A handle is mounted on the other end of an extension with internal resistive heating element wires passing from the heating element to an internal circuit board with a microcontroller. A rocker switch is mounted on the handle connected to the circuit board. An LED is mounted to the handle connected to the circuit board. An external electrical cord connected to the circuit board and extending out of the handle with a positive battery post clamp and a negative battery post clamp is adaptable to be connected to a 12 volt battery.
