Operating Instructions
The Anker 20W 2-Port USB-C Charger is designed for simple plug-and-play operation. Ensure your device is compatible with the charger's output specifications.

Simultaneous Dual Port Charging
When both the USB-C and USB-A ports are used simultaneously, the total power output of 20W is intelligently distributed between the two ports. This ensures both devices receive optimal charging power without exceeding the charger's total capacity.
- USB-C Port Only: Up to 20W
- USB-A Port Only: Up to 18W
- USB-C + USB-A Simultaneously: Total 15W shared (e.g., 7.5W per port)

It shows that when one port is used, the USB-C port can deliver up to 20W and the USB-A port up to 18W. When both ports are used concurrently, the total output is shared, typically 15W total (e.g., 7.5W per port).
