When many friends buy China ac adapter, they may encounter the problem of getting hot, even so hot that they dare not handle it with their hands. What is going on? Is it normal? How to solve this problem? This article will answer the question for you. 
Why does China ac adapter get hot?
The conversion efficiency of China ac adapter cannot yet reach 100%. When China ac adapter converts the voltage, a part of the energy is lost. Except a small part is lost in the form of waves, most of it is dissipated in the form of heat. The higher the power of China ac adapter, the more energy is lost, and the more serious the heat will be.
As long as the temperature of China ac adapter is within the design range, that is to say, the temperature of China ac adapter is within the normal range, it is generally not dangerous!

How to solve the problem of China ac adapter overheating?
1. Create a good heat dissipation environment, and place China ac adapter in a place that is not exposed to sunlight and ventilated. It can be used for a long time at high temperature. If you must use it for a long time, you must pay attention to heat dissipation.
2. Put a narrow plastic block or metal block between the adapter and the desktop to speed up the heat dissipation of the adapter.
3. Always wipe China ac adapter with a dry cloth or paper towel to prevent dust from entering the adapter and reduce the heat dissipation performance of the adapter.
