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 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, along with its emission compliance information.

Power & Run Time

The DuroMax XP11500EH in use

The DuroMax XP11500EH

The dual-fuel technology of the DuroMax XP11500EH allows for an output of 120/240V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 9,000W and a starting wattage of 11,500W. If propane-powered, it gives 8,550 rated watts and 10,925 starting 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 vacuum cleaner).

As for its running time, the XP11500EH, along with its 8.3 gallons fuel capacity, can run for up to 20 hours with a full tank filled with gasoline (fuel consumption around 0.42 GPH). If propane is used, it can operate for up to 7.5 hours (on a 20 lbs tank - propane consumption around 0.63 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 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

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, because the XP11500EH is equipped with a twist-lock L14-30R receptacle, it is transfer switch ready: it can power your home during a power outage, as it can be easily connected to your breaker box to power your household.

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. Still, once it is on the ground, its wheel kit (⌀10") and its folding handle can easily solve the issue of low mobility and allow for easy relocation of the device.

Features

Panel of the DuroMax XP11500EH

The XP11500EH's control panel

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

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

The fuel level of the generator can be determined quickly, easily, and conveniently with the help of its built-in fuel gauge.

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.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the DuroMax XP11500EH, the following accessories are also included: tool kit, propane hose and funnel.

Emissions

The DuroMax XP11500EH 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.

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).

  • A weight of 224 lbs makes the DuroMax XP11500EH one of the heavier dual fuel devices in the 8500-9500 rated wattage range. If weight is your top priority, one of the champions in this power category is the Rainier R12000DF, weighing just 196 pounds.
  • The generator can be considered average in its noise for its type and power category, as it is rated at 74 dBA. If you’d prefer a less noisy device, one of the most quiet devices, which share the same power range with this one, is the A-iPower SUA12000ED, whose lowest noise levels reach just 69 dBA.
  • Since the XP11500EH boasts with a run time of up to 20 hours at 25% load, it can be safely judged as a device of a higher run time than most dual fuel generators of a comparable output. 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.
  • While the run time is an important parameter, it is dependent on the fuel tank’s capacity and thus, doesn’t say much on its own unless we consider 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 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 this interactive chart, 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.
