Buying guide for dual fuel generator

Best dual fuel Generators are devices used to supply electrical power to appliances or machines. They convert mechanical energy into electrical energy. The mechanical energy is obtained from external sources such as engines powered by gasoline, liquid propane, natural gas, diesel, etc.

It is important to understand that the generators do not create electricity, but supply the mechanical energy that forces the movement of electrons or particles carrying the charge that we call electricity through the wires in the circuit.

Simplifying it further, let us compare the electrical charge to water. The water is there in a pipe or a reservoir. All we do is force the water to flow by applying mechanical force. This force is the push that sets the flow of water into motion. The mechanical force may be in the form of gravity or pedalling of the water wheel.
