The USB-C interface is now popular on most new laptops, but some laptops still use the USB-A interface for some considerations. According to news from the industry chain, notebook manufacturers will make the USB-C interface the standard configuration of notebook computers in 2022, which is the C port commonly used in our Android phones.
The benefits of USB-C unification
Although the C port has high versatility, different C port standards are also different, and the power supply and data transmission speed are different. 65W and 90W power supplies are more common, and those above 100W are relatively high-end. The latest standard has reached 240W, but the popularity is not enough.At this stage, computer data transmission is still 10Gbps. If it is Thunderbolt 4/USB4, it can reach 40Gbps, but the cost is relatively high. According to the current situation, there is a high probability that 20Gbps will be popularized next year.
For our consumers, it is a good thing to popularize the USB-C interface. The data transfer rate can be increased, and the charging interface can be unified, so that you don’t need to bring a large-head DC charger when traveling on business.
Not only that, but you can also connect the monitor through the USB-C interface for video signal transmission. Coupled with a green-linked docking station, you can also do multi-port expansion operations with one port. U disk, mouse, keyboard, and screen projection are all satisfied.
Reasons for slow development
In this way, the role of the USB-C interface is really big. Then why is the development of the USB-C interface so slow in the past ten years? There are many reasons for this.
The first point is the opposition of Apple and the USB-IF organization to mandatory unification. The reason why Apple opposes is simple. The reason is that it is not environmentally friendly! Everyone knows that Apple’s move is to maintain its own business. After all, certification of lightning interfaces and accessories is an industry chain worth tens of billions.
The objection of the USB-IF organization was unexpected to many people, and the official organization actually came to oppose it. Their argument is that the USB-C interface is outdated, and the latest developments are not considered; the mandatory use of the USB-C interface will decouple from the ecology of other types of interfaces, and consumers should be allowed to choose which popular interface.
There is also the charging protocol part. The European Union’s USB-C standard supports Qualcomm’s QC charging protocol, but the USB-IF organization will not certify this type of standard. What they mainly promote is the PD charging standard. After all, it is a problem of benefit distribution.
