What is a USB-C cable?
2025-01-01
The USB-C cable is a data transmission and charging cable that uses a USB-C interface, which is widely popular due to its versatility, high-speed transmission, and compactness. The USB-C interface can not only connect various types of devices, including computers, mobile phones, tablets, mobile storage devices, monitors, etc., but also supports high-speed data transmission and charging functions.
USB-C has the following main features:
1. Ultra-thin design
Old USB ports are 14mm * 6.5mm long, while USB-C is only 8.4mm * 2.6mm. This slim and compact design is suitable for a variety of devices, including smartphones, tablets, laptops, etc. Due to its small size, it will be more flexible and portable to use, especially in modern slim devices.
2. Reversible plugging and unplugging
The USB-C interface has no fixed plugging and unplugging direction, and either side can be plugged in, which is convenient for users.
3. High-speed transmission
The USB Type-C cable supports high-speed data transfer rates, which can achieve fast and efficient file transfer between devices. With the USB4 and USB 3.2 standards, the Type C cable can achieve data transfer speeds of up to 80 Gbps and 20 Gbps respectively, providing faster connection speeds compared to the old USB standards.
4. Strong power supply capability
The USB-C cable can not only transmit data, but also charge devices. It supports the USB Power Delivery (USB PD) protocol and can provide up to 240W of power, which is suitable for the charging needs of various devices, including laptops and other high-power devices.
5. Versatility
In addition to data transmission and charging, USB-C is also able to transmit audio and video signals. Many modern laptops and smartphones implement video output functions such as DisplayPort and HDMI through the USB-C interface, achieving multi-purpose use of one line.
6. Bidirectional transmission
Unlike the old USB port, where power can only be transmitted in one direction, the power transmission of the USB-C port is bidirectional, which means it has two ways to transmit power. This feature provides more flexibility in the data and power interaction between devices, such as mutual charging between two devices or bidirectional interactive transmission of data.
