Pin Configuration of Power Bank Module T6845-C
The pin configuration of the module is pretty simple and can be easily understood by the following image.
The image shows the two USB port connectors, battery connector points (Battery-, Battery+), and the charge controller IC used. The module has two USB ports; USB A and Micro B USB port. USB A is for the output which can be connected to a device that is to be charge (discharging USC Output), whereas the Micro B USB port can be connected to a 5V adapter to charge the batteries (Charging USB Input).
Note: When the batteries are charging, the red LED flashes, and when the batteries are fully charged red LED glows for a long time.
