![]() ![]() The trick is that you have to have the right cable for the right voltage. (The spec has been updated to 3.0 with additional smarts about multiple connected devices, but it’s fundamentally the same.) USB-C allows up to 100W of power by incorporating the Power Delivery 2.0 specification from the USB trade group. AnkerĪnker’s USB-C cables are sleek and featureless. Before USB-C, even though it was possible to carry laptop levels of power over a USB cable designed for that purpose, manufacturers generally avoided this-probably to avoid cable confusion. The trouble intrudes when we talk about power delivery, a separate part of the USB specification and incorporated into USB-C and Thunderbolt 3. It can also carry all the kinds of traffic noted above for “plain” USB-C devices. It was built to work only with the USB-C connector style and specification. Thunderbolt 3 is a data-transfer standard that can carry up to 40Gbps of information. Hardware devices-like the 2015 to 2018 12-inch MacBook and some non-Apple smartphones, tablets, and laptops-use USB-C to carry USB 2.0, 3.0, and 3.1, as well as ethernet networking and DisplayPort/HDMI video signals (and even DVI and VGA!) via adapters. USB-C is a broadly defined connection and cabling format, rather than a protocol for defining specific kinds of data that passes over it. ![]()
