In only a few years, the USB-C port has gone from infancy to ubiquity. Except for a couple of exceptions, it’s the most important charging, information, and show port for almost all fashionable telephones, tablets, and laptops. The European Union has even proposed making it mandatory in all devices.
The issue is that the USB-C connector has at all times been associated to however separate from the opposite specs within the USB protocol. USB-C cables can use 2.0 or 3.2 speeds, they will assist a number of charging wattages, they will both have or not have Thunderbolt assist, and even Thunderbolt cables could be both “lively” or “passive.” The connector is similar, however the capabilities aren’t.
The group behind USB-IF has at all times taken a hands-off method to this downside, selecting to resolve it not with top-down mandates however with certification and optional logos. Immediately, the group announced a brand new batch of logos (PDF) meant to demystify the USB-C 2.1 and USB Energy Supply (USB-PD) 3.1 requirements that have been announced earlier this year. Amongst different tweaks, the brand new logos account for USB 4 assist, in addition to an elevated most USB-PD charging wattage, from the previous most of 100 W as much as a brand new most of 240 W.
The brand new logos account for each velocity and charging fee, and totally different variations can be utilized on the gadgets’ packaging in addition to the cables and ports themselves. Per typical, since utilizing these logos is not necessary, you may anticipate adoption of them to be hit-and-miss. However shopping for USB-IF-certified and labeled equipment from respected sellers remains to be in all probability the best approach to keep away from counterfeits and to finish up with cables and chargers that do what they are saying they do.
