2021: Standard announcement for power monitors and laptops via USB cable
At the end of May 2021, the non-profit organization USB-IF introduced the USB Type-C 2.1 standard. It will allow you to connect energy-intensive devices such as gaming laptops, docks, 4K monitors and printers, supporting up to 240 watts of transmitted power against 100 watts of the previous generation standard.
The new USB Type-C 2.1 cables will be marked Extended Power Range or EPR. Such cables shall maintain current up to 5 amperes and voltage up to 50 volts.
 | We expect devices supporting higher power to appear in the second half of 2021, the USB-IF statement said. |  |
At one time, USB was positioned as a technology with useful but limited functionality. The interface was used to connect keyboards, mice, printers and similar peripheral devices to computers. Later, when the mobile revolution began, it turned out to be quite useful for charging phones, which paved the way for using USB to transfer not only data, but also energy. The extended power range option of 240W means that the USB usage range is likely to expand again.
New 240W cables will have to meet certain specifications. USB-IF reported that they will have special markings so that users are not accidentally misled and "can visually confirm that the cable supports up to... 240 W. "
240W is enough for large monitors, workstations, gaming laptops, and other devices. However, there are exceptions, and many gaming computers with powerful iron, as well as some laser printers, consume much more energy.[1]
