This wireless charger does not feature MagSafe-style magnetic alignment, and therefore is not able to charge the iPhone 12 series magnetically. Do not use Apple’s 5V / 1A stock charger or a computer’s USB port to power your wireless charger. Place your phone on the center of the PowerWave Stand to ensure stable charging.
