USB-IF tries to clear confusion around USB Type C with new guidelines
USB Type C can be confusing for many people. USB Type C comes with varied specifications and lately, it has become tough for consumers to identify what the particular specifications of a USB Type C is.
Even though, all the USB Type C looks the same (and has the same connector) it can vary in terms of data transfer speed and power delivery standards.
USB Implementation Forum has come up with new branding to clear up this confusion. These changes are done in sync with the recent USB Power Delivery 3.1 specifications which were released earlier.
This has lead to USB-IF releasing a bunch of new Certified USB Type C Cable logos to display its power delivery capability which can be 60W or 240W. They have also updated the USB 4 logos to unify the Type C branding all across.
USB Type C can have a transfer speed standard of 20 Gbps or 40 Gbps and with two different power delivery standards of 60W or 240W.
This might still be confusing to many people but as consumers, you can have a little bit more understanding of what specification your USB Type C comes with.
It is worth noticing that these specifications (combinations of power and data speed) are not tied together. You can have a charger with a power delivery of 240W and a cable that has just 20 Gbps of transfer speed.
Or you can have one where you have low power delivery but higher transfer speed. As a consumer, you must be aware of this and get the specifications that match your need. Let’s say you are getting one for just transferring files, there is no need of getting one with 240W power delivery.
USB Type C has gone through many evolutions which definitely made it difficult to conform to standardised specifications like the newer Thunderbolt 4. USB-IF says that “certified USB solutions ensure interoperability and backwards compatibility in the marketplace.”
It needs to be seen whether this will help clear confusion surrounding the USB Type C ecosystem which seems like a mess right now.
