Engine capacity and wattage

DuroMax has nicknamed this product “The Beast.” That’s because the XP12000EH model packs enough power to function as a standby generator but instead comes in a neat, portable size.

Its central feature is its 457-cc, 18-horsepower engine. This engine is capable of generating 12,000 W starting wattage and 9,500 W running wattage. So, you can confidently plugin heavy-load appliances like your refrigerator or even your central air conditioning. This power level is especially useful in emergency situations such as storms or outages.

Aside from its big engine capacity, the Duro Max XP12000EH generator is easy to use. You only need to push a button on the control panel to start it electrically. Alternatively, you can just pull the recoil mechanism on the engine.

What’s more, this portable generator has a built-in muffler. This muffler keeps the noise level at 74 decibels, meaning this generator is only as loud as a dishwasher.

Fuel consumption

Thanks to the DuroMax Dual Fuel Technology, this portable generator can run on two types of fuel: gasoline and liquid propane. This means you can choose to use whichever fuel type is more convenient for you.

Based on the product information available on their website, however, it seems propane is the preferred fuel type. Reasons given include propane being cheaper and having a long storage life.

If you choose to fuel your DuroMax XP12000EH with gasoline, you can fill the tank up to 8.3 gallons. With this amount, you can expect this portable generator to give you power for nearly nine hours on half load. On the other hand, it can run for around seven hours on a half load of liquid propane. DuroMax recommends you use a 40-gallon propane tank with this generator.


Another factor that makes the DuroMax XP12000eh beast dual fuel portable generator interesting is it’s designed with MX2 Technology. This means you can run this portable generator on 120V and 240V simultaneously.

Alternatively, you can operate it on just 120V but with double the power. All it takes is a flick of a switch on the control panel. This is a useful feature to consider if you’re buying this generator for your RV.

You’ll additionally find five outlets in the control panel of The Beast: two 120V 20A GFCI outlet, one 120V 30A twist-lock outlet, one 120V/240V 30A twist-lock outlet, and one 120V/240V 50A heavy-duty outlet. These outlets allow you to have maximum compatibility between this generator and your appliances and machines.

Ideal usage

Given its specs, the DuroMax XP12000EH is perfect for situations that require you to power up heavy-loading devices at once. You’ll want to have a portable generator like this around during storm season when there’s a high chance of power outage in your area.

You can use this to keep your home comfortable even when an outage occurs, as it will let you run your essential appliances and your air conditioning.

If you need a powerful workhorse for your outdoor worksite, this DuroMax product can fit your needs. Moreover, you can easily transport it from site to site, as it comes with its own durable wheel-and-handle kit.

And if you’re an avid RVer, you can power your lifestyle with this portable generator. It’s not a lightweight generator, but its compact build means you can tuck it away inside your RV. You won’t find it hard to hook up The Beast at your campsite either.

The Beast may not look out of place at a tailgate party. However, it’s obviously overkill to bring it to a tent-camping trip.
