Until now, there was some confusion regarding which connector and cable could provide what power and data rate, but this from now on is going to end thanks to this new revision of the standard. Of course, you must bear in mind that this will only affect certified products and that, therefore, generic cables and connectors (OEM, “from the Chinese”, etc.) will not have any obligation to adopt these logos that, As you will understand, they will be very useful so that the consumer can choose the option that suits him best.
The new USB-C 2.1 logo already specifies its power
As specified by the USB-IF (USB Implementers Forum, which as you know are responsible for the development of everything related to the USB standard) has indicated that this new revision of the standard is designed to “alleviate consumer confusion”, and that affect cables based on specifications USB4, USB Type-C and USB Power Delivery.
Thanks to the new revision USB Type-C 2.1 and USB Power Delivery 3.1 for the standard with USB-C connector, they can now be transmitted up to 240 watts of power (48V and 5A) instead of the 100 watts that we had before this new standard (20V to 5A), and as you can see in the image that we have placed above these paragraphs, this is now much clearer through the new logos that They have published.
Thus, a USB4 cable certified to have a speed of 40 Gbps will have its corresponding logo, while a cable certified to transmit 240W of power will also have it. There are obviously also combined logos, and as you can see, the USB-IF has defined different logos for the packaging and for the cable itself, so that when we remove the cable from its packaging (and it goes to the trash), we can also identify the cable itself all its parameters without problem because it must carry the logo, simpler that yes.
Similarly, there is also a logo for USB chargers certified to provide up to 240W of power, chargers that will in all likelihood be sold as universal. Of course, when we talk about laptop chargers, the manufacturer will not have the obligation to incorporate the new logo that the USB-IF has designed for it (not so on the cable, as long as it is certified, of course).
This does not solve the problem at all
As we have mentioned before, the introduction of these logos is only obligatory for manufacturers adhering to the USB-IF certification program, a program to which no manufacturer is obliged to adhere. This means that there will be many manufacturers of accesories that do not include the logo and that they do not have to comply, therefore, with the specifications of the standard.
Therefore, when buying a USB-C cable for charging, it would be advisable to avoid manufacturers that do not include these logos both on the packaging and on the cable itself, no longer because of the confusion of the user who will not know what type of cable it is or what its capabilities are, but because they will not be able to be certain that it meets the promised specifications.
