1, the mobile phone charger itself is designed to be relatively compact, easy to heat in the process of use, if the surrounding heat dissipation environment is not good, the heat generated is not easy to dissipate, easy to cause damage to the charger. Each electronic component has a safe operating temperature range, high temperature, hot and humid environment, component reliability will be greatly reduced, beyond this range may lead to component breakdown or failure, and eventually lead to damage to the charger.
2, when charging the mobile phone, the use is not the original charger, or the power output of the charger does not match the original charger, which is one of the reasons why many mobile phone instructions require the use of the original charger for charging. For example, using a charger with an output of only 0.5A to charge a mobile phone with a demand of 1A is not only slow in charging, but also easy to damage the charger due to long-term overload.
3, the use of no 3C certification charger to charge the phone, or the use of cheap, no quality assurance of the cottage charger to charge the phone. Charger problems are more from its own quality problems, \"cheap\" copycat charger internal often have serious design defects, coupled with corners, protective devices may not pass or lack of protection circuit, can not guarantee the stability of charging current, low safety and reliability is a common problem of these products.
