To take advantage of the 15W charging power, the charger needs to be connected with the supplied cable and to a wall adapter of at least 20W. The base is built with a USB-C input and output as well as a 5W induction output to charge an earbuds case (AirPods type). The charger comes with a magnetic sticker to ensure compatibility with all phones (device must be induction compatible). If the phone does not have MagSafe technology (starting iPhone 12), the sticker can be attached to the back of the phone to make it compatible with the magnetic holder. Delivered with a charging cable made from recycled PET. Charger size: 7 x 8 x 12.5 cm. Packed in a gift box (11 x 10 x 12.5) with magnetic closure. Includes 3 years warranty.
