  • How to solve the problem of mobile phone charging heating

    As we mentioned earlier, there are many electronic components in the charger. The principle is to convert 220 V AC power into 5 V DC power through the rectifier bridge, and then charge the mobile phone through the data line. In this process, if the input 220 V AC power breaks through the rectifie...
