In just a few years, the USB-C port has spread everywhere since childhood. With a couple of exceptions, it’s the main charging, data and display port for almost all modern phones, tablets and laptops. Even the European Union has proposed to make it mandatory in all devices.
The problem is that the USB-C connector has always been relevant but different from other features of the USB protocol. USB-C cables can use 2.0 or 3.2 speeds, they can support multiple charging wattage, whether they have Thunderbolt support or not, and even Thunderbolt cables are either “active” or “non” May be active. The connector is the same, but the capabilities are not.
The group behind USB-IF has always chosen to address this issue, not with a top-down mandate, but with a certification and optional logo. Today, the group announced a new consignment of the logo (PDF) aimed at overcoming the USB-C 2.1 and USB Power Delivery (USB-PD) 3.1 standards announced earlier this year. Among other tweaks, the new logo includes USB 4 support as well as a maximum USB-PD charging wattage, ranging from the old maximum of 100 W to the new maximum of 240 W.
The new logo calculates both speed and charging rate, and can be used on different versions of device packaging as well as on cables and ports. As usual, since these logos are not required to be used, you can expect them to be a hit and miss. But buying USB-IF-certified and labeled accessories from reputable sellers is probably still the easiest way to avoid counterfeiting and end up with cables and chargers that they say they do.
