30R adaptor. Besides, with its twist-lock L14-30R receptacle, the XP11500EH is configured to be transfer switch ready, allowing straightforward connection to your breaker box to supply backup power to your home during outages.

Portability

With a size of L29 x W30 x H26 in, the DuroMax XP11500EH features an open frame design, providing stability and simplified maintenance access to components, enhancing air circulation. The generator is designed for ideal use outdoors and in rough environments.

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 224 lbs. However, the limited maneuverability is remedied with its wheel kit (⌀10") and its folding handle, facilitating convenient shifting once the generator is positioned on the ground.

Features

The XP11500EH's control panel

The XP11500EH and its control panel include a convenient meter, displaying voltage, frequency, and lifetime hours information. This feature comes handy when monitoring its status and activity.

In addition to this info, a light indicator serves to show you when 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.

From a security standpoint, the generator is furnished with an automatic low oil shut-off and an overload protection (circuit breaker), ensuring peace of mind during operation.

With the basic documentation and an owner's manual (opens in a new tab), letting you start the generator quickly, the DuroMax XP11500EH also comes with several accessories, including: tool kit, funnel and propane hose.

The DuroMax XP11500EH versus other generators

The following charts are provided to give you an idea of how some of the key specs of the DuroMax XP11500EH compare to dual fuel generators of similar power (between 8500 and 9500 W).

  • With a weight of 224 lbs, the DuroMax XP11500EH is notably on the heavier side among dual fuel generators in the 8500-9500 rated wattage range. If you are mindful of weight, the Westinghouse iGen11000DFc is among the top contenders in this power range, 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 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.
  • With up to 20 hours of runtime at 25% load, the XP11500EH provides a higher run time when compared to similarly powerful dual fuel products. For those prioritizing autonomy, the DuroMax XP10000DX could be considered, as it offers one of the longest run times among generators with similar power output, reaching up to 22 hours.
  • Run time is crucial, but it heavily relies on the fuel tank's capacity. Thus, considering fuel efficiency alongside is essential. This generator can be considered as fuel-efficient, due to its low estimated fuel consumption of only 0.42 GPH (gallon per hour) at 25% load, within the aforementioned wattage range. If gasoline efficiency is at the top of your list, you may want to have a look at the DuroMax XP10000DX, which has great fuel efficiency, with a gas consumption of only 0.38 gallons per hour.

Price comparison

As you can see from these interactive charts, when compared to other 8500-9500W dual fuel generators, the DuroMax XP11500EH is on the average side of the price range.

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