Question

how to make a battery fan

Answer 1

The basic components of an electric fan and method of assembly, are consistent whether you're building a tiny personal fan to run off an AA battery or a giant industrial fan powered by a series of car batteries. For this fan, we'll use a nine volt battery and a cooling fan from an electronic device. You can use any fan and battery, as long as the input voltage and current on the fan motor, match the output voltage and current of the battery.

Strip a quarter of an inch of wire from the ends of each of the wires connected to the snap connector and the fan.

Twist the exposed sections of the positive wires, which are typically red, around each other. Heat the wires with your soldering iron and apply solder over the joint to bind the wires.

Repeat step two for the negative wires. Cover both solder points with electrical tape so that no wire or solder is exposed.

Connect the nine volt battery to the snap connector and enjoy the cool breeze.
