Duromax XP12,000EH Dual fuel generator review: 2020

In the market for a high powered home generator that is still portable? The Duromax XP 12,000 EH dual fuel generator is a very strong contender to consider.

A home generator is one of those great investments. When the lights go out you want your family to be safe. With the storms rolling through the states getting stronger every year there has never been a better time to get a generator setup.

The Duromax XP 12,000 EH

Being in the market for a new generator this model kept showing up in just about every article I could find. Boasting a monster 18 horsepower, 457 cc overhead valve engine and a rating of 12,000 watts, this thing is nicknamed the beast, for good reason.

I am always honest with you guys and gals so I first want to tell you how I ended up with this machine. I was in the market for a home generator, I had an older 8,500 watt unit that worked good. The issue with that machine is it was very heavy as it was designed mainly for construction site use, good power but impossible for my wife to move outside if needed, heck even I dreaded moving the monster.

Time for a change

So as it goes, my neighbor had this unit. He decided to install an automatic standby unit to make power outages a total thing of the past. I purchased this from him with just about no hours on the engine. Lets check out some specifications.

  • weight= 236 pounds
  • Dimensions= 40 x 29 x 27.5 inches
  • 7.9 Gallon fuel tank
  • Can be hooked up to propane tanks of any size, (may need adapters)

The first thing I needed to do was get a set of wheels, the foam filled tires that come with this unit are literally junk. I am shocked a generator that seems to be made well that has great features would come with such poorly made tires. Seriously it’s not even a question, if you buy this generator order the wheels at the same time, the size I used is 10 inch diameter and 5/8 axle size. You can find some by clicking >HERE<

If the generator sits for any length of time the tires develop flat spots, I had to put the new wheels on before I could even roll it home.

The tires are junk !

Aside from the tires I have been very impressed with this generator. I was lucky because the setup work was already done for me. The first thing you will need to do is remove the shipping braces, these braces prevent engine movement during shipment. You will need to flip the generator over and remove the brightly colored brace, and the wood brace under the generator.

The next step is to add engine oil, I used the Redline oil found below, click the picture below for a link to order. 10w30 is the recommended weight for this generator. Redline is a very high quality oil that will stand up to the demands of the large 457cc engine. One thing I do want to note here, don’t go cheap on the oil, when the generator is operating the engine is running around 3600 rpm. This can be for a long duration if you have a long term power outage, you need oil that will not break down.

You will also have to install the wheels, again I would not install the ones that come with the generator.

A packet containing the following items comes with the generator

  • Double sided screwdriver
  • Two spanner wrenches for general maintenance
  • Spark plug wrench
  • Oil funnel with hose
  • DC charging cables
  • Plug ends (for making power cords)

Next hook up the battery, most likely it will be discharged you may need to charge it up overnight. The unit does come equipped with a pull start as well.

Time to start it up! This is one place where for the price, this unit really shines. Propane fuel capability come standard and ready !

Very well built machine that has the power of some standby units.

Aside from the terrible wheels I think Duromax has a home run here. The provided plug ends seem cheap, I would probably invest in a good quality generator cord, rated for 50 Amps such as the one found >HERE< Of course you need to check your own application to determine which cord setup works for you. I will be posting on interlock kits and setting up the electrical portion to the house in a later post.

Another thing that I really like about the Duromax XP 12,000 EH is the noise level, at <74 db, its pretty quiet considering how much power it produces. This is a major plus, especially in long term outage situations.

Lets take a look at some more specifications, impressive to say the least.

  • Rated wattage AC (gasoline) = 9,500 watts
  • Rated wattage (propane) = 8075 watts
  • Surge wattage (gasoline) =12000 watts
  • Surge wattage (propane) =10,200 watts
  • AC voltage 120/240V
  • frequency 60hz
  • AC phase single
  • DC voltage 12 volts
  • DC amperage 8.3 Amps
  • Run time @ 50% gasoline = 10 hr
  • Run time @ 50% propane = 5 hr 5 gallon
  • Oil capacity 37 fl ounces (1.1L)

Duromax really hit it on the head with this model, they have made an affordable generator that has very big power for the price paid. The power is clean, I can power just about my whole house with this unit and its clean power. I have not had any issue with sensitive electronics or anything to be honest. You could get a higher end brand, such as a Honda, but the price point will rise. The Honda below is a 10,000 watt model that is $5,200, click the image for more details. No doubt it’s a superior generator but the price difference is huge.

Whats the final word Scoot?

In terms of ratings lets see how this generator stacks up, below is a list of grades, 1 being terrible and 10 being great.

  1. Initial quality = 8.5 This generator is well made. I am impressed with the quality.
  2. Power = 10 This thing is a beast, it is a powerful unit.
  3. Price = 10 At around $1200 it’s hard to beat for what you get.
  4. Ease of use = 8 The generator is easy to start and operate. The only issue with propane use is it has a slightly lower wattage rating on propane.
  5. Overall = 9 For the money it’s hard to beat. Good quality and power for the price.

Different views on Duromax and their customer service, have been so – so I have not needed to contact them so I can not honestly say.

If you are looking for a powerful generator without breaking the bank, check out the Duromax XP 12,000 EH, I don’t think you will find a better generator for the price. Just make sure to hook it up to your house correctly, break it in right, and change the oil to a high grade synthetic. And for god sake get some new wheels!
