USB (abbreviation of Universal Serial Bus) is a connection interface between computer and peripherals or other devices. The Devices communicating via this interface can transmit power, data, touch signal and so forth.
USB, the revolution of connector, has replaced the traditional parallel port to become the widely used connector on computer, mouse, keyboard, printer, smartphone and other devices. The consumer electronics on our hands are almost equipped with USB. With three advantages- hot plugging, plug’n play, and speedy transfer rate, USB allows up to 127 external devices to be connected on one port without conflict.
The evolution of three USB versions can be subdivided according to the transfer rate as below:
In recent years, MacBook, laptops, Android phone, tablet PC, portable monitor, and even Nintendo Switch adopts USB Type-C.
💡 USB Type-C had a reversible and symmetrical 24-pin, with same 12-pin upper row and lower rows. A reversible USB-C plug simply allows the USB devices to be plugged into a port in either direction. Users won’t be concerned about the damage caused by inserting the plug incorrectly. Therefore, USB Type-C becomes a popular connector in force.
1. High Transfer Rate
The previous generations of connections, such as USB Type-A, Micro USB, usually support USB 2.0(maximum data transfer rate at 480Mbps). Nowadays, USB Type-C interface supports USB 3.2(data transfer rate at 5Gbps to 20Gbps). Moreover, the latest USB 4 supporting up to 40 Mbps data transfer rate can only be used on the USB Type-C interface.
2. Support USB-PD Fast-Charging Standard
USB-PD(USB Power Delivery) fast charging is a power delivery specification published by the USB-IF. USB PD fast charging adopts USB Type-C as its transmitting interface. Take phone charger as an example, common output power is around 2.5W to 5W. However, USB PD power rule defines four normative voltage levels at 5V, 9V, 15V and 20V and the power supply supports output power from 0.5W to 100W. Furthermore, USB PD 3.1 enable delivering up to 240W of power over full featured USB Type-C® cable and connector.
Various Android smartphones and Apple® products have adopted USB PD fast charging function. GeChic 21.5-inch 2101H portable monitor can supply fast charging power to the smartphone or laptop when 2101H connect to its 19V power adapter.
⭐ Not all USB Type-C interfaces support USB PD fast charging but if you hope to charge faster, only USB Type-C can make it!
3. Video& Audio Transfer
When the USB Type-C connector can transfer power, data and video and audio signals additionally. It is fairly an omnipotent port!
Besides familiar HDMI, VGA and DisplayPort, USB Type-C has also joined the video and audio transmitting territory. In recent years, many display protocols, including DisplayPort and HDMI standardized by VESA, and ThunderboltTM developed by Intel®, have adopted USB Type-C as their connecting interface.
USB Type-C compliant laptop, smartphone, and external monitor are gradually popularized. USB Type-C uses DisplayPort Alt Mode to enable video and audio transmission at 4K+ resolution and still supports USB and power signals.
For the laptop or game console which supports USB Type-C(DP Alt Mode), a low-power-consumption portable monitor can use merely one USB Type-C cable for power, video and audio signals. Bring the monitor with your game console to have fun on the go. Or, easily set up dual-screen or triple-screen laptop!
Check the table below to learn which model of GeChic monitor supports USB Type-C.
USB Implementers Forum (USB-IF) regulates the USB Logo marking rule. Only the products certified and authorized by USB-IF have the right to be licensed to use USB-IF logos; even so, it doesn’t mean the connectors and cables without the markings don’t support specific functions of USB-C.

How to identify the Common USB Type-C marking:
If your device is equipped with a USB Type-C port, you can choose cables for it according to its version and function. The device’s original cable is definitely the first choice. If you buy cables from third brand, you must check whether it supports the specification that you need such as USB 3.2, USB-PD or DisplayPort (Alt Mode). Generally, the charging efficiency, signal quality, and transmission stability will decrease as the longer the cable is. Hence, the recommended maximum length is as below: 5m(16ft) for USB 2.0, 3m(9ft) for USB 3.2, 0.8m(2.6ft) for USB4.
With the evolution of the USB version, the popularization of USB Type-C on consumer electronics is in sight. After reading this article, the next time you get a new monitor or smartphone, fully utilizing the USB Type-C will be easily for you!
