Today, USB-IF announced the official launch of the USB PD 3.1 version. In the new version, the USB-C port will be able to transmit a maximum of 240W power. Before this standard, the maximum power of the USB PD standard was 100W (20V/5A). The newly added 240W is achieved by adding a 48V voltage range, which can correspond to the power supply of high-power notebook computers.

USB TYPE C


The important updates of the USB PD 3.1 specification are as follows: on the basis of the previous 5V, 9V, 15V, and 20V, three fixed voltage gears of 28V, 36V, and 48V have been added; 100mV is a step change to meet the equipment needs.

Official Announcement

Because of the increase in power, the technical specifications that 100W~240W PD hardware needs to pass are more stringent. At the USB Developers Conference 2021 to be held in the second half of this year, USB-IF will announce more technical details of the new USB PD and USB-C specifications.
