Type-C main functions
In theory, the maximum transmission rate of the USB-C port is 10Gb per second. But Apple says the highest transmission rate for the new MacBook's USB-C port is 5Gbps. The maximum output voltage is 20 volts, which can speed up the charging time. The USB-A type, so far the limit transmission rate is 5Gbps, and the output voltage is 5 volts.
2. multi faceted hands
The USB-C port of the new MacBook can transmit data, recharge and link external display devices as a video output port. The only question is how Apple meets the users who want to do the three things at the same time.
USB Type-C is not like the old USB port, and the power can only be transmitted one way. The power transmission of the USB-C port is bidirectional, which means that it can have two transmission power modes. Therefore, users can not only use the notebook to charge the mobile devices, but also use other devices or mobile power to charge the notebook.
4. backward compatibility
USB-C can be compatible with old USB standards, but users need to buy extra adapters to complete compatibility. The Apple Corp said that not only apple officials would sell adapters, but third party companies could also authorize production.
