Duromax XP12000E Generator - A Comprehensive Overview

Duromax Generator as you know that manufactures in Ontario, California. It was established in 2003 and is now regarded as one of the top manufacturers of portable gasoline generators. It offers top-notch generators that are appropriate for a variety of functions. Along with generators, their selection includes engines, pumps, pressure washers, and various accessories. The Duromax generators are renowned for their sturdiness and relatively extended runtime.

All the products from Duromax are also known for being reasonably priced. They are on the more affordable end of the pricing range compared to other manufacturers’ generators and have the same quality.

In this article, I have reviewed the well know Duromax Generator XP12000E which is very reasonable, sturdy, and efficient in working. You can run many household appliances o this gigantic generator. You can also assume it as a backup or while house generator.

While experimenting with this generator I have observed its many qualities and very few downsides that I am going to discuss below. So keep up with me to get to know each and everything about this generator.

Key Features

This generator is best to provide you with efficiency, adaptability, convenience, and durability. Let’s now examine the characteristics that make the DuroMax XP12000EH a workhorse.

Power Output

When thinking about purchasing a generator, the power output is a crucial consideration. The output should ideally be sufficient to supply the necessary amount of electricity. This will prevent you from having an overly weak or weak generator.

Both gasoline and propane can power the DuroMax XP12000EH. The generator can run on gasoline with a running power of 9500 watts and a surge power of 12000 watts. Propane, on the other hand, has 11400 operating watts and 9025 burst watts.

This generator is strong enough to run a heater, refrigerator, water reservoir, and other high-voltage power equipment, despite having a higher power output when using gasoline. Additionally, given the variety of appliances and bulbs that this whole house generator can power, the power output difference between gasoline and propane is essentially insignificant.

Fuel Tank Capacity

The size of the tank affects both the total runtime in a single tank and the weight of the generator. Due to this, a larger tank capacity results in a heavier generator but also more runtime. For instance, this generator’s propane tank can hold 40 gallons of fuel, and its gasoline tank 8.3 gallons. The battery can run for 8 hours on gasoline and 7 hours on propane.

Fuel Type

The freedom to use either gas or propane, each with distinct advantages, is doubled by dual fuel technology. For instance, gasoline has a smaller tank size than diesel, which means it requires less fuel to give a longer run time. As a result, it is more energy-efficient.

In contrast, propane is more cost-effective because of its lower pricing when compared to that gasoline. This indicates that using propane can help you cut your operating expenses. Moreover, unlike gasoline, propane does not deteriorate or lose its combustibility.

The fuel you choose will rely on you and your circumstances after looking at both possibilities. When you run out of gas, for instance, you may easily connect propane to power your house. Furthermore, the availability of gasoline can be compromised by natural calamities, necessitating a dual-fuel option.

You may run for a total of 16 hours without refueling if you fill both tanks and switch them out as needed, which is much longer than the typical run time. Alternatively, the DuroMax XP12000E would be a great option if you would prefer a gas-powered machine.

Fuel Type


The efficiency of a generator is based on power production and runtime. They make it simple to run high-voltage appliances, along with the DuroMax 457cc OHV engine. Because of its long run time, minimal fuel consumption, long engine life, and high power production, this portable dual-fuel generator is efficient.

Security Options

A power generator like this XP12000EH 12000-watt unit must have safety features in order to operate. This happens because generators release toxic gases and particles, like Carbon Monoxide, which is responsible for hundreds of fatalities each year. Similar to how negligence can lead to electrical shocks and even death.

In order to guarantee that the generator pollutants are below the acceptable range, DuroMax has received certification from both the EPA and CARB. To ensure your safety and the safety of the environment, the producers also employ cutting-edge technologies.

DuroMAx also uses a safety measure known as a GFCI (Ground Fault Circuit Interrupter). The GFCI protection of the household outlets makes sure that you are shielded from any mishaps brought on by faulty ground. The circuit breaker also proves useful.

Noiseless Performance

When building their models, DuroMax Power takes into consideration that nobody enjoys a noisy generator. Hence, the DuroMax XP12000EH has an enlarged muffler installed to reduce the noise level to 72 dB, which is somewhat louder than a vacuum cleaner. But, given how strong the engine is, this is to be anticipated. You won’t likely hear the noise when inside your home because, as I said earlier, it is best to place your lightweight dual-fuel generator far away from a building.

The convenience of the control panel

The fully equipped power panel of the DuroMax XP12000EH has a tonne of convenience features that make using this generator simple. Among these are the voltmeter, idle control, individual circuit breaker, and low oil level alarm.

The convenience of the control panel

MX2 Technology

The MX2 technology switch guarantees that each outlet will provide its maximum amount of power. Also, especially when using RVs, you can use a 120V or 240V outlet.

Electrical Outlets

Four different types of power outlets are available on the fully loaded power panel of the DuroMax XP12000eEH portable dual fuel generator. There are two 120V GCFI outlets for home usage. There is a 120V 30A twist lock and a 240V 50A heavy-duty power outlet. A switchable 120V/240V alternate outlet is also provided.

A generator must have the option of having multiple power outlets. As a result, you have the freedom to select an outlet when using heavy-duty equipment or appliances like a refrigerator or home air conditioner.

Electrical Start

The electrical generator starts using a 3-point engine switch key. You can also use a recoil starter, particularly in an emergency.


The DuroMaxXP12000EH boasts never-flat wheels and folding grips. They facilitate portability. Even with the wheels on, you shouldn’t frequently lift this generator because of its weight.


Oil Level Warning

You can keep account of how much petrol is still in the tanks thanks to the oil level alert. You can fill up the tanks as necessary in this manner.


Due to its lengthy engine life, this portable dual-fuel generator is exceptionally sturdy. Its sturdy metal structure also guarantees that it can survive challenging or severe circumstances. The generator is shielded from harm by an oil shutdown function that stops it from operating with insufficient oil. The sure arrest also shields the engine from voltage spikes to prolong engine life.
