What To Consider While Choosing A 12000 Watt Dual Fuel Generator

It would be best to have a 12000-watt dual fuel generator to provide power during outages and natural disasters. It is also a great investment for homeowners who want to reduce their electricity bills by running household appliances at night with frequent blackouts.

12000-watt dual fuel generators use gasoline and liquid propane gas (LPG) to generate energy for homes or other buildings where traditional electrical current is unavailable. 

The cost of running a 12000-watt dual fuel generator depends on the price of the LPG being used. If you are planning to purchase a 12000-watt dual fuel generator, then you should consider the following aspects:

Ignition Start Type

The ignition start type's importance depends upon the user's purposes for purchasing a 12000-watt dual fuel generator.

 An electric start would be necessary for a person who needs to use their generator in an area where they need to restart the unit several times throughout its use.

A manual start will work just as well for people who do not expect to need to restart their generator very often during its use. 

The main difference between these two types of generators is how one starts it up. Electric start is usually easier and faster than the manual start, and this is important, especially in cold weather.

Tank Capacity

The tank capacity of a generator is very important. It indicates how long the generator can run without being refueled. If you plan to use your generator continuously, you should choose one with a big fuel tank capacity.

Noise Level

Consider the noise decibels as you do not want to disturb your neighbors! If you plan on using a portable generator for a large load, be sure to check the decibel level of the unit before setting it up. 

 The lower the number of decibels, the quieter it is. Most 12000W dual fuel generators range between 68-76 decibels. 

Run Time On Full Tank Of Fuel

It is important to have a plan for refueling to maximize your generator running time. To determine how long the generator will run on a fuel tank, you must know the fuel capacity.

Great generators have a longer running time of about 8 hours and above.

Size Of Generator (Weight)

A generator's weight is an important factor to consider when determining which one you will purchase. Ordering a generator online is a critical decision and not something to be taken lightly.

If you take your generator with you to the job site, your best bet is a portable generator that weighs less than 220 pounds. This way, it is easier to move around without using a forklift or anything of that nature. 

 The size of the generator you need will depend on your expected power usage and the number of hours you plan to use it. Campers would require portable generators with no-flat tires.

Advanced Features

Does it have advanced features like automatic start, stop, or load control?

Efficient cooling; This is an advanced electronic temperature control (ETC) that provides efficient cooling by automatically adjusting fan speed in response to temperature. 

Most portable generators have an automatic low oil shutdown feature that prevents damage caused by running your unit when your oil level is too low. 

The inverter technology gives more power and less noise than others in its class so that it won't interrupt neighbors' peace or other people living nearby.


When choosing a 12000Watt dual fuel generator, it's important to pick one that comes with a longer warranty period. This way, if any complications arise, such as malfunctions, you can be sure to get the manufacturer's support.

The longer the warranty, the more confident you can be in the product. The last thing you want is to buy something that breaks down after a couple of years and ends up costing you even more!

Detailed Instruction Manual

Some generators come with really good instructions while others do not have any! If you are planning on buying a 12000-watt dual fuel generator, make sure that the product has an instruction manual included in the package. 

Instructions will help you understand how to use and maintain your generator properly. If you do not consider this, you can end up with a model that will be hard to handle and use. 


As you can see, not all 12000-watt dual fuel generators are the same. You now have the information you need to compare various high-quality generators and choose the best one for your needs.

We hope we have provided you with the information you need to make an informed buying decision regarding purchasing a 12000-watt dual fuel generator.
