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 communication terminals to share the same specification of power adapter by specifying a unified port mode and technical requirements.
This standard defines the charging connection in a three-stage mode, i.e., AC-DC power adapter, cable and 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.
Technical requirements and test method for power adapter and charging/data port of mobile telecommunication terminal equipment
1 Scope
This standard specifies the technical requirements and testing method for charging/data ports, AC-DC power adapters and cables of mobile communication terminal equipment (hereinafter referred to as "terminals"), including the physical characteristics, electrical characteristics, safety characteristics, electromagnetic compatibility, environmental adaptability and identification involved.
This standard is applicable to terminals, AC-DC power adapters and their connecting cables using wired power supply, but not applicable to mobile terminals requiring special power supply and application, such as special mobile devices only used in enterprises and industries. This standard can also be referenced for the power supply or charging of other portable or household small electronic equipment.

4 Technical requirements
4.1 Overall connection
For the purpose of this standard, a three-stage mode of power supply connection is adopted, i.e., power adapter, cable and terminal (power device). The power adapter converts AC power supply into DC power supply and then outputs it through USB A socket. This part only serves as an AC-DC conversion adapter. On one end of the cable, USB A socket of the power adapter is matched with USB A plug. On the other end of the cable, power socket of the terminal is matched with such plug that shall be Micro-USB B, Mini-USB B or cylindrical plug. The power socket of the terminal shall be Micro-USB B/AB, Mini-USB B/Mini10pin or cylindrical socket. However, if the terminal is a device with OTG function, the power socket shall be of Micro-USB Type AB. Besides charging, Micro-USB B/AB or Mini-USB B/Mini10pin is also the data transmission port of the terminal. The overall connection is shown in Figure 1.

When USB A socket is used as the output port of the power adapter, the requirements are shown in Figure 3. VBUS is the positive pole of the output DC power supply, while GND is the negative pole (grounding) of the output DC power supply. D+ and D- shall be short connected inside the power adapter and isolated from other circuits, so that the terminal connected to them can identify that the connected device is a power adapter defined in this standard.
