Description

Be ready for anything with the DuroMax XP11500EH generator. Equipped to run on either gasoline or liquid propane, this dual fuel unit can perform anywhere that portable power is needed. (source: DuroMax (opens in a new tab))

Zoom on the DuroMax XP11500EH

In a nutshell, the DuroMax XP11500EH is a powerful portable generator mostly geared towards:

  • 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

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 DuroMax XP11500EH in use

The DuroMax XP11500EH

Thanks to its dual-fuel technology, the DuroMax XP11500EH delivers 120/240V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 9000W and a peak wattage of 11500W. When propane-powered, it has 8550 rated watts and 10925 peak watts.

At a noise rating of 72 dBA (just slightly more noisy than a vacuum cleaner), this generator can be started via a conventional pull-start mechanism, or a simple and elegant electric starter (battery included).

As for its running time, the XP11500EH, along with its 8.3 gallons fuel capacity, can run for around 8 hours at 50% load with a full tank filled with gasoline (fuel consumption around 1.04 GPH). If propane is used, it can operate for around 3 hours (on a 20 lbs tank - propane consumption around 1.57 GPH).

Since the XP11500EH has a somewhat high THD (<12%), it is advisable to not use it for the powering of sensitive electronic devices.

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

While this DuroMax generator is not RV Ready, its L5-30R receptacle can be used for a simple RV connection with an L5-30P to TT-30R adaptor. Besides, due to the featured twist-lock L14-30R receptacle, the XP11500EH is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.

Portability

With its dimensions of L29 x W30 x H26 in, the conventional, open frame design of the DuroMax XP11500EH offers stability and allows the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

As the generator's weight is 224 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). 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

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

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

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 product offers an overload protection (circuit breaker) and an automatic low oil shut-off, allowing you to use it with a peace of mind.

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the DuroMax XP11500EH also comes with some accessories: tool kit, funnel and propane hose are included.

Emissions

The DuroMax XP11500EH is EPA-approved and CARB-compliant. Therefore, its sale and purchase are permitted in all of the 50 states, including California.

Moreover, it features a spark arrestor, making it usable in forested areas.

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 generators of similar power (between 8500 and 9500 W).

  • At a weight of 224 pounds, the DuroMax XP11500EH places in the expected weight range of the generators in the 8500-9500 rated wattage range. 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.
  • With a lowest possible noise of 72 dBA, this generator places itself amongst the more quiet of the products delivering similar power. For those who are looking for a less noisy device, we suggest the A-iPower SUA12000ED. With just 69 dBA, it is one of the most quiet devices in this power range.
  • As for its autonomy, the XP11500EH, with an autonomy of around 8 hours at a 50% load, is placed on the low end among the generators of its kind. If you consider autonomy on a single full tank as one of the deciding factors, one of the generators in the same power range that offers the highest run time is the Westinghouse WGen9500DF, with around 12 hours.
  • The run time is important, but also hugely depends on the capacity of the fuel tank and doesn't mean much if we don't talk about fuel consumption as well. Compared to its peers, this generator is not exactly fuel efficient, compared to similarly powerful devices, with an estimated fuel consumption of 1.04 GPH at a 50% load. If fuel consumption is your top priority, we suggest to check out the Westinghouse WGen9500DF, which has a fuel consumption of only 0.55 GPH and thus, is one of the most efficient devices in our database.

Price comparison

As you can see from this interactive chart, when compared to other 8500-9500W 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.
