Zoom on the DuroMax XP15000HX

In a few words, the DuroMax XP15000HX is a powerful portable generator perfectly suited for 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.

Power & Run Time

The DuroMax XP15000HX in use

The DuroMax XP15000HX

Featuring dual-fuel technology, the DuroMax XP15000HX provides 120/240V, as well as versatility and power. Running on gasoline, it delivers a running wattage of 12,000W and a peak wattage of 15,000W. Alternatively, when fueled by propane, it offers 11,400 running watts and 14,250 peak watts.

DuroMax’s Auto Fuel Selection technology automatically selects the fuel source (LPG or gasoline) depending on availability and prioritizes LPG. Thus, if a propane tank with enough LPG is connected, the generator will automatically use LPG. If no propane tank is connected, or if there is not enough LPG remaining in the tank, the generator will use gasoline.

Enjoying a noise rating of 78 dBA (less noisy than a shower), this generator offers the versatility of starting with either a conventional pull-start mechanism or a convenient and efficient electric starter (battery included). Moreover, the XP15000HX boasts remote starting functionality, adding another layer of convenience (key fob included).

With a fuel capacity of 13.2 gallons, the XP15000HX can operate for around 12 hours at 50% load using gasoline (fuel consumption around 1.1 GPH), or for around 2.8 hours (on a 20 lbs tank - propane consumption around 1.68 GPH) using propane.

The quite high THD (<12%) of the XP15000HX makes it unsuitable for powering sensitive electronic devices.


The control panel features the following 13 AC outlets:

Five Duplexes 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 XP15000HX is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.


With dimensions of L36 x W33.2 x H32 in, the traditional open frame design of the DuroMax XP15000HX ensures stability while allowing easy maintenance access to components and promoting effective air cooling. The generator is designed for ideal use outdoors and in rough environments.

Despite its weight of 345 lbs, the generator is considered 'portable,' signifying its capability to be moved, albeit its heaviness may hinder easy transport. Nonetheless, the limited maneuverability is compensated for by utilizing its wheel kit (⌀13") and its folding handle, which facilitates shifting once the generator is set on the ground.

The XP15000HX's control panel

Enhancing monitoring capabilities, the XP15000HX features a digital data center within its control panel, furnishing essential details on the power output, voltage, lifetime run hours, fuel level and frequency for tracking activity and status.

In addition to this info, the device’s light indicator will display if the oil level is too low.

In terms of security, the generator features an overload protection (circuit breaker) and an automatic low oil shut-off, ensuring peace of mind during its use.

The XP15000HX also benefits from DuroMax’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.

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the DuroMax XP15000HX also is packed along with the following accessories: funnel, propane hose, key fob and tool kit.

The DuroMax XP15000HX versus other generators

The following charts are provided to give you an idea of how some of the key specs of the DuroMax XP15000HX compare to dual fuel generators of similar power (between 10000 and 14000 W).

  • Weighing 345 lbs, the DuroMax XP15000HX is one of the heavier dual fuel generators within the 10000-14000 rated wattage bracket. If weight is a key factor for your needs, the Pulsar PG13000BRCO is noteworthy for being one of the top contenders in this power range, with a dry weight of 231 pounds.
  • If compared to generators capable of producing a similar running wattage, this generator with a lowest emitted noise of 78 dBA can be considered somewhat noisy. If noise emissions are one of your priorities, you may want to take a look at the DuroMax XP16000iH. It's one of the quietest options among generators of similar power, rated at 67 dBA.
  • Since the XP15000HX boasts with a run time of around 12 hours at 50% load, it can be safely judged as one of the dual fuel devices with the highest run time among those of a comparable output.
  • Though run time is a significant parameter, it's closely tied to the generator's fuel tank size. To get a comprehensive understanding, fuel efficiency must also be taken into account. This generator has an average fuel consumption among comparably powerful devices, as it reaches 1.1 GPH (gallon per hour) at a 50% load. If fuel consumption is your top priority, we suggest to check out the Westinghouse WGen12000DF, which has a fuel consumption of only 0.95 GPH and thus, is one of the most efficient devices in our database.

Price comparison

As you can see from these interactive charts, when compared to other 10000-14000W dual fuel generators, the DuroMax XP15000HX is on the cheap side of the price range.

It can therefore be a really good buy if you're looking to acquire a budget generator.
