Operating Instructions
Charging Your Devices
The charger intelligently distributes power based on the connected devices. For optimal charging, refer to the following guidelines:
- Single Device Charging: When only one device is connected to either USB-C port (Type-C1 or Type-C2), it can receive up to 100W of power.
- Multiple Device Charging: Power output will be dynamically allocated across all connected ports. For example, connecting a laptop to a USB-C port and a phone to a USB-A port will adjust the power delivery to each device accordingly.
