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.

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 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, including its emission compliance information.

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 9,000W and a peak wattage of 11,500W. When propane-powered, it has 8,550 rated watts and 10,925 peak watts.

The generator features a conventional pull-start mechanism and also a convenient and easy-to-use electric starter (battery included). It is rated for a noise of 74 dBA (just slightly more noisy than a dishwasher).

With a fuel capacity of 8.3 gallons, the XP11500EH can operate for up to 20 hours using gasoline (fuel consumption around 0.42 GPH), or for up to 7.5 hours (on a 20 lbs tank - propane consumption around 0.63 GPH) using propane.

As the XP11500EH has a relatively high THD (<12%), it is not recommended to use it to power sensitive electronic devices.

Outlets

The control panel features the following 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

This DuroMax generator features an L5-30R receptacle, enabling an easy RV connection via an L5-30P to TT-30R adaptor. However, it is still not quite RV ready. Besides, as the XP11500EH holds a twist-lock L14-30R receptacle, it is transfer switch ready: you'll easily be able to connect it to your breaker box to power your home 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.

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, this lack of maneuverability is compensated by its wheel kit (⌀10") and its folding handle, with which you can conveniently shift it, once it's on the ground.

Features

Panel of the DuroMax XP11500EH

The XP11500EH's control panel

To help you monitor the XP11500EH'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 shows you if its oil levels are insufficient.

The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the DuroMax XP11500EH's package also includes these accessories: tool kit, propane hose and funnel.

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 and thus, may be used 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 dual fuel generators of similar power (between 8500 and 9500 W).

  • Considering its dry weight of 224 pounds, the DuroMax XP11500EH is one of the heavier dual fuel generators producing between 8500 and 9500 running watts. If you are concerned by weight, one of the champions in the above-mentioned power range is the Westinghouse iGen11000DFc, with a dry weight of just 187.4 pounds.
  • Since the generator's noise is rated at 74 dBA, it has the roughly average expected noise for a device of similar type and power. If noise emissions are important to you, one of the least noisy generators of this power range is the Westinghouse iGen11000DFc with only 64 dBA.
  • With a run time of up to 20 hours at 25% load, the XP11500EH has one of the higher run times, compared to its similarly powerful peers. 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 DuroMax XP10000DX, with up to 22 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. 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 you wish to acquire one of the most gasoline efficient products of this power range, the DuroMax XP10000DX, with a fuel consumption of 0.38 GPH could be in your good books.

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 expensive side of the price range.

While certainly not the cheapest of its kind, purchasing it would most likely also mean enjoying the reliability of a high-end product.
