The USB Implementers Forum (USB-IF), the organization responsible for the USB standard, has announced revision 2.1 of the USB-C standard. The biggest change in it is the upgrade of the maximum charging power via Power Delivery from the previous 100 watts to 240 watts.
This is the USB-IF&s response to the problem that USB-C is intended to serve as a universal standard power connector not only for smaller devices but also for larger ones, such as notebooks, but that it is not sufficient for this when there is a greater hunger for power (>100W) and that it then has to be done via a proprietary power connector after all, which should actually be overcome.
The charging power of 240 watts per Extended Power Range, which will be possible in the future with the new standard, should be sufficient for the majority of devices, such as very power-hungry video editing notebooks with a powerful graphics card. However, this will require new cables, chargers and plugs that are adapted to the higher power - these will then provide information about their improved power delivery properties compared to the previous solutions via a special logo so that they are not confused.
