USB Type-C data cable main function

1. Fast

In theory, the maximum transfer rate of USB-C ports is 10 Gb/s. But Apple said that the new MacBook's USB-C port has a maximum transfer rate of 5 Gbps. The maximum output voltage is 20 volts, which can speed up the charging time. The USB-A type, up to now, has a limit transfer rate of 5 Gbps and an output voltage of 5 volts.

2. All-rounder

The new MacBook's USB-C port can transfer data, charge it, or link it to a video output port as an external display device. The only question is how Apple meets users who want to do these three things at the same time.

3. Two-way

Unlike older USB ports, power can only be transmitted in one direction, and USB-C port power transmission is bi-directional, which means it can have two types of transmit power. Therefore, the user can not only use the laptop to charge the mobile device, but also can use other devices or mobile power to charge the notebook.

4. Backward compatibility

USB-C can be compatible with the old USB standard, but users need to purchase additional adapters to complete compatibility. Apple stated that not only did Apple officially sell adapters, but also third-party companies could authorize production.
