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...Read more -
Why is the charger so hot when charging?
When charging the mobile phone, we often encounter the problem of the phone burning. In fact, the phone burning is related to the current intensity and environment of the phone charging. The higher the current, the faster the phone will charge. This often leads to the serious phone burning.Beside...Read more -
