Introduction
This standard is formulated with a view to, on the premise of ensuring the safety and usability of products, enabling different types of mobile telecommunication terminal equipment to share the adapter with the same specification by specifying a unified port mode and technical requirements.
This standard defines the charging connection in a three-stage mode, i.e., power adapter, cable and mobile telecommunication terminal. Therefore, the application scope of this standard can be further expanded. For example, this standard can also be referenced for charging or power supply of portable or household small electronic equipment, so as to further reduce electronic waste, protect the environment, save resources and reduce the use cost.
