Zoom on the DuroMax XP12000HX

In short, the DuroMax XP12000HX is a powerful portable generator adequately designed 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 sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed.

Power & Run Time

The DuroMax XP12000HX in use

The DuroMax XP12000HX

With its dual-fuel technology, the DuroMax XP12000HX delivers 120/240V, and offers power and flexibility. Running on gasoline, it boasts a running wattage of 9,500W and a peak wattage of 12,000W. When powered by propane, it delivers 9,025 running watts and 11,400 peak watts.

Featuring a noise rating of 74 dBA (just slightly more noisy than a vacuum cleaner), the generator is equipped with both a manual recoil starter system and a convenient and easy-to-use electric starter (battery included) for starting.

As for its running time, the XP12000HX, along with its 8.3 gallons fuel capacity, can run for up to 19 hours with a full tank filled with gasoline (fuel consumption around 0.44 GPH). If propane is used, it can operate for up to 7 hours (on a 20 lbs tank - propane consumption around 0.67 GPH).

Given the XP12000HX's relatively high Total Harmonic Distortion (THD) of less than 12%, it is advisable to avoid using it to power sensitive electronic devices.

Outlets

The control panel includes 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

This DuroMax generator isn't quite RV Ready, but it features an L5-30R receptacle, allowing a simple RV connection through an L5-30P to TT-30R adaptor. Besides, equipped with a twist-lock L14-30R receptacle, the XP12000HX is engineered to be transfer switch ready, enabling simple hookup to your breaker box to provide backup power for your home during blackouts.

Portability

At L29 x W30 x H26 in, the DuroMax XP12000HX boasts a traditional open frame structure, ensuring stability and allowing for convenient maintenance access to components, promoting air circulation. This type of design is ideal for tough environments and heavy outdoor use.

Despite its weight of 230 lbs, the generator is still considered 'portable,' meaning it is movable, although its heftiness may restrict portability in certain environments or require additional considerations for transportation and setup. 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 XP12000HX

The XP12000HX's control panel

To facilitate status and activity monitoring, a convenient meter, providing voltage, frequency, and lifetime hours data are embedded in the control panel of the XP12000HX.

In addition to this info, a light indicator serves to show you when the oil level is too low.

Thanks to its built-in fuel gauge, the generator allows you to quickly, conveniently, and easily check the gas level at a glance.

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 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.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the DuroMax XP12000HX's package also includes these accessories: tool kit, propane hose and funnel.

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).

  • As its dry weight is 230 pounds, the DuroMax XP12000HX is one of the heaviest of the dual fuel products which can generate 9000 to 10000 running watts. If weight matters to you, one of the champions in this power range is the Westinghouse iGen11000DFc with only 187.4 pounds.
  • This generator, with its lowest noise level at 74 dBA, is noisier than most generators of comparable running wattage. If noise level is one your key decisive factors, you may find the DuroMax XP11000iH appealing. It's rated at 61 dBA, making it one of the quietest generators in its power range.
  • At a 50% load, the XP12000HX's around 9 hours of runtime on a full tank fall within the average autonomy range for similarly powerful dual fuel generators. If run time is one of your main concerns, the Westinghouse iGen11000DFc could be worth looking at. It boasts one of the highest run times among units of comparable power, lasting around 12 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. Compared to its peers, this generator is not exactly fuel-efficient, compared to similarly powerful devices, with an estimated fuel consumption of 0.92 GPH at a 50% load. If fuel consumption is your top priority, we suggest to check out the Westinghouse iGen11000DFc, which has a fuel consumption of only 0.66 GPH and thus, is one of the most efficient devices in our database.

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