Power & Run Time

DuroMax XP12000EH is in use. Power and runtime.

The problem among most portable generators is that usually they are designed for being used either at remote locations or construction sites where the users only need to run a few small electrical devices or appliances.

Most of these generators are not meant to be used as backup power at home supply as their total energy output is way too low. Duromax is famous for its half-load run time, which can run on propane and gas.

Exceptionally, ultra-duty portable inverter generators can manage to handle a larger electric load. However, there are very few generators with 10000 watts of engine power and they usually cost a lot.

Duromax XP12000EH inverter generator is one of the very few generators of this size range that actually performs great and does not cost much.

Its huge 12,000 starting watts is enough to run the most complicated and delicate household appliances without the risk of being overloaded. Also, it is powerful enough to generate a most demanding electric tool 230 Amp MIG welder.

This generator is a better selection than those that rely solely on gas. That’s because first of all, running a generator on propane is greatly cheaper than gas.

This will save you a lot of money that would have been spent on fuel. Secondly, the availability of both fuels allows you to be more flexible and you will get a longer runtime as you don’t have to worry about refueling the generator constantly.

Duromax XP12000EH generator has a run time of 15 hours continuously on both types of fuels combined. This is a massive advantage during a power outage. Switching between fuel types is also very easy.

It is only a matter of a push of a button. The generator also contains an optional recoil start.


The Duromax XP12000EH RV-ready generator contains dual-fuel technology and an 18HP 457cc watt OHV engine which is capable of producing up to 12000-watt starting watts while running on gas and 11,400 watts on propane.

Its fully loaded power panel carries a big number of outlets. This wheel Kit featured generator includes a 120V and 240V 50 amp heavy-duty outlet, a 120V twist-lock outlet, a 120/240V 30 amp twist lock, and dual 120V 20 amp household outlets.

As you can see it is designed to run a huge range of tools and essential appliances and even the high-power desired electronics. Contains a panel with an oil warning light that displays the remaining fuel level.


DuroMax XP12000EH portability

One thing that makes the consumers worry before purchasing this generator is that the generator is very heavy and quite not easy to transport.

Unless you are a strong and fit person, you have to find somebody else to help you move it around. At 260 lbs it’s among very few generators on the market that are topping at present and achieving consumer satisfaction.

But this is not a big matter of concern for those who can consider this a small issue compared to its highly beneficial sides.
