Zoom on the DuroMax XP12000EH

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

  • Small homeowners in search of a full power backup solution
  • 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, and the extra features it benefits from.

Power & Run Time

The DuroMax XP12000EH in use

The DuroMax XP12000EH

The DuroMax XP12000EH, equipped with dual-fuel technology and delivering 120/240V, ensures both power and versatility. Running on gasoline, it delivers a running wattage of 9,500W and a starting wattage of 12,000W. On propane, it provides 8,075 running watts and 10,200 starting watts.

With a noise rating of 74 dBA (just slightly more noisy than a dishwasher), the generator features a manual recoil starter system, but also a convenient and easy-to-use electric starter (battery included).

Regarding its running time, the XP12000EH, with a 8.3 gallons fuel tank, can operate for up to 19 hours with a full gasoline tank (with fuel consumption estimated at around 0.44 gallons per hour). It also offers up to 7 hours (on a 20 lbs tank - propane consumption around 0.67 GPH) of operation when using propane.

As the XP12000EH exhibits a THD of less than 12%, which is relatively high, it is best avoided for powering sensitive electronic devices.

Outlets

The control panel is equipped with 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

Moreover, it comes equipped with 1 DC outlet: there's a 12V 8A output making battery charging a breeze.

Despite not meeting the 'RV Ready' criteria, this DuroMax generator grants the advantage of simple RV compatibility via its L5-30R receptacle, enabling you to conveniently power your RV by using an L5-30P to TT-30R adaptor. Besides, since it boasts a twist-lock L14-30R receptacle, the XP12000EH is engineered to be transfer switch ready, ensuring easy integration with your breaker box to provide backup power to your home during outages.

Portability

With its L29 x W30 x H26 in dimensions, the open frame structure of the DuroMax XP12000EH guarantees stability, simplified maintenance access to components, and better air cooling than enclosed units. The design is ideal for rough environments and demanding outdoor use.

While technically classified as 'portable' due to its ability to be moved, the 224 lbs of this generator make manual lifting and transportation incredibly difficult. 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

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, a light indicator on the device will signal if its oil levels are insufficient.

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

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).

Apart from the typical documentation and an owner's manual (opens in a new tab), which lets you start it right away, the DuroMax XP12000EH also is packed along with the following accessories: propane hose, tool kit and funnel. An official storage cover is also available, as a separate purchase.

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 dual fuel generators of similar power (between 9000 and 10000 W).

  • Weighing in at 224 lbs, the DuroMax XP12000EH is one of the heavier dual fuel generators available in the 9000-10000 rated wattage segment. If weight is an important consideration for you, the Westinghouse iGen11000DFc stands out as one of the top contenders in this power category, with a dry weight of 187.4 pounds.
  • As this generator has its lowest possible noise of 74 dBA, it should be considered noisier compared to its peers of a comparable running wattage. If noise emissions are one of your priorities, you may want to take a look at the DuroMax XP11000iH. It's one of the quietest options among generators of similar power, rated at 61 dBA.
  • As the XP12000EH features an autonomy of up to 19 hours at 25% load, it has a higher run time than an average generator of its type and power range. Furthermore, considering the run times, one of the generators which have a roughly same power output, with the highest autonomy, is the DuroMax XP11500EH, as it provides up to 20 hours.
  • Run time is a key metric, but it's dependent on the generator's fuel capacity. Therefore, discussing fuel efficiency is necessary to get the full picture. This generator is one of the more fuel-efficient models of the aforementioned output range, as its estimated fuel consumption reaches just 0.44 GPH (gallon per hour) at 25% load. If fuel consumption is your top priority, we suggest to check out the DuroMax XP11000iH, which has a fuel consumption of only 0.39 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 9000-10000W dual fuel 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.

    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

    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.
