The power adapter is also called an external power supply. It is a power supply voltage conversion device for small portable electronic devices and electronic appliances. It is commonly found in small electronic products such as mobile phones, liquid crystal displays, and notebook computers. The power adapter has a wide range of applications, not only on the mobile device side, but also in other fields. But if the power adapter wants to apply for CE certification, generally need to do the low voltage directive LVD and electromagnetic compatibility directive EMC, ERP, RoHS, etc. in the CE certification.

Power adapter CE certification processing standards

◆ EN 62368-1: Audio/video, information and communication technology equipment, safety requirements (adapter standards for TV, audio and other audio and video products)
