The supporting platform adopts a stepped design, which can effectively prevent the mobile phone from sliding down. The back of the wireless charger is equipped with an LED indicator and a USB-C input interface. When wireless charging is in progress, the LED indicator lights up green. Seen from the side, the body has a certain inclination, and the phone will not tip over during wireless charging. The junction of the two triangles looks fragile, but in fact, the bottom is supported by a metal plate, which is very strong. The metal plate is provided with an air inlet window and is pasted with a non-slip rubber pad.
