At present, there are three main types of mobile phone charger interfaces: Micro USB interface; USB Type C interface; The Lightning port.
In addition to the common USB-C interface on Android phones, Apple mobile phones currently use Lightning interface, which is a step ahead of USB-C to realize the double-sided plug-in design, and to this end, the MFi certification for iOS devices has been formed. On the latest iPad Pro, Apple has adopted USB-C interface for the first time.
USB Type C Main functions of the port
1. Fast
In theory, the maximum transfer rate of the USB-C port is 10Gb per second. But Apple says the new MacBook's USB-C port will have a maximum transfer rate of 5Gbps. The maximum output voltage is 20 volts, which speeds up charging. And USB-A, so far the limit transfer rate is 5Gbps, the output voltage is 5 volts.
2. Versatile
The USB-C port on the new MacBook can transfer data, charge and also serve as a video output port to connect to external display devices. The only question is how Apple will satisfy users who want to do all three at once.
3. Two-way
Unlike older USB ports, where power can only be transmitted in one direction, the USB-C port's power transmission is bidirectional, which means it can have two ways to send power. Therefore, the user can not only use the notebook to charge the mobile device, but also use other devices or mobile power to charge the notebook.
4. Backward compatibility
Usb-c can be compatible with older USB standards, but users will need to purchase an additional adapter to complete the compatibility. Apple said that not only will Apple officially sell the adapter, but third-party companies can also license production.
