Description

The XP12000X is the BEAST of the new lineup, with 12,000 peak watts and 9,500 running watts. (source: DuroMax (opens in a new tab))

Zoom on the DuroMax XP12000X

In a nutshell, the DuroMax XP12000X 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

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 XP12000X in use

The DuroMax XP12000X

The DuroMax XP12000X's engine, 457 cc OHV 4-stroke, fueled by gasoline, can deliver 120/240V. It provides a running wattage of 9500W and reaches a peak wattage of 12000W.

At a noise rating of 74 dBA (just slightly more noisy than a dishwasher), this generator can be started via a conventional pull-start mechanism, or a simple and elegant electric starter (battery included).

With a full tank, the XP12000X can operate for around 8.8 hours at 50% load (fuel consumption around 0.94 GPH), thanks to its fuel capacity of 8.3 gallons.

The powering of sensitive electronic devices with the XP12000X is not recommended due to its relatively high THD (<12%).

Outlets

The control panel features the following 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

Even if this DuroMax generator isn't quite RV Ready, it still allows for an easy RV connection via an L5-30P to TT-30R adaptor, thanks to its L5-30R receptacle. Besides, as it features a twist-lock L14-30R receptacle, the XP12000X is transfer switch ready: in case of a power outage, you will be easily able to connect it to a breaker box and power your household.

Portability

The design of the DuroMax XP12000X is a typical, open frame, with the dimensions of L29 x W30 x H26 in, offering support and stability and enabling the possibility of raising it above ground level. The generator is designed for ideal use outdoors and in rough environments.

As the generator's weight is 230 pounds, manually moving it or transporting it may be challenging, despite the fact that it is technically considered 'portable' (movable). However, this lack of maneuverability is compensated by its wheel kit and its folding handle, with which you can conveniently shift it, once it's on the ground.

Features

The XP12000X's control panel

To help you monitor the XP12000X's status and activity, its control panel is equipped with a convenient meter, which displays voltage, frequency and lifetime hours.

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

The generator allows for a quick, easy and convenient assessment of its gas level, as it is equipped with a 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.

The XP12000X 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. It’s a welcomed additional security feature, but don’t forget to always take your generator outside (opens in a new tab).

Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the DuroMax XP12000X also comes with some accessories: tool kit and funnel are included.

Emissions

The DuroMax XP12000X 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 and thus, may be used in forested areas.

Product Video

The DuroMax XP12000X versus other generators

The following charts are provided to give you an idea of how some of the key specs of the DuroMax XP12000X compare to generators of similar power (between 9000 and 10000 W).

  • Since the generator weighs in at a dry weight of 230 lbs, the DuroMax XP12000X belongs in the expected weight range for devices which can produce between 9000 and 10000 rated watts. Regarding dry weight, one of the champions in the same power range is the Pulsar PG12000B, with a dry weight of only 205 lbs.
  • This generator has a somewhat average expected noise for its power range, 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 SUA13000EFI, whose lowest noise levels reach just 69 dBA.
  • Regarding its autonomy, the autonomy of the XP12000X, reaching around 8.8 hours at a 50% load, can be considered as low end, compared to other products of a roughly equal 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 Powerhorse 13000ES, with around 15 hours.
  • Even though run times are undoubtedly important, they are dependent on the fuel capacity to a large extent. For a more wholesome picture, we must take into consideration the fuel consumption of the generator. This generator is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.94 GPH at a 50% load. If you wish to acquire one of the most gasoline efficient products of this power range, the Westinghouse WGen9500DF, with a fuel consumption of 0.55 GPH could be in your good books.

Price comparison

As you can see from this interactive chart, when compared to other 9000-10000W generators, the DuroMax XP12000X is on the average side of the price range.

Therefore, this generator nicely fits in the expected budget for this kind of product.
