Carrying these chargers and cables to charge different electronic devices all day is really annoying to me. My home is even more messed up with these things. The chargers for phones, laptops, cameras, and toys at home seem to be different. I also hate this. The charging hardware in my laptop bag weighs about 3 pounds, and I have to carry them around all day. However, the good news is that the type-c interface can replace the micro USB socket for operation. As a technical specification, the type-c and its brother USB power transmission (PD) will use one or two adapters to meet all your charging needs. This technology is worth looking forward to using only one cable.

The type-c interface is a type of charging interface that has gradually emerged in recent years. This interface type has faster transmission speed and stronger power transmission than micro USB. The biggest highlight is that the type-c interface does not need to distinguish between the front and back sides to insert into the phone, truly achieving blind insertion and direct insertion, while reducing the damage rate of the interface. The transmission speed is faster than previous interfaces, and the theoretical maximum transmission speed can reach 10Gbps, Low cost, easy to promote, and strong scalability. The power interface, USB interface, and signal interface can all be used as a type-c interface.

The operating principle of a USB socket generally consists of four wires, two of which are serial channels used to transmit data, and the other two are used to supply power to the device. The USB socket transmits data at a full speed of 12Mbps during operation, while for low-speed peripherals, the USB transmits data at a transmission rate of 1.5Mbps. At this point, the USB socket bus will automatically and dynamically convert between the two transmission modes based on the external device situation. USB is the bus based on token, similar to the bus of Token Ring network or FDDI token. Respond by accepting or sending data to the host. USB supports suspension rehabilitation operation to handle USB bus socket power supply. The internal system of the USB socket adopts a hierarchical star topology, which consists of three fundamental components: the host, hub, and functional devices connected to the bus through ports. At this time, the USB socket can operate together for device charging or data transmission.

USB socket 4-wire identification

Red wire: positive pole of the power supply (marked as+5V or VCC on the wiring).

Black wire: grounded (marked as GROUND or GND).

White line: Negative voltage data line (marked as Data - or USB Port -).

Green line: Positive voltage data line (marked as Data+or USB Port+).
