Using the PC
Using USB-C™ 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 AC adapter while the notebook PC is being used to charge an external device, it
may take more time to charge the notebook PC.
TIP
The charging status of the external device being charged is not displayed on the notebook PC.
If you connected a smartphone, you should select "Charge mobile phone" on the smartphone
screen to charge the phone battery.
CAUTION
If the power consumption of the notebook PC is larger than the power supply
from the external device, the battery may be consumed gradually.
