    Product Description

    The Scosche MagicMount Pro Charge5 Qi wireless mounting charger can be secured to your dashboard, window or any flat (slightly textured) surface with the reusable StickGrip suction cup base. Wirelessly charge any Qi-enabled device with up to 10-Watts of charging power without having to plug a charging cable directly into the device. The foreign object detection makes sure that charging only activates when nothing is obstructing that area (such as metal objects). Perfect for use with Qi enabled Smartphone devices and the iPhone 12, 13 or later with a MagSafe (without the need to use a MagicPlate) to secure the phone to the mount and wirelessly charge it. The extra powerful N50 neodymium magnets are 30% stronger than the original MagicMount to hold your mobile phone device securely in place even on the bumpiest roads and are still 100% safe for all modern smartphones. The low-profile mount safely attaches to your dashboard using the StickGrip suction cup base and can adhere to windshields, windows, kitchen countertops and all other non-porous surfaces. The easy install and dismantling allow you to take it anywhere you need your phone and mount most. NOTE: The Apple MagSafe is not included.
