10 Best Dual Fuel Generators in 2019

Dual fuel generators are incredibly useful pieces of kit. They will provide your home with back-up power should any emergency, electrical shortage or natural disaster occur. They rely, as their name suggests, on two forms of fuel. Both gasoline and propane are used to generate electricity within dual fuel generators. Relying on two forms of fuel makes dual fuel generators perform better and provide power for longer than their standard counterparts. Using two forms of fuel also makes them cheaper to run.

Although gas is readily available, it can be quite expensive and does have a few other disadvantages. Propane is a cheaper, cleaner and quieter fuel. This combination of both gasoline and propane makes dual fuel generators better, more reliable and convenient devices for so many different uses.

Buyer’s Guide To Dual Fuel Generators

Dual fuel generators are brilliant devices that can be used within the home, at work or even when traveling. They operate in a similar manner to regular generators by creating electricity from another fuel source – which is why they are suitable for emergencies. However, dual fuel generators use both gasoline and propane. As they rely on both gasoline and propane, dual fuel generators are versatile, cheaper to run and actually provide better power than their standard counterparts.

Dual fuel generators are portable devices that can be used when there is no other power source. Many households are seeking to purchase a dual fuel generator to keep on hand for emergencies such as natural disasters, power cuts or other power shortage issues. Depending on the size and wattage power, these generators can be used to fuel your home and essential appliances. These ensure that you can maintain some normality, as well as keeping your family comfortable and safe, during an emergency situation.

Why Should I Get A Dual Fuel Generator?

Dual fuel generators may seem like complicated devices, meaning many homeowners will ignore them every time they shop. However, they are actually quite simple, easy to use and the reasons behind investing in one follow the same pattern. These devices are a brilliant and often essential investment for many homeowners. If you live in a stormy area or simply want to be prepared for any kind of emergency, then having a portable dual fuel generator around the home can make all the difference.

The reason dual fuel generators are preferred over their standard counterparts is the fact that they rely on both propane and gasoline to provide a longer run time of power. Having a longer run time is essential when preparing for an emergency or even if you need a generator for your outdoor adventures, such as camping. As dual fuel generators have two power sources, they can be used to deliver more power for longer as they switch between the two. Dual fuel generators are also cheaper to run than their standard counterparts.

Although gasoline is a readily available fuel source, it can be quite expensive to use and has a range of other disadvantages, including their effect on the environment. Propane, however, is cheaper and can be a great alternative fuel source for your generator. Dual fuel generators are a brilliant investment due to their range of other additional benefits. These benefits include:

Versatility

As dual fuel generators can generate electricity using both gasoline and propane, they are incredibly versatile devices. Having an option of fuel source ensures that these generators can be used anywhere – making them suitable for camping vacations or isolated homes – as well as giving those with varying budgets more options.

Both gasoline and propane are easy to obtain, and both should be available in most garages or hardware stores. Propane is cheaper to run and also is more likely to be easier to store than gasoline, due to the storage container it comes in. Being able to choose between gasoline and propane, as well as being able to use both at the same time, makes dual fuel generators suitable for a wide range of people, locations and purposes.

Effective And Uninterrupted Power

As dual fuel generators rely on both gasoline and propane, they can deliver a much more efficient and effective power than their single fuel counterparts. They are cheaper to run as they rely on two forms of fuel, as well as being safer to use. Gasoline is suitable for cold weather climates as it is unlikely to ignite in these conditions. However, propane can easily flare up in cold climates making this fuel source more suitable for summer use. Choosing between either fuel source depending on the situation, weather or season makes dual fuel generators safer to use than their standard counterparts.

They can also be easily switched between gasoline or propane, even when in use, to give you total control and alter the power output to suit your appliance, technology or need. This reliance on both gasoline and propane makes dual fuel generators better for long-term use. This is perhaps one of the biggest advantages of these devices, as they can provide a longer run time of power than single fuel generators. This long-run time makes them suitable for a range of uses, including residential, commercial and professional use.

What Is The Difference Between Generators?

There are two kinds of generators, single fuel, and dual fuel.

  • Single Fuel Generators are a standard model that runs on one type of fuel. This is typically gasoline.
  • Dual Fuel Generators rely on both gasoline and propane to deliver a better, more efficient and longer run time of power. These generators are cheaper to run and can be used for more things than their standard counterparts.

What Is A Dual Fuel Generator?

A dual fuel generator is an electronic household device that uses propane and gasoline as fuel. They are devices that can power electronic devices in areas or circumstances where there is no other power source. As they rely on both gasoline and propane, they are cheaper to run than standard generators and can be used in more situations.

How Do Dual Fuel Generators Work?

Dual fuel generators operate the same way as single fuel generators, except they rely on both gasoline and propane to power. Generators convert mechanical energy that has been obtained from an external source, like gasoline or propane, into electrical energy. This electrical energy is then given as the output of these devices.

Dual fuel generators do not actually ‘create’ electricity, despite any previous beliefs. They instead rely on the mechanical energy supplied through propane or gasoline to force the movement of electrical charges that are present in their wires. This movement causes an electrical charge that can be used to power your appliances and technology during an emergency, natural disaster or when in the great outdoors.

When To Use A Dual Fuel Generator?

Dual fuel generators are devices that can provide electricity to power your household appliances, technology or other essential devices when there is no other power source. These kinds of generators rely on both gasoline and propane as fuel. You can switch between these two fuel sources depending on what needs to be powered, where you are and what you have left. Dual fuel generators are incredibly beneficial, versatile and convenient devices that can be used in both extreme or standard situations for power.

You can use a dual fuel generator when:

  • The power has run out in your area to keep your essential household appliances, like the fridge, working
  • During a camping trip to power a portable heater and charge your phone
  • In a natural disaster when there is no electricity anywhere
  • In your RV or another transport vehicle to power the air conditioning, heater or other electrical items
  • If you live in a remote area where the power is unreliable and may not be suitable for certain devices, appliances or technology.

Did You Know?

Dual fuel generators are more efficient, have longer run time and are cheaper to run than standard, single fuel devices.

Expert Tip

Propane is cheaper to run and may be easier to store due to their containers.
