Zoom on the DuroMax XP12000EH
In summary, the DuroMax XP12000EH is a powerful portable generator especially useful for:
- 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
In the sections ahead, the power characteristics, availability of various outlets, the portability, and any additional features of the device shall be discussed, including its emission compliance information.
Power & Run Time
Thanks to its dual-fuel technology, the DuroMax XP12000EH delivers 120/240V and offers power and versatility. When gasoline-powered, it benefits from a running wattage of 9,500W and a peak wattage of 12,000W. When propane-powered, it has 8,075 rated watts and 10,200 peak watts.
Enjoying a noise rating of 74 dBA (just slightly more noisy than a dishwasher), this generator can be started thanks to a simple traditional pull-start mechanism, but also to a simple and elegant electric starter (battery included).
The running time of the XP12000EH, with its 8.3 gallons fuel capacity, can reach up to 19 hours on a full tank of gasoline (fuel consumption around 1.04 GPH). With propane, it can reach up to 7 hours (on a 20 lbs tank - propane consumption around 0.67 GPH).
The quite high THD (<12%) of the XP12000EH makes it unsuitable for powering sensitive electronic devices.
The control panel features the upcoming 5 AC outlets:
It also sports 1 DC outlet: there's a 12V 8A output with which charging your batteries is made easy.
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, due to the featured twist-lock L14-30R receptacle, the XP12000EH is transfer switch ready: you may connect it to a breaker box to power your household during a power outage.
The DuroMax XP12000EH has a conventional, open frame design, of the following dimensions: L29 x W30 x H26 in, which offers support and allows it to be raised above ground level. The featured design is ideal for the outdoors and all tough environments.
While the generator is considered to be technically 'portable' (in the sense that you can move it), manually lifting and transporting it may be challenging, due to its high weight of 224 lbs. Nevertheless, it can still be moved quite conveniently with the help of its wheel kit (⌀10") and its folding handle, once it is placed on the ground.
The XP12000EH's status and activity may be monitored conveniently via the control panel, as it features a handy voltmeter that allows you to easily monitor power output anytime.
In addition to this info, a light indicator allows you to instantly see if its oil levels are insufficient.
The generator includes a built-in fuel gauge, a quick, easy and convenient method of checking the device’s gas level.
As for its security measures, the device features an overload protection (circuit breaker) and an automatic low oil shut-off, letting you use it with a peace of mind.
Besides the classic documentation and an owner's manual (opens in a new tab) to get you promptly started, the DuroMax XP12000EH also comes with some accessories: funnel, tool kit and propane hose are included. An official storage cover is also available, as a separate purchase.
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, so it is adequate for use in forested areas.
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).
- A weight of 224 lbs makes the DuroMax XP12000EH one of the heavier dual fuel devices in the 9000-10000 rated wattage range. If you are concerned by weight, one of the champions in the above-mentioned power range is the Pulsar PG12000B, with a dry weight of just 205 pounds.
- As this generator can emit noise as low as 74 dBA, it finds itself in the average expected noise for this kind of power. If noise emissions are important to you, one of the least noisy generators of this power range is the A-iPower SUA12000ED with only 69 dBA.
- Regarding its autonomy, the autonomy of the XP12000EH, reaching around 8 hours at a 50% load, can be considered as low end, compared to other dual fuel products of a roughly equal output. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Pulsar G12KBN, boasting with 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. This generator is rather wasteful, compared to other devices within the aforementioned output range, when it comes to gasoline consumption, as it reaches roughly 1.04 GPH at a 50% load. If not satisfied with the afore-mentioned fuel consumption, you may wish to check out the Pulsar G12KBN. With a fuel consumption of as little as 0.67 GPH, it is one of the most efficient generators currently on the market.
Here's a list of the most popular specific comparisons:
As you can see from this interactive chart, 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.
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.
