The USB Implementers Forum has unveiled the logos manufacturers can put on USB products that support 240W charging. It concerns five logos for chargers and cables, among other things.
According to the USB-INF organization responsible for the USB standard, the new logos are designed to provide consumers with a “simple way” to provide the performance and energy characteristics of certified USB cables, hosts, devices and chargers. That should happen with the addition of five logos for 240W charging, divided into three categories.
For example, there are separate logos for the packaging and the products themselves with regard to cables and chargers, but there is a separate category for the combination with USB 4 40Gbit/s, or USB4 Gen 3×2. Consumers should therefore take into account that there are also USB 4 20Gbit/s products with logo for 240W charging and USB 4 40Gbit/s variants with charging at 60W. More information about the different USB variants and Power Delivery can be found in the background article The USB standard remains unclear.
Support for 240W charging was added with revision 2.1 of the USB-C specification, released earlier this year. That revision brought the arrival of the Extended Power Range for charging via USB Power Delivery, which allowed configurations with voltages from 28V to 48V, at a current of 5A.
