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 ensure that a power failure will not prevent them from working
Power & Run Time
The dual-fuel technology of the DuroMax XP12000EH allows for an output of 120/240V and provides superb power and versatility. If gasoline-powered, the device provides a running wattage of 9500W and a starting wattage of 12000W. If propane-powered, it gives 8075 rated watts and 10200 starting watts.
At a noise rating of 72 dBA (just slightly more noisy than a vacuum cleaner), this generator can be started via a simple traditional pull-start mechanism, or a simple and elegant electric starter (battery included).
With a fuel capacity of 8.3 gallons, the XP12000EH can operate for around 9 hours at 50% load using gasoline (fuel consumption around 0.92 GPH), or for around 4 hours (on a 20 lbs tank - propane consumption around 1.18 GPH) using propane.
Since the XP12000EH has a somewhat high THD (<12%), it is advisable to not use it for the powering of sensitive electronic devices.
The control panel provides the upcoming 5 AC outlets:
It also sports 1 DC outlet: there's a 12V 8A output allowing you to easily charge your batteries.
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, as it features a twist-lock L14-30R receptacle, the XP12000EH 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.
The dimensions of the DuroMax XP12000EH, which are L30 x W22 x H26 in, and its typical, open frame design provides stability and enables the generator 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 221 lbs. Nevertheless, thanks to its wheel kit and its folding handle (a decent solution to its lack of maneuverability), the generator can be easily moved, once placed the ground.
The XP12000EH and its control panel include a handy voltmeter that allows you to easily monitor power output anytime. This feature comes handy when monitoring its status and activity.
In addition to this info, a light indicator allows you to instantly see if its oil levels are insufficient.
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 overload protection (circuit breaker) and an automatic low oil shut-off, 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: tool kit, funnel and propane hose.
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 therefore, can be used 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 generators of similar power (between 9000 and 10000 W).
- As for its weight, the DuroMax XP12000EH weighs only 221 pounds, making it one of the lighter generators in the 9000-10000 rated wattage category. If weight is your top priority, one of the champions in this power category is the Rainier R12000DF, weighing just 196 pounds.
- With a lowest noise rating of 72 dBA, the generator is one of the more quiet of the generators of similar 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.
- The XP12000EH’s autonomy is somewhat low end compared to devices of its power range, as it reaches only around 9 hours at 50% load on a full tank. If concerned with autonomy, one of the products of a comparable power output, which offers the highest run time, is the Powerhorse 13000ES, boasting with 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. 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 you wish to acquire one of the most gasoline efficient products of this power range, the Rainier R12000DF, with a fuel consumption of 0.55 GPH could be in your good books.
Here's a list of the most popular specific comparisons:
As you can see from this interactive chart, when compared to other 9000-10000W generators, the DuroMax XP12000EH is on the cheap side of the price range.
It can therefore be a really good buy if you're looking to acquire a budget generator.
