Duromax XP13000EH vs XP12000EH – What’s the same?

Type & Technology

Unlike normal generators, both devices work with dual-fuel technology. So, you can use gasoline and propane to generate power. Propane is much harder to come by, but makes less noise when run and doesn’t emit smoke, unlike gasoline. 

Tank Capacity

Each generator uses a fuel storage tank and higher capacity helps the generator run for a long time. Both Duromax generators are available with a high gas tank capacity of 8.3 gallons and 40 lbs of propane tank support.


On average, you can use both Duromax generators for 8 hours on gasoline and 6 hours on propane with a full tank. Generally, a runtime of more than 7 horses without rest is considered ideal for any normal customer. So, the generators are perfect to power any device for a long period during a power outage.


Both generators have the same design and one-side controls. All functions, buttons, and power outlets can be used from the control panel of each generator. There is also an auto-off feature to help you save fuel and electricity when the generator is not running.


Surprisingly, both Duromax generators come with a three-year warranty to cover any defects in the product. However, the warranty is limited to some parts of the dual fuel generator, so you should check before using it.


Both generators are EPA (Environmental Protection Agency) and CARB (California Air Resources Board) certified. This means Duromax generators follow strict guidelines to make the device as echo-friendly as possible to help reduce pollution around the world.

Duromax XP13000EH vs XP12000EH – What’s so different?


Both Duromax generators offer a 4-stroke engine with spark ignition. However, you do get 500cc horsepower with the first device, while the second reaches a maximum of 457cc. They can deliver the same RPM but under load, the Duromax XP13000EH will win against the other. 


Depending on what fuel you choose to use, you’ll get different performance from each device. In Peak or Normal mode, the Duromax XP13000EH gives you more power, up to 13,000 watts. There are also five different outlets you can use to connect the generator to multiple devices.

Oil Capacity

All generators are equipped with an oil tank to lubricate any moving parts and prevent rust from damaging the metal. The Duromax XP13000EH has a larger oil capacity of 1.2 liters while the other device remains at 1.1 liters due to the smaller tank size.

Noise Levels

Most people forget to check the noise level of a generator before buying it, but this can be an important issue. Both Duromax generators produce less noise, but the second unit is slightly quieter. With the XP13000EH you hear an average volume of 74 dB, whereas the second device only delivers 72 dB due to a quieter engine block.


The Duromax generators have different models but are available with the same black and blue color option. Apart from that, the overall design and build of the two generators are very similar to each other, with the exception of a higher weight for the second model.
