Honest DuroMax XP12000EH Review

This DuroMax XP12000EH review is based on 15 months of usage in different scenarios and situations. I also wrote an initial review after using it for 6 months in the 50 amp generator article. The reading of noise and runtime tests are pretty much the same, and the performance is up to the mark as well.

DuroMax XP12000EH is one of the most versatile, durable, powerful, and reliable hybrid backup generators on the market.

There is an argument that DuroMax XP12000EH is the best 1200W heavy-duty generator thanks to its 457cc overhead valve engine that produces 18HP.

This thing produces 12000 starting and 9500 rated watts on gasoline, and 11400 starting and 9025 rated on propane. This power is 100% true. I have tested the power output multiple times.

It is often compared to standby generators because there is no installation cost, it is portable, equally powerful, and cheaper.

It is often recommended for small houses that face prolonged power outages.

I am not saying you should purchase DuroMax XP12000EHover Generac champion whole house generators, but if you end up purchasing one, trust me it will not be a bad decision.

It starts smoothly. No bad vibrations or weird noises are coming from the engine or the frame. It features both manual and electrical start. So far I don’t have any problems with the starting system.

Design oF DuroMax XP12000EH

DuroMax is built from the highest quality material. This thing is absolutely solid. The open metal frame design is heavy-duty. The motor mounts also serve as a protective casing for the machine.

This 12000W generator weighs 224 pounds which is not lightweight by any means so don’t even think about lifting it. To move it around, it has a nice ergonomic handle and wheels.

The only complaint I have is with those wheels. I don’t like them at all so I replace them with my own 10” diameter wheels.

Many people have complained about the wheels too I decided to contact one of their officials about the wheels. The response was positive. I am hopeful they will improve it in their future models.

The control panel is neat and clean with GFCI outlets. It features:

  • An analog volt meter
  • X2 5-20R
  • L14-30R
  • 14-50R
  • 12V post
  • MX2 switch
  • Low oil sensor
  • Switch start

8.5/10 for design.

Noise Test of DuroMax XP12000EH Backup Generator

XP12000EH is not a small generator by any means and it is an open frame. So if you are not expecting a silent performance, you are wrong.

After testing the noise multiple times during my previous Duromax XP12000EH review, the results were:

  • From the distance of 5 feet under no load, the noise levels were 88 to 90dB.
  • From the distance of 30 feet under no load, the generator made 75 to 76dB of noise.

The results after 15 months of use:

  • From the distance of 5 feet under no load, the noise levels were 89 to 90dB.
  • From the distance of 30 feet under no load, the generator made 75 to 77dB of noise.

This is not bad at all. You are going to use the generator at least 25 to 35 feet away from the house anyway, so don’t worry about the loud noise. 8/10 for noise.

Runtime Test (Fuel-Efficiency) Test of DuroMax XP12000EH

After the use of 5 months, I conducted a runtime test of propane and gasoline. The results were:

  • 8.5 hours at 55% load on gasoline
  • 7.3 hours at 55% load on gasoline

After 15 months, I decided to increase the load for this test to check its durability. The results are:

  • 8.2 hours at 60% load on gasoline
  • 7.1 hours at 60% load on propane

Again, I was surprised by the results even after 15 months. I was expecting a good runtime but not this good. 8.8/10 for runtime.

Load Test:

This generator is equipped with a 457cc 4-cycle air-cooled engine. During my load test, I managed to get 9489 rated watts on gasoline after putting it under 10,000W of load.

The maximum I got on gasoline was 9511 rated watts before the overload sensor.

On propane, I managed to secure a maximum of 9021 rated watts which is not bad at all. It wasn’t able to cross the 9025W limit on propane which I was hoping for.

9/10 for the load test.

I have been able to run the following devices on this generator during outages in my cabin:

What is the Performance of DuroMax XP12000EH?

So far, I have been able to run everything in my RV, travel trailer, garage, and cabin. I have also used it for emergency backup during power outages. This generator can run for hours and hours continuously.

So I have also tested its recovery time, from low voltage to high voltage, it recovers in a flash which is always good whenever you are going to power motor-driven appliances.

I also like the MX2 technology. I use many power tools and heavy-duty appliances in my cabin, MX2 technology allows me to get the maximum power from each of the 120V receptacles.

One of the biggest selling points for me was the runtime. I have been able to power my small cabin for an hour regularly during cloudy days.

The problem I see is the crappy wheelset that should be fixed in future models, and the battery doesn’t always come fully charged so you should keep that in mind.

Who Should Buy DuroMax XP12000EH?
