About Duromax XP12000EH – At a Glance

The Duromax is might be a good choice for those who don’t want to go through stand-by a generator due to hassle its maintenance, big size, not portable.

This model provides a massive power that makes you able to run your home appliances or heavy tools at job sites.

The Duromax xp12000eh is also a good generator like its big brother duromax xp13000eh.

Thanks to the Duromax company that gives dual fuel feature in this heavy duty generator. Mean you have facilities to run this generator by propane or liquid propane in emergencies.

You’ll not need to stay in petrol to bring petrol when there is petrol shortage due to bad weather or petrol prices.

The generator is equipped with so many outlets that’s why the duromax xp12000eh is a winner in every area.

It is like an all-rounder that can be used for many purposes especially home backup, RV trips, and construction sites.

Very solid design with steel frame so that the generator can ready to fight any hard place and weather.

Despite big size generator, it is still portable there is not hassle to move around it.

As a general respective, this model has 2 methods to start the unit – electric start and manual recoil start. This is not a big change because every big generator must have an  electric start.

But there are some amazing features which I like in this model very much and those features are must be appreciated according to my opinion.

Let’s see how many amazing things are equipped in the duromax xp12000eh.

What I like about Duromax XP12000EH Dual Fuel Generator?

EPA & CARB Approved

Sometimes it happens that you have purchased the generator but you have become a limited person with that generator.

Because you’re not allowed to use the generator in some states of the USA like California.

Often this problem comes with large size generators and this might be a big issue for California’s people.

Now the Duromax has solved this problem for California and all over the world.

The Duromax XP12000EH comes with EPA and CARB approved so that it can be used all over the world.

You can use the big size generator where you want in the USA even also California.

This feature is a surprise for those people who are not allowed to use every type of generator.


duromax xp12000eh review

The 2nd shocking feature which I like very much in this generator is this model is fitted with several types of outlets.

If you like to go RV trips several times then it might be a very good option for you because it has one 120V 30amps twist lock outlet, and another one is 120/240 volts 30amps twist lock outlet.

I don’t think you’ll not like this model for RVs or camping.

For heavy-duty tools or appliances, it is fitted with one 120/240V 50amps heavy-duty outlet.

Also, there are two 120 volts 20 amps standard outlets so that you can power your home.

Heavy Power Output

Most portable generators don’t provide much power to run your big-size tools or appliances.

They are just able to run your small tools or a few appliances at home.

If they provide few more power that can run some big-size tools or appliances then you have to invest few more money.

But the Duromax ex12000eh has a big size 457cc OHV 4-stroke engine that generates 12000 surge watts and 9500 starting watts.

As you know this model has a dual fuel feature. However, “The Beast” generates 11400 surge watts and 9025 running watts while running on propane.

Cheap Price

Generally, we think that if the generator has designed for heavy-duty it must be very costly.

But the Duromax xp12000eh seems to be a breaker of this rule since it is not an expensive generator while it is a dual fuel, and a very solid generator.

You can purchase this model for under 1500$, and this price is not costly for anyone. You can easily light your house during the blackout days for just under 1500$.

This is an amazing feature of this model that despite a huge power operation, it still comes at a reasonable price.

Is there any downside to Duromax XP12000EH?

As same like other portable generators, this generator is also not safe for all sensitive electronic appliances.

You’re not allowed to connect any modern type appliances at your home.

The XP12000EH generates a 74 dba noise level at quarter load.

However, if the generator runs on full load so it will be very loud like other heavy-duty generators.

Duromax designed this model with a steel frame body, also it has a big size engine that’s why the generator weight is 224 pounds.

Maybe you’ll have an issue moving around it.

  • Long run time
  • Sturdy Design
  • Steel Frame
  • Dual Fuel Feature
  • Very Affordable Price
  • High Power Output
  • Best for Home Back up
  • It might be loud at full load
  • May be you’ll not like its wheels
  • Costumer service not good

Conclusion – Why you should buy Duromax xp12000eh?

As its nickname “the beast” it really works like that.

For those who are looking for a generator for overall home up, this model will be fit for their usage.

The best reason for selling this model is it is not a costly generator like other brands and standby generators.

Having a sturdy design due to the steel frame, and a long run time that will help you during a power outage.

Since it is a dual-fuel generator that’s why you can run it for a very long time. Also, it can be used for a long time since it has a unique technology that keeps cool the engine as much as possible.

There is no serious complaint related to a product or its function except the customer service might be bad.

Also, maybe you’ll not have any problem with wheels.
