When we are charging, the charger will heat up. This is a normal phenomenon that part of the electric energy of the charger is converted into electric energy during the charging process. But if the temperature of the charger is too high and exceeds a certain safety standard, then it is likely to be dangerous. What is the safe temperature of the charger? Charger manufacturer, here to tell you.
First, let me tell you about the general temperature resistance of the various parts of the mobile phone. First of all, the temperature resistance of the charger's plastic shell is generally about 110 degrees, the circuit board is about 130 degrees, the patch is more than 150 degrees, and the plug-in is about 100 degrees. This means that if the temperature of the charger exceeds 100 degrees, it will melt or burn.
China's 3C safety certification stipulates that in terms of the safe use of chargers, there are two certification temperatures that can be used as specifications. The surface temperature of the charger cannot be greater than 70 degrees, and the internal temperature of the charger cannot be greater than 90 degrees. Therefore, the charger products that generally pass the 3C safety certification are generally within a safe range when working.
In addition, some high-end power products will use V0 grade PC fire-retardant materials as the shell material, which can effectively prevent the charger from burning due to excessive temperature. The charger manufacturer reminds you to use safety-certified chargers correctly to make charging safer
