There are two power ratings available for USB devices – 60W or 240W – and devices will be able to specify which level of power they support. Additionally, the USB-IF also revamped its USB4 certification logos, which denote the maximum transfer speeds supported (40Gbps or 20Gbps). There are also specific unified logos for cables and devices that indicate both he data rates and charging speeds. Additionally, there’s a specific logo for certified USB chargers, denoting that they can deliver up to 240W of power to a device.

To clarify, this isn’t a new standard being defined today, it’s j…
