1. Setup Instructions
- Connect to Power: Connect the USB-C end of the charging cable to the magnetic wireless charging pad.
- Choose Adapter:
- For USB-C power adapters, connect the USB-C end of the cable directly to a 15W/20W or higher Power Delivery (PD) wall adapter (not included).
- For USB-A power adapters, attach the provided USB-A adapter to the USB-C end of the cable, then connect it to a compatible USB-A wall adapter (not included).
Note: A 15W/20W or higher PD adapter is required to achieve maximum 15W fast charging speed. Using an adapter below 10W may result in slower charging performance.
- Power On: Plug the wall adapter into a power outlet. The charger's LED indicator will pulse blue three times to confirm power connection.
