USB Inductive Charger Pins 2 & 3.

USB Inductive Charger Pins 2 & 3.

My little dog found the 5’ charging cord hanging off the table as something to chew on. Now it’s 3’ long. I simply put another USB connector on the end. What seemed odd to me was wires on pin 2 on & 3 of the connector. These pins are or - and + data. Pin 1 is Vcc & pin 4 is found.
