Zoom on the DuroMax XP12000EH

In a nutshell, the DuroMax XP12000EH is a powerful portable generator mostly geared towards:

  • Prudent homeowners who want a backup power source in case of a power outage
  • Professionals who want to be able to deliver results, even during a power failure

The following sections will present you in detail its power characteristics, the different outlets it offers, its overall portability, the extra features it benefits from, and any relevant emission compliance details.

Power & Run Time

The DuroMax XP12000EH in use

The DuroMax XP12000EH

With its dual-fuel technology, the powerful and versatile DuroMax XP12000EH provides an output of 120/240V. While gasoline-powered, it gives a running wattage of 9500W along with a peak wattage of 12000W. While propane-powered, it provides 8075 rated watts and 10200 starting watts.

The generator is rated for a noise of 72 dBA (just slightly more noisy than a vacuum cleaner). Its starting mechanisms include a conventional pull-start mechanism and a convenient and easy-to-use electric starter (battery included).

As for its running time, the XP12000EH, along with its 8.3 gallons fuel capacity, can run for around 9 hours at 50% load with a full tank filled with gasoline (fuel consumption around 0.92 GPH). If propane is used, it can operate for around 4 hours (on a 20 lbs tank - propane consumption around 1.18 GPH).

The powering of sensitive electronic devices with the XP12000EH is not recommended due to its relatively high THD (<12%).

Outlets

The control panel includes 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

In addition, it provides 1 DC outlet: there's a 12V 8A output with which you may charge your batteries with ease.

Even though this DuroMax generator isn't quite RV Ready, its L5-30R receptacle allows an easy RV connection via an L5-30P to TT-30R adaptor. Besides, because the XP12000EH 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 XP12000EH offers stability and allows the generator to be raised above ground level. The design is ideal for rough environments and demanding outdoor use.

Although this generator is technically considered 'portable' (in the sense that it can be moved), its 224 lbs make it incredibly difficult to manually lift and transport. 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

Panel of the DuroMax XP12000EH

The XP12000EH's control panel

The control panel of the XP12000EH includes a handy voltmeter that allows you to easily monitor power output anytime, helpful for the monitoring of its status and activity.

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

A built-in fuel gauge allows for a quick, easy and convenient check of the fuel level of the generator.

As for its security measures, the device features an automatic low oil shut-off and an overload protection (circuit breaker), letting you use it with a peace of mind.

Along the basic documentation and an owner's manual (opens in a new tab), useful for starting the generator right away, the DuroMax XP12000EH's package also includes these accessories: funnel, propane hose and tool kit. An official storage cover is also available, as a separate purchase.

Emissions

The DuroMax XP12000EH 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 Videos

The DuroMax XP12000EH versus other generators

The following charts are provided to give you an idea of how some of the key specs of the DuroMax XP12000EH compare to generators of similar power (between 9000 and 10000 W).

  • Regarding its weight, the DuroMax XP12000EH only weighs in at 224 pounds, which means it's one of the lighter generators in the 9000-10000 rated wattage range. Regarding dry weight, one of the champions in the same power range is the Rainier R12000DF, with a dry weight of only 196 lbs.
  • With a lowest possible noise of 72 dBA, this generator places itself amongst the more quiet of the products delivering similar power. 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.
  • As for its autonomy, the XP12000EH, with an autonomy of around 9 hours at a 50% load, is placed on the low end among the generators of its kind. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the Powerhorse 13000ES, as it provides around 15 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 is not fuel efficient compared to devices of similar output: its estimated fuel consumption stands at 0.92 GPH at a 50% load. If fuel consumption is your top priority, we suggest to check out the Westinghouse WGen9500DF, which has a fuel consumption of only 0.55 GPH and thus, is one of the most efficient devices in our database.

Price comparison

As you can see from this interactive chart, when compared to other 9000-10000W generators, the DuroMax XP12000EH is on the average side of the price range.

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

Does the DuroMax XP12000EH Duel Fuel Portable Generator have a bonded or floating neutral? (Asked May 13, 2020)

According to DuroMax, the neutral is floating.

What is the oil tank size of the Duromax xp12000eh? (Asked May 19, 2020)

The unit's engine oil capacity is 37 fl. oz.

can the dura max handle a 230 amp 3hp well pump submersible (Asked November 25, 2020)

Assuming that you meant "230V" and not "230 amp", it could probably be fine via the 14-50R outlet. However, you'd need to check the actual amp draw of your appliance, especially when starting it up. You may find more information on how to do it in this article.

what type of oil does it take (Asked July 28, 2021)

For general all-temperature use, SAE 10W30 is recommended.

    Great generator! Has it all; fuel consumption is on the high side though. One disturbing fact: the literature says it is a floating neutral generator, but a quick continuity test proves otherwise—it is bonded neutral from the factory. DuroMax needs to get their story straight on this as it is putting people at risk who are using the generator as a back-up power source wired to a house’s primary breaker panel.

    + PROS:
    • Lots of features, relatively quiet,
    - CONS:
    • High fuel consumption rate; misinformation about the bonded/floating neutral.

    First generator was a Honda 4000 watt. Great for its intended use. But not intended for full home backup power. So bought this one and haven’t looked back since. Have used it 3-4 times during power outage. It runs all essential home appliances with exception of water heater. Certain it will run that to. Just haven’t needed to yet. Longest outage was 10 hrs.

    + PROS:
    • Great generator. Would buy it again
    - CONS:
    • Chinese battery & cables are cheep Chinese garbage. Replaced with a Duracell 350 CCA. And heavier cables. Battery is bigger than oem so won’t fit oem spot. So put it in portable battery box on floor in cart I built for generator. Replaced no flats with air filled tires. Other than above mentioned. Have no complaints. FYI using Amsoil full synthetic engine oil since 1st fill
