In addition to higher transfer speeds, improved bandwidth allocation, and backward compatibility, USB4 will also offer Power Delivery at up to 100 Watts since it utilizes the USB-C port. Many USB-C ports prior to USB4 already support this but Power Delivery may be universally available with USB4, though not necessarily at 100W. While some newer devices (primarily laptops) with a USB Type-C port can be charged via that connection, not all of them can, which can lead to consumer confusion. When implemented by the host, USB4 will also use intelligent Power Delivery. This will allow a USB4 cable to deliver as much power as a connected device requests, up to 100 Watts. Even better, the Power Delivery over USB4 is bi-directional, allowing power to flow to and from a connected device.
