The speed of a USB port or cable will soon be much easier to determine. The USB-IF organization responsible for standardizing USB decided to remove the USB SuperSpeed or USB4 marketing designations by replacing them with specific indications of the power and speed of transmission.
Three types of symbols are proposed for ports on the devices: one used on the package, the others on the body of the gadget itself. This will be the red-blue logo of Certified USB as well as the data speed symbol: 5, 10, 20 or 40 Gbit/s. The figure of 80 Gbit/s adopted in the USB42.0 standard may appear some time later. If the device supports not only data transmission but also charging through the USB port, the symbols shall be placed on the surface of the battery icon.
For chargers, there are two versions designed for simple and fast charging: Certified USB charger and Certified USB Fast Charger, respectively, with a support power in watts. It is, however, somewhat surprising that the "rapid charge" sample is limited to only 100 W and simply "charged" to 240 W. There is a theory that the term "rapid charge" refers to the USB-PD 3.0 PPS standard, which provides for the ability to adjust the voltage to the battery charge level.
Finally, there are two versions of the USB-C cable symbol: for the package and for the cable itself. The red-blue logo for the package is accompanied by the charging power and data transmission speed. On the cable itself, the logo version is simplified. The exception is the Hi-Speed USB cable, which combines the outdated USB 2.0 protocol at a speed of 480 Mbit/s and the USB-PD 3.1 standard with a capacity of, for example, 60 or 240 W, only the power is specified.
