Functions of typec connector
1. Two way transmission
Unlike the old USB port, the power can only be transmitted in one direction. The power transmission of the USB-C port is bidirectional, which means that it can have two power transmission modes. Therefore, users can not only use laptops to charge mobile devices, but also use other devices or mobile power to charge laptops.
2. Strong compatibility
Typec connector has the advantages of flexibility and versatility, which can be called "all-purpose interface". This connector supports multiple protocols. With the help of an adapter, it can also be backward compatible with HDMI, VGA, DisplayPort, and more interface types through a single USB C-port. The same USB Type-C interface can handle power, data, audio and video.
3. Generalist
The USB-C port of the new MacBook can transmit data, charge, and also be used as a video output port to link external display devices. The only question is how Apple can satisfy users who want to do these three things at the same time.
4. Efficient and fast transmission rate
Theoretically, the maximum transmission rate of USB-C port is 10Gb per second. However, Apple said that the USB-C port of the new MacBook has a maximum transmission rate of 5Gbps. The maximum output voltage is 20V, which can accelerate the charging time. The USB-A model, so far, has a limit transmission rate of 5Gbps and an output voltage of 5V.
