Metal Patch Using Guide
QI Wireless Charing Metal Plate:
When using the magnetic phone mount, please stick the metal plate to the phone back.
The truck phone mount comes with a small round metal plate, specially designed for QI Wireless Charging.
Wireless charging mobile phones wirelessly charge in the middle of the charging pad, so leaving enough space above and below the charging pad to place a QI metal plate that won't interfere with charge.
