Description

The XP12000HX is the BEAST of the HX Series with 12,000-watts of POWER. This unit provides the power normally found in stationary home standby generators but in a more affordable, portable package! With a 457cc OHV DuroMax Engine, this workhorse is PERFECT for HOME BACK-UP.

Zoom on the DuroMax XP12000HX

To sum up, the DuroMax XP12000HX is a powerful portable generator tailored for:

  • Homeowners who wish to power almost all appliances in their house under any circumstances
  • Professionals who want to ensure that a power failure will not prevent them from working

In the forthcoming sections, you'll delve into its power characteristics, the various outlets it offers, its overall portability, and the additional features it boasts.

Power & Run Time

The DuroMax XP12000HX in use

The DuroMax XP12000HX

Thanks to its dual-fuel technology, the DuroMax XP12000HX provides a 120/240V output and offers both versatility and power. When utilizing gasoline, it delivers a running wattage of 9,500W and a starting wattage of 12,000W. Alternatively, when operating on propane, it provides 9,025 running watts and 11,400 starting watts.

Enjoying a noise rating of 74 dBA (just slightly more noisy than a shower), this generator can be started thanks to a manual recoil starter system, but also to an easy-to-use and reliable electric starter (battery included).

With a fuel capacity of 8.3 gallons, the XP12000HX can operate for up to 19 hours using gasoline (fuel consumption around 0.92 GPH), or for up to 7 hours (on a 20 lbs tank - propane consumption around 0.67 GPH) using propane.

The powering of sensitive electronic devices with the XP12000HX is not recommended due to its relatively high THD (<12%).

Outlets

The control panel provides the upcoming 7 AC outlets:

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

While not classified as 'RV Ready,' this DuroMax generator can still provides the advantage of RV connection via its L5-30R receptacle, ensuring power supply to your RV with an L5-30P to TT-30R adaptor. Besides, because the XP12000HX 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

At L29 x W30 x H26 in, the standard open frame design of the DuroMax XP12000HX delivers stability alongside easy maintenance access to components and good air cooling. The device has been designed for tough environments and demanding outdoor use.

With a weight of 230 lbs, the generator is still labeled as 'portable,' denoting its ability to be moved, although its heaviness might restrict easy portability. Nevertheless, thanks to its wheel kit (⌀10") and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.

Features

The XP12000HX's control panel

The XP12000HX's control center features a convenient meter, providing voltage, frequency, and lifetime hours data to aid you with the monitoring of its status and activity.

In addition to this info, when its oil levels are insufficient, you will be informed by the featured light indicator.

The inclusion of a built-in fuel gauge in the generator streamlines gas level checks for quick and convenient assessments.

As far as security is concerned, the generator can be used with a peace of mind, as it features an automatic low oil shut-off and an overload protection (circuit breaker).

The XP12000HX 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.

While the standard documentation and an owner's manual (opens in a new tab), helpful for starting the device promptly, come with the DuroMax XP12000HX, the following accessories are also included: funnel, propane hose and tool kit.

The DuroMax XP12000HX versus other generators

The following charts are provided to give you an idea of how some of the key specs of the DuroMax XP12000HX compare to dual fuel generators of similar power (between 9000 and 10000 W).

  • A weight of 230 lbs makes the DuroMax XP12000HX one of the heaviest dual fuel devices in the 9000-10000 rated wattage range. In terms of weight, one of the champions in their power range is the Westinghouse iGen11000DFc, standing at just 187.4 lbs.
  • 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 noise is a concern for you, you could consider the DuroMax XP11000iH, which is one of the least noisy generators in its power range, rated at 61 dBA.
  • As for its autonomy, the XP12000HX, with an autonomy of around 9 hours at a 50% load, is placed on the low end among the generators of its kind. If extended autonomy is what matters most to you, the Westinghouse iGen11000DFc could be an excellent choice, offering one of the longest run times among units in its power category, reaching around 12 hours.
  • Run time is crucial, but it heavily relies on the fuel tank's capacity. Thus, considering fuel efficiency alongside is essential. Compared to similar devices, this generator is less fuel-efficient than most: it burns around 0.92 gallons of gasoline per hour at a 50% load. If you wish to get a unit of similar power, but with one of the best fuel efficiency, you could consider the Westinghouse iGen11000DFc, which has an impressively low fuel consumption of 0.66 GPH.

Here's a list of the most popular specific comparisons:
