Recommendations and Notes
The Z230 USB charging port is recommended for portable devices supporting battery charging. It is a safe and eicient
charging solution, providing more current, and better over-current protection than a general USB port. Portable devices
are able to talk to the on-board charger and select a suitable charging mode and current based on real application needs
through a common communication protocol.
