The ac dc power adaptor China is a power supply conversion device for small portable electronic devices and electronic appliances, and is an indispensable power source for PCs and mobile devices. Today, let's answer some questions related to the ac dc power adaptor China.
Q: What should I do if sparks appear when the ac dc power adaptor China is plugged into the socket?
A: This spark is called an arc phenomenon. When the plug touches the metal contacts in the socket, there may be tiny sparks due to the small contact area at the moment of contact and the instantaneous flow of current when the plug is inserted. Even slight damage can be seen on the plug of the ac dc power adaptor China, this is normal, don't worry too much.
When the sparks are large or blackened traces are found on the socket, please stop using it. This situation may be caused by the aging of the socket, or insufficient clamping force of the internal copper sheet, or the socket has moisture, oxidation, etc. It is recommended to replace the socket.

Q: Why does the ac dc power adaptor China get hot during use?
A: Because the efficiency of the ac dc power adaptor China to convert energy cannot be 100%, there must be a part of the electric energy converted into heat to make the power adapter heat up. At this time, attention should be paid to the ventilation and heat dissipation of the ac dc power adaptor China.
However, when the ac dc power adaptor China is empty, there should not be a large amount of heat dissipation. If the ac dc power adaptor China still heats up severely without external equipment, or if the appearance is deformed during use, and there is a peculiar smell, stop using it immediately.
