In addition, it runs on gasoline and propane, which gives you flexibility and convenience when gasoline is difficult to access, or you don't want to keep refueling regularly.

With this portable dual fuel generator, you can run your home appliances, such as the refrigerator, home A/C and other heavy-duty power tools. The heavy-duty all-metal construction also makes this generator suitable for work sites. In addition, the extended runtime is a plus, especially if you live in an area with long power outages.

DuroMax XP12000EH Dual Fuel Portable Generator Review

This generator is guaranteed to offer you effectiveness, flexibility, convenience and durability. So without further ado, let's look at the features that make the DuroMax XP12000EH a workhorse.

1. Power Output

The power output is a very critical factor when considering buying a generator. Ideally, you want to ensure that the output meets your power needs. This way, you don't end up with less power or a generator that is too powerful.

The DuroMax XP12000EH is powered by either gasoline or propane. The generator has a surge or starting power of 12000 watts and a running power of 9500 watts on gasoline. On the other hand, propane has 9025 surge watts and 11400 running watts.

Although the power output is higher when using gasoline, this generator is powerful enough for furnace, freezer, sump pump, and other high amperage power tools. In addition, the power output difference on gasoline and propane is almost negligible considering the number of appliances plus lighting that this backup generator can run.

2. Tank size

The tank size determines the overall runtime in a single tank as well as the total weight of the generator. For this reason, a large tank capacity means more runtime but also a heavier generator. For example, this generator has a gasoline tank capacity of 8.3 gallons, while the propane tank capacity is 40 gallons. Additionally, the run time is 8 hours on gasoline and 7 hours on propane.

3. Fuel Type

Dual fuel technology doubles the flexibility to use gasoline or propane, each having its own benefits. For example, gasoline is more energy-efficient since it has a lesser tank size meaning it uses less fuel to provide a longer run time.

On the other hand, propane is more economical as it has lower prices compared to gasoline prices. This means that you are able to lower your running costs when using propane. In addition, unlike gasoline, propane does not lose combustibility or degrade.

Having looked at both options, the fuel choice will depend on you and your situation. For instance, you can easily connect propane to power your home once you're out of gasoline. Additionally, natural disasters may make it difficult to access gasoline, needing a dual-fuel option.

Fueling both tanks and switching out when necessary gives you a total run time of 16 hours before refueling, which is way above the standard run time. However, if you would rather have a gas-powered model, the DuroMax XP12000E would be an excellent choice.

4. Efficiency

A generator's efficiency is determined by the power output and the run time. These, combined with the DuroMax 457cc OHV engine, ensure that powering high voltage appliances is made easy. In turn, this makes this portable dual fuel generator an efficient one as it boasts an extended run time, low fuel consumption, long engine life and high power output.

5. Safety Features

Safety features are mandatory when operating a power generator like this XP12000EH 12000 watt model. This is because generators produce harmful gases and particles, such as Carbon Monoxide, which accounts for hundreds of deaths yearly. Similarly, carelessness could result in electric shock and even death.

DuroMax has CARB(California Air Resources Board) and EPA(Environmental Protection Agency) certifications to ensure that the generator emissions are below standard. In addition, the manufacturers also use advanced technology to implement safety to you and the environment.

The GFCI(Ground Fault Circuit Interrupter) is another safety feature implemented by DuroMAx. This ensures that you are protected from any incidents resulting from the faulty ground since the household outlets are GFCI protected. In addition, the circuit breaker comes in handy during emergencies.

6. Quiet Operation

DuroMax Power keeps in mind that no one likes a noisy generator when manufacturing their models. Therefore, the DuroMax XP12000EH has an oversized muffler installed that brings down the noise level to 72 dB(decibels), a bit louder than a vacuum cleaner. However, this is to be expected considering how powerful the engine is. Again, considering that it is advisable to put your portable dual fuel generator a considerable distance from a building, you are not likely to hear the noise while in your house.

7. Control Panel Convenience

The DuroMax XP12000EH has many convenience features on the fully-featured power panel that makes operating this generator a breeze. These include the voltmeter, idle control, individual circuit breaker and a low oil level alert. Let us further look at each feature.

i). MX2 Technology

The MX2 technology switch ensures you get maximum power output from each receptacle. In addition, you can use either a 120V or 240V receptacle, especially when using RVs.

ii). Power Outlets

The DuroMax XP12000eEH portable dual fuel generator has four types of power outlets on the fully loaded power panel. There are 2 household GCFI outlets, each 120V. There is a 240V 50A power outlet for heavy-duty use and a 120V 30A twist lock. In addition, there is a changeable 120V/240V alternative outlet.

The choice of having different power outlets is essential in a generator. In turn, this gives you the flexibility to choose an outlet when powering machinery like a refrigerator or home air conditioner or heavy-duty equipment.

iii). Electric Start

There is a 3-point engine switch key that starts the generator electrically. Alternatively, you can use a recoil started, especially during an emergency.

iv). Oil Level Alert

The oil level alert helps you track how much fuel is left in the tanks. This way, you can refill the tanks when need be.

v). Additional Accessories

This portable dual fuel generator comes with additional accessories that contribute to its effectiveness. These include a spark plug wrench, oil funnel, toolset, an owner's manual and charging cables.

8. Portability

The DuroMaxXP12000EH has foldable handles and never-flat wheels. These help to make it portable. However, you don't want to lift this generator often, even when the wheels are on, as it is heavy-weight.

9. Durability and Maintenence

This portable dual fuel generator is very durable as it has a long engine life. The durable metal construction also ensures that it can withstand tough or harsh conditions. An oil shutdown feature prevents the generator from running on low oil, protecting it from damage. In addition, the sure arrest protects the engine from power surges to ensure a longer engine life.
