The temperature rise of mobile phone charger is related to the load of the charger. During the charging process, the output current is relatively large, the temperature of the charger will be higher, but it will not reach the hot temperature. After charging, even if the phone is still connected to the charger, the battery charging circuit is also automatically cut off, the charger output current is small, so the temperature increase is not obvious.
