USB-C with 60 and 240 watts: New logos are supposed to explain chaos in the standard

The USB Implementers Forum (USB-IF), which is responsible for the USB standards, has published new logos for USB-C cables and connectors, which are intended to make the chaos of which connector and which cable can provide which power supply and data rate a little easier to understand. A distinction is made between 60 and 240 watts.

With the new revision USB Type-C 2.1 and USB Power Delivery 3.1 for the universal connection standard with USB Type-C connector, the power supply has been expanded. With USB Power Delivery, USB-C 2.1 now enables up to 240 watts (48 volts at 5 amps) instead of a maximum of 100 watts (20 volts at 5 amps) via the plug and the cable. Once again, USB-C did not make it easier to understand when which transfer rate and which maximum power supply can be used.

Many new logos are intended to provide clarity

The new logos should now make it clear at a glance whether 60 or 240 watts are provided according to USB Power Delivery 3.1. If it is a certified USB-4 connection, the data rate of 40 Gbit / s can also be included in the logo, after all, USB 4 can only be offered with 20 Gbit / s. Corresponding logos are also to be introduced for a power supply of a maximum of 60 watts and a transfer rate of a maximum of 20 Gbit / s. There is also another logo for chargers that shows the power supply. A total of seven different logos result for 240 and 60 watts alone, depending on whether they are printed on the packaging or the connection and with or without a data rate.

It remains to be seen whether the new logos will bring more clarity and compatibility. Since the USB-C connection now supports a wide variety of data rates and power supplies depending on the version of the standard, which cannot be seen on the cable, for example, it can hardly be more opaque for the user.
