Using USB-C (Thunderbolt ) Charging Function
You can connect the USB-C device to charge a notebook PC battery or an external device, and the
operation mode is automatically selected depending the charge settings of the connected device.
To charge a notebook PC battery, the external device (USB PD Charger, notebook PC, etc.) should
support USB Power Delivery 10 W (5 V / 2 A) or higher profile.
The external devices that use the USB-C port support 10 W (5 V / 2 A) and 15 W (5 V / 3 A).
A USB device compatible with USB PD (Power Delivery) supports charging at 15 W (5 V / 3 A),
whereas a regular USB device supports charging at 10 W (5 V / 2 A).
USB PD batteries cannot be charged using the USB-C port of the notebook PC.
Always-On Charging is supported only with USB-C ports, but not with the regular USB ports.
If you connect an adapter with a lower output than the rated adapter, it may take more time to
charge the notebook PC.
