[0038] Specifically, when the first interface unit 100 or the second interface unit 120, i.e., the C male connector, is connected to an iPhone, the USB core unit 170 communicates with the iPhone to obtain a set of system keys. The chip U4 sends this set of keys to the authentication database, which returns a set of calculated decryption keys. The chip U4 then sends this key back to the iPhone. The iPhone compares the received key with its own key. If they are consistent, it returns the authentication pass information and ends the authentication process. Afterwards, the iPhone can be charged through the second main control module, the analog switch unit, the charging switch unit, and the first main control module.

The analog switch unit 150 can also be adjusted to enable data transmission between the mobile phone and the tablet. Alternatively, the charging switch unit 130 can be triggered by the analog switch unit 150 to charge the end with a higher battery level to the end with a lower battery level. Furthermore, data transmission can be achieved while charging. To check the battery level or when necessary, the button unit can be pressed or the external device (off-line, i.e., without external power input) can be left displayed with the battery percentage, thereby intuitively providing the user with a detailed understanding of the current battery level of the external device, the charging speed, the data transmission speed, etc. In other words, it is possible to realize the display of charging status information of a single external device, the display of charging status information of two external devices (you can press the button unit first to display the power or power of the external device connected to the first interface unit 100, and the power or power of the external device connected to the second interface unit 120 will be displayed after 10s), data transmission while charging between two external devices, and power transfer and data transmission between two devices. In addition, during data transmission, pressing the button unit can also display the percentage of data transmission rate, wherein the displayed power can change from low power to full power, that is, the corresponding displayed number is red, yellow to green, and data transmission can be similar to the power display color process. The power display can change from high power to low power to achieve PD fast charging, thereby expanding the application range of the data display connector. Among them, the charging switch unit 130 can adjust the input voltage of the first interface unit 100 and the second interface unit 120, that is, adjust the voltage level to achieve PD charging mode, and the power processing unit 110 can provide a stable power supply voltage to each module or unit in the circuit, thereby ensuring the stability of the circuit operation.
