Key Features

1) Size and Power Output

To ensure that you make the most optimal decision, it is important to understand your power needs. This will prevent you from selecting a generator that is either too powerful or not powerful enough, which could lead to unfavorable outcomes. Therefore, it is crucial to accurately calculate the total power output required for your specific needs.

Experts advise purchasing a portable generator with 20% more pow erthan what has been calculated. This additional power buffer can be extremely beneficial in emergencies. By following this recommendation and having a clear understanding of your necessary power output, you can make a wise and practical choice when choosing a generator.

This particular dual-fuel generator can generate up to 12000 peak watts and 9500 rated watts when using gasoline. However, its power output is slightly reduced when operating on propane, producing a maximum of 11400 surge watts and 9025 running watts on this alternative fuel source.

This high-powered generator is capable of running most of your equipment, making it perfect for both home and job site use. It can handle even heavy-duty power tools and essential appliances with ease. In addition to powering various household appliances such as refrigerators, freezers, sump pumps, and furnaces, this backup generator can also support an additional window air conditioner.

The tank size determines how long the generator can run on a single tank, but it also contributes to its overall weight. A larger tank provides longer runtime but also increases the generator’s weight.

The DuroMax XP12000EH boasts an impressive fuel tank capacity of 8.3 gallons, ensuring long-lasting power for all your needs. It comes with a suggested propane tank size of 40 lbs, making it convenient and optimal for use.

2) Design

At 224 pounds, this 12000W generator is not lightweight, so please refrain from attempting to lift it. However, the good news is that it has an ergonomic handle and wheels for easier mobility. Unfortunately, some users have expressed dissatisfaction with the wheels themselves as a concern.

3) Fuel Type

The effectiveness of a generator relies on its power production and duration of operation with the given fuel quantity. An effective generator provides cost savings over its entire lifespan. Efficiency is achieved through reduced fuel consumption, increased power output, and extended engine longevity in the case of DuroMax XP12000EH.

This dependable dual-fuel option boasts an impressive runtime with 8 hours using gasoline and 7 hours using propane at half load. Furthermore, this generator has an idle control feature that automatically reduces unused RPMs.

This not only conserves fuel but also minimizes noise levels during idle periods. Choose the DuroMax XP12000EH for robust performance and economic benefits throughout its lifetime. Dual-fuel technology in generators proves to be highly beneficial during extended power outages and unpredictable events like natural disasters.

The ability to switch between fuel sources is particularly advantageous in challenging circumstances. If gasoline runs out, one can easily switch to using propane as a backup option, ensuring an uninterrupted power supply.

Furthermore, given the lower cost of propane compared to gasoline, this feature also offers practicality when it comes to managing expenses. This convenience is especially useful for those reluctant or unable to obtain additional gasoline during a crisis.

An excellent example of a generator with this capability is the DuroMax XP12000EH, which allows for both gasoline and propane usage as fuel sources.

4) Quiet Operating Generator

Generators that create excessive noise can cause disturbances for those living nearby. In the event of a power outage or emergency, many individuals rely on portable generators. However, imagine being the owner of the loudest generator in your neighborhood.

The DuroMax XP12000EH has a noise level of 72DB, which is comparable to the sound of a running vacuum cleaner. While it’s understandable that a powerful generator may produce some noise, it’s important to be considerate and strategically place it further away from residential areas.

By doing so, you can still reap the benefits of reliable power without causing unnecessary disruptions for your neighbors.

5) MX2 Technology and Power Outlets

This function guarantees optimal power output for every receptacle, allowing you to utilize both 120V and 240V outlets simultaneously. It is especially convenient for RV owners. The DuroMax 12000 watt generator is equipped with various outlets to ensure optimal compatibility. These include two 120V GFCI household outlets, one 120V twist-lock outlet, one 240V 30A outlet, and another 240V 50A outlet.

Additionally, it is designed with convenient DC charging ports for external battery charging purposes. This wide range of outlets makes this generator suitable for diverse power needs and allows easy connection to different devices or appliances.

With its comprehensive selection of outlets, the DuroMax generator provides versatility and convenience in powering your electrical equipment.

6) Durability

The DuroMax XP12000EH is a robust generator with a sturdy engine that can endure harsh environments. Its metal construction adds to its durability. Moreover, the generator features a low oil shutdown function that safeguards it from potential damage caused by operating on insufficient oil levels.

In addition, surge arrest technology protects the engine against power surges and helps prolong its life span. For ease of mobility, this hybrid generator comes equipped with never-flat wheels and foldable handles. However, due to its considerable weight, even with these features, frequent relocation may prove challenging.

7) Safety Features

Proper safety precautions must be taken when operating a powerful generator like the DuroMax XP12000EH. All portable generators emit harmful gases and particles, including Carbon Monoxide.

Negligence or lack of caution can lead to dangerous incidents such as electric shocks, and Carbon Monoxide has been dubbed the silent killer due to its role in hundreds of deaths every year. To ensure safety, generator manufacturers have implemented various advanced technologies. The Environmental Protection Agency (EPA) and California Air Resource Board (CARB) have established emissions guidelines for generators, with compliant ones adhering to emission levels below these standards.
