USB Type-C v2.1 standard specification released: Increased power supply up to 240W

There used to be various interfaces on the motherboard, including ISA, PCI, AGP, AMR, CNR, FDD, IDE, and SATA, etc. However, in the past ten years, the PCIe standard specifications have gradually unified the interfaces on the motherboard. Now assembling a host, the plug-in has been greatly simplified, and most of the connected devices are PCIe channel devices

USB Type-C

The USB-IF Association has just released the USB Type-C v2.1 standard specification. The biggest change is to increase the power supply of the highest 20V/5A under the PD protocol to 48V/5A. To put it simply, it has been increased from 100W to 240W, which is quite large. In the future, most electronic devices including gaming notebooks can be powered by USB cables. For mobile phones, there are not too many differences. The current standards are sufficient, but devices that require higher power such as gaming laptops and microcomputers may be different in the future.

However, USB Type-C v2.1 standard specification requires a new extended power range (EPR) cable instead of the current standard (SPR) cable. This may mean that SPR cables will be replaced by EPR cables. It is conceivable that USB 4 and USB Type-C v2.1 will eventually become a unified interface for various electronic digital products. For ordinary consumers, it is very convenient to use only one USB cable to meet the charging and data transmission needs of all electronic devices in their hands in the future.
