USB-IF updates USB-C PD branding for 240W power delivery
The USB Implementers Forum (USB-IF) has updated the branding of USB-C cables and connectors with power delivery following the launch of the latest version of USB4.
The USB Type-C and USB Power Delivery (USB PD) specifications will be updated for power delivery up to 240W.
“USB Type-C is not USB Power Delivery,” says the USB-IF. “USB Power Delivery is a protocol/hardware solution that increases USB power capabilities up to 240W. These terms are not interchangeable. If a product features USB Type-C it does not necessarily support USB Power Delivery, USB 3.2, and/or USB4.”

The new Certified USB Type-C Cable branding will display cable power capabilities in watts, clearly indicating support for 60W or 240W as defined by the USB Power Delivery (USB PD) 3.1 specification.
All of this is key for the single USB-C charger required for equipment that can be shipped in the European Union.
“With the new higher power capabilities enabled by the USB PD 3.1 Specification, which unlocks up to 240W over a USB Type-C cable and connector, USB-IF saw an opportunity to further strengthen and simplify its Certified Logo Program for the end user,” said Jeff Ravencraft, USB-IF President and COO.
“With our updated logos, consumers can easily identify the USB4 performance and USB Power Delivery capabilities of Certified USB-C Cables, which support an ever-expanding ecosystem of consumer electronics from laptops and smartphones to displays and chargers.”
USB4.0 Version 2 also adds data rates up to 80Gbit/s, but this creates confusion with the Type-C connectors, which can support the USB3.1, 3.2 and 4.0 protocols.
“The USB Type-C cable and connector specification is a supplement to the USB 3.2 and USB4 specifications, however USB Type-C is not USB 3.2 or USB4. These terms are not interchangeable,” said the USB-IF.
The ratings are USB 40Gbps ; USB 20Gbps ; USB 10Gbps ; and USB 5Gbps
The USB4 logos will be updated in parallel to unify branding across the Certified USB logo programme ahead of the USB DevDays developer events planned for November. Protocol updates are also being made to enable higher performance USB 3.2, DisplayPort and PCI Express (PCIe) data tunneling to access the higher available bandwidth.
