Hi there, You can put a new USB Type A connector on there. They are arranged as the following (1) VCC (2) D- (3)D+ (4)GND. (optional but recommended: connect the cable shield to the connector shell of the new connector) The Data lines are bing used to see what type of charger it is. That also allows is to see how much current it can pull from the charger. I hope this has helped you.
