1. Ultra thin
A thinner body requires thinner ports, which is one of the reasons why USB-C emerged. The USB-C port is 0.83 centimeters long and 0.26 centimeters wide. The old-fashioned USB port, measuring 1.4 centimeters in length and 0.65 centimeters in width, has become outdated. This also means that the end of the USB-C data cable will be one-third the size of the standard USB-A type data cable plug.
2. No positive or negative
Like Apple's Lightning interface, the front and back of the USB-C port are the same. That is to say, no matter how you insert this port, it is correct. Users don't have to worry about the pros and cons of traditional USB ports.
3. Fast
In theory, the maximum transmission rate of the USB-C port is 10Gb per second. However, Apple stated that the maximum transfer speed of the USB-C port on the new MacBook is 5Gbps. The maximum output voltage is 20 volts, which can accelerate the charging time. The USB-A model has a maximum transmission rate of 5Gbps and an output voltage of 5V so far.
4. A versatile hand
The USB-C port of the new MacBook can transmit data, charge, and also serve as a video output port to connect external display devices. The only question is how Apple can satisfy users who want to do these three things simultaneously.
5. Bidirectional
Unlike the old USB port, USB Type-C can only transmit power in one direction. The power transmission of USB-C port is bidirectional, which means it can have two ways to transmit power. So, users can not only charge their mobile devices with their laptops, but also use other devices or mobile power sources to charge their laptops.
6. Backward compatibility
USB-C can be compatible with old USB standards, but users need to purchase additional adapters to complete compatibility. Apple stated that not only will Apple officially sell adapters, but third-party companies can also authorize production.
