3. Operating Instructions
Once installed and powered, the charger is ready for use:
- Attaching Your Phone: Simply place your MagSafe-compatible iPhone (12 series or newer) directly onto the magnetic charging surface. The strong magnets will securely hold your phone in place. For other wirelessly charged phones without MagSafe, attach a metal ring (not included) to your phone or case to enable magnetic attachment.
- Wireless Charging: The charger will automatically begin 15W wireless charging upon phone attachment, indicated by your phone's charging icon.
- Retractable Cable Usage: To use the built-in Type-C cable for wired charging or data transfer, gently pull the cable out to the desired length (up to 25.59 inches/65 cm). To retract, gently pull the cable approximately 1 cm further, and it will automatically retract into the unit.
- Adjusting Viewing Angle: The charger features a 360-degree rotation capability. Adjust your phone's position horizontally or vertically for optimal viewing while driving.
