USB Type-C (abbreviated as Type-C) is a hardware interface specification for the Universal Serial Bus (USB). The highlights of the new version of the interface are a slimmer design, faster transfer speeds (up to 10Gbps) and more powerful Power delivery (up to 100W).Type-CThe biggest feature of the double-sided pluggable interface is that it supports double-sided insertion of the USB interface, thus officially solving the problem of "USB cannot be inserted correctly" worldwide, and the front and back can be inserted at will. The USB data cable must be thinner and lighter.

USB Type-C has the following characteristics:

1. The maximum data transfer speed reaches 10Gbit\/sec, which is also the standard of USB3.1; the Type-C interface can be a two-way power supply, which can charge the device itself or power external devices.

As long as your phone supports OTG function, it can power other devices, such as wireless earphones, external speakers, etc., to relieve emergency needs.

2. The size of the Type-C interface socket end is about 8.3mm2.5mm thin design;

3. It supports the "positive and negative insertion" function, which can be inserted from 2 sides and can withstand 10,000 repeated insertions and extractions;

4. The standard specification cable equipped with Type-C connector can pass 3A current, and also supports "USB PD" which exceeds the existing USB power capacity, and can provide a maximum power of 100W.

In theory, the USB Type-C port has a maximum transfer rate of 10Gb per second. But Apple says the new MacBook's USB Type-C port has a maximum transfer rate of 5Gbps. The maximum output voltage is 20 volts, which can speed up charging. For USB -A type, the limit transfer rate so far is 5Gbps, and the output voltage is 5V.

The new MacBook's USB Type-C port can transfer data, charge, and can also be used as a video-out port to connect to an external display device. The only question is, how does Apple cater to users who want to do all 3 at the same time. The Type-C interface has various speed standards, and the Type-C docking station equipped with the high-speed interface is very expandable. Not only can it charge, data transfer and other functions, but the Type-C interface can also be used as a multi- an interface.

Most Type-C interface phones only need to be plugged into the docking station to connect the mouse, keyboard, hard disk and other devices.

Unlike older USB ports, power can only be delivered in one direction. The power delivery of a USB Type-C port is bidirectional, which means it can have 2 modes of delivering power. So users can not only use laptops for mobile devices You can also use other devices or power banks to charge your laptop.

USB Type-C can be compatible with the old USB standard, but users need to buy 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 the production. H
