The charger uses a switching power supply, which has a rectifier diode and a small ballast, when you charge the current through the two objects increases, it will heat, the charger is a closed body, the air inside will be heated, so the charger shell will heat. However, the general fever will not reach the degree of hot, if the temperature of the charger has reached the point of hot should be the first time to unplug the charger, to avoid damage to the mobile phone hardware, to prevent the occurrence of personal injury accidents caused by hardware failure or improper use. In order to avoid the heating caused by the failure of the charger and the aging of the battery, the following points should be paid attention to during the use of the charger: 1. When charging in a cool environment, do not play with the mobile phone when charging. Do not overcharge.
2, do not use the mobile phone when charging, if conditions are best to shut down charging, it is best to use the original charger, in the case of damage to the original charger, check the type of battery used, capacity, nominal voltage, find the charging head, and then charge the mobile phone.
Because there is a process that quickly converts the electricity into the phone's battery, there is heat.
Because during the charging process, part of the electrical energy is converted into heat and emitted
