The power source can be battery, USB-C adapter and USB-C power bank on NB. User
may plug-in USB-C power bank and USB-C adapter together on host. In normal design,
host will choose the power source from USB-C adapter and charge the USB-C bank
and battery. But users may want to have capability to choose the power source. User
may want to choose power source from USB-C power bank because the output
capacity of power bank is higher. The system can have better performance with higher
capacity power source. We provide a Smart USB-C Power Source Control(SUPSC). It
will consider the system requirement and then help user to choose the power source.
Users can choose the power source by their request.
