1. Reasons for high voltage and current

The short circuit and burning of the mobile phone charger may also be caused by the use of sockets with too high voltage or excessive external current. If the external current is too large, it will sometimes cause the output short circuit or input short circuit of the power supply overcurrent protection. Therefore, everyone should use the appropriate voltage socket for charging when charging.

2. Buy original charger

The necessity of buying original chargers and using original model mobile phone chargers. In a mobile phone store, the owner brought out a mobile phone charger with no brand, no certification, and no instructions for use. When the reporter questioned its safety performance, the owner simply said, "If you are afraid of an accident, you should buy the original one. There must be a reason for cheap things."

3. You must choose 3C certified products

As we know, "3C" is a unified mark used by the state for mandatory product certification. The certified power adapter meets the requirements of the national mandatory standards in terms of electrical safety and electromagnetic compatibility. This type of charger uses sufficient materials, mature technology, and has multiple protections such as overcurrent, overvoltage, short circuit, and overtemperature.

At the same time, in the process of use, such chargers have high charging efficiency and are safe and secure. The authenticity of the "3C" logo can be checked on the CNCA website. This avoids the possibility of buying fake chargers.

What methods can effectively avoid dangers such as short circuit of the charger? As long as the above points are followed, I believe that everyone can avoid these dangerous situations to a large extent. In addition, we should also remind everyone to follow these safety principles when purchasing chargers in the later stage and when using them, so that many dangers can definitely be avoided.
