Tri-Fuel Generator
As the name suggests, Tri fuel Generator can run on three different types of fuels viz Propane, Natural gas, and Gasoline. To switch between the fuels, just turn on the selector valve located above the low-pressure regulator
If you are looking for a portable generator that can run for longer days, then a generator with alternate fuel options is a great solution. These generators are suitable for areas with fluctuating fuel prices and inconsistent fuel availability. When natural gas is used, refueling is unnecessary. Propane is also another convenient option as it can be stored for longer periods of time and it is easier to find than gasoline during blackouts. Propane is a very clean-burning fuel that does not leave any damaging residue inside the engine. Using natural gas will increase the lifespan of the generator.
The most widely used fuel source is gasoline. But in these situations, you may not get sufficient gasoline. Hence a tri-fuel generator helps you run your appliances because these units have the facility to switch between different fuels.

Guidelines for purchasing a tri-fuel generator
Before purchasing a tri-fuel generator, you should consider all the important factors to avoid problems later. The following are some of the guidelines that help you to make a clearer decision.
Wattage and Engine
The Powerful engine of the generator should be protected under a iron sleeve. This is the main factor to be considered before buing a generator. The unit's engine does not need high potential as the engine have less fuel efficiency.
Next, you should calculate the wattages required to powerup the electronic devices. Along with the peak power, consider the rated power also
Remember that the starting power and the running power can differ according to the types of fuel used. Power output variation depends on the types of the fuel. So ensure which fuel is best to meet your essential demands.
Runtime and Fuel Tank Capacity
The size of the fuel tank is directly proportional to the runtime. So you have to choose the generator wisely. Moreover, the load applied, the efficiency and the type of fuel used are other factors by which the runtime can be affected.
If you going to run the generator using gasoline, you have to consider the fuel size. In case if propane is used, you have to purchase a tank separately.
Fuel Consumption
Fuel consumption is another main factor to be considered if you looking for a generator for your budget. Many generators require much fuel where some of the tri-fuel generators intake minimum fuel
Based on the applied load and the type of the fuel used, fuel consumption varies. But Gasoline is used less in other generators.
Starting time
Starting up a generator manually is difficult whereas it is easy to start a generator possessing a electric start button.
Power Outlets
The number of power outlets define how much appliances can be powered up during a blackout day. Choosing multiple power outlets is an advantage.
Safety Features
The stable power output is provided by the voltage regulation automatically. A sensor is used to detect when the low gets low. This helps in automatic shutting off the generator's engine.
