There are two kinds of Android charging ports, one is v2.0 socket, and the other is the latest Type-c socket. The advantages of Type-C plug are slimmer design, faster transmission speed and stronger power transmission, and the plug is symmetrical, so don't be afraid to plug it backwards. Charger This equipment adopts high frequency power supply technology, intelligent dynamic adjustment charging technology and power electronic semiconductor devices to convert constant voltage and constant frequency alternating current into direct current. Generally composed of flexible printed circuit board and electronic components. According to the working frequency of the designed circuit, it can be divided into power frequency machine and high frequency machine, which are widely used in various metropolises, especially in the field of life, and are widely used in common appliances such as mobile phones and cameras.
