  • DuroMax XP12000EH Dual Fuel Generator
  • Battery (for electric start)
  • Wheel Kit
  • Maintenance Tool Kit
  • User Manual

Operation & Ease of Use

For those that have used a generator with a standard recoil starter before, you might have a clue on how tedious this task can be. Good thing the manufacturer found it wise to strap an electric starter to the DuroMax XP12000EH.

So, you can simply start up the engine with the turn of a key! What is even better is that the model also comes with the standard recoil starter in case the battery runs low – you get the best of both worlds!

The user panel of the XP12000EH presents you with great functionality and isn’t overly-complicated with what you don’t have to understand about gauges and switches. On it, you will find two regular 120V receptacles, similar to the outlets in your house, and a 30A 120V twist lock receptacle which comes in handy if you are a RV owner.

Also, there’s the high-current 120V/240V receptacle which you can connect to your main power distribution board through a transfer switch. No need to fret about overloads and the voltmeter lets you keep an eye on the voltage for the safety of your appliances.

Finally, there’s a handy 12V receptacle on the panel that you can use to charge batteries. As customary of most DuroMax generators, this model has a low pressure detection system that automatically shuts it down. What’s more? The huge rubber wheels and handles of the XP12000EH let you carry it wherever you want.

Noise Level & Power

The XP12000EH is fitted with a 457cc 18HP OHV engine. The power plant has a cast iron cylinder and steel bearings that help yield 9500 running watts to 12000 surge watts.

With its constant power output, you can supply electrical power to any regular household. As for its peak power capability, it can provide sufficient electric current for the high-power capacitor appliances, like fridges or any kind of machine that is strapped with an inductive current motor.

You can rely on it to present you with a run-time of about 20hrs at 50% Average Output – regardless of whether you are running it on propane or gasoline. For a powerful 255lbs generator, it delivers an almost quiet functionality; all attributable to its brilliantly-designed muffler.

Verdict: Should You Buy It?

The DuroMax XP12000EH is christened ‘The Beast’ for good reason - it’s a very powerful and durable portable gas generator with an amazing run-time. Aside from its reliability, the versatility this hybrid presents is distinctly advantageous over the conventional gas-powered generators.

Its ease of use, excellent safety features, and quiet functionality add on to why it might be the best portable dual fuel generator for you. That said, you might want to have a look at the standard DuroMax XP10000E model as a comparison product.
