Magnetic Module Keeps Your Phone Charged, Secure and Ready to Use

The magnetic charging pad is compatible with all smartphones and other devices that support wireless charging. It also works with MagSafe-compatible smartphones (including iPhone 12 and later) to prevent the phone from being jostled off the pad and disconnected while charging. 

Adjustable Stand Gives You More Flexibility Over Charging

You can charge your phone while it lays flat on the charging pad, or you can use the adjustable kickstand for flexible placement during charging. You can place the phone vertically to read notifications and messages while it charges or horizontally to stream video.
