Additionally, available on the power panel are individual circuit breakers to keep everything safe by preventing overloading. This also contributes to quieter operation.

This means less pollution and certainly less black and oily smudges to clean. Its throttle is set at auto control to maintain the fuel efficiency of your unit.


DuroMax Generators are the ideal choice for any application where you need portable power. It doesn’t matter whether it’s due to a natural disaster or when you want to go camping, DuroMax always delivers. Nicknamed the ‘beast’, DuroMax XP12000EH provides the kind of power you would normally get from standard home standby generator units but this one is available in a portable package! The cost, including the cost of the electrician, cord, three propane tanks, generator cover, and the trickle charger all fall below $1500.

More than one DuroMax XP12000EH review has rated “The Beast” highly and for good reason. It is an extremely efficient generator that will power your entire house in case of an emergency or power outage. Because you can use propane, this translates to a cleaner carburetor thus contributing to environmental health. Propane is also certainly a lot safer to move as it doesn’t spill and is safely contained inside the dependable XP12000EH steel tank.

You can never expect to get a generator capable of giving such a power output that is completely silent no matter the brand or model. However, the brilliantly designed muffler and the noise-free exhaust means that the unit’s noise levels are surprisingly low when you consider this machine’s calibre.

Are There Any Drawbacks Worth Noting?

While the XP12000EH is a very dependable emergency generator, you may need to note the following points. For a portable generator unit, this model is rather on the heavier side at 250 lbs although it does come with wheels. While operating the DuraMax, several DuroMax XP12000EH reviews have reported that it tends to make a popping sound that can be scary because you might think something is going to blow up, but don’t worry.

It is also important to realize that below 40 degrees, propane diminishes. The cylinder is also not strong enough to propel the gasoline through when starting so you may need to start the generator using gas for the initial minutes prior to shifting to propane.

The user manual recommends changing the oil monthly or every 20 hours or monthly. From my own review, this is certainly needed and you must not put it off because similar to any engine, the dirty oil will cause the generator engine to overheat, eventually causing much damage.

Being a Non-CARB unit, it cannot be shipped to you if you are in California.
