Power adapter is an external power source used to convert AC grid voltage into a fixed, single low-voltage DC or low-voltage AC output voltage. It is widely used in various electrical products, especially information technology equipment, telecommunications terminal equipment and audio and video equipment, for example. : Laptops, tablets, mobile phones, multimedia players, LCD monitors, etc.

At present, China's power adapter standards mainly include GB4943.1-2011 "Information Technology Equipment Security Part 1: General Requirements" and GB8898-2011 "Audio, Video and Similar Electronic Equipment Safety Requirements". GB 9254-2008 "Radio Disturbance Limits and Measurement Methods for Information Technology Equipment", GB 13837-2003 "Limitations and Measurement Methods for Radio Disturbance Characteristics of Sound and Television Broadcast Receivers and Related Equipment", etc.

According to relevant standards, the State and relevant quality inspection departments have carried out supervision and spot checks on power adapter products from 2003 to 2012. The products have been covered with power adapters for information technology equipment, power adapters for telecom terminal products, and audio and video products. Use a power adapter. The main problems found in the spot checks are in the marking and instructions, plug type and size, wiring, connection and power supply, power resistance, conducted disturbance, radiation disturbance and so on.

Consumers can hardly distinguish their quality when purchasing a power adapter, but you can pay attention to the following points:

1. Preferred products that have been certified by “CCC”. If possible, check the authenticity and validity of their certificates on relevant websites.

2. Check the identity of the power adapter. Qualified products must contain information such as the rated input voltage or rated voltage range, the nature of the power supply, safety instructions, etc. Consumers should not purchase power adapter products with full foreign language identification.

3. Select the power adapter that matches the machine. Before purchasing the power adapter, you need to know the basic information such as the electrical parameters of the whole machine used with it, and the output voltage must be consistent with the rated voltage of the whole machine.

4. Check the plug and interface of the power adapter. Loose interface will make the current received by the whole machine unstable, and it may form a large instantaneous current, which will cause damage to the whole machine. If the interface is too tight, it will not be easy to insert or remove the interface.
