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.

Charging time varies according to settings and environmental factors actual results will vary.USB-C is a broadly defined connection and cabling format, rather than a protocol for defining specific kinds of data that passes over it. Fast-charge testing conducted with drained MacBook Pro units. 16-inch MacBook Pro systems tested with pre-production Apple 140W USB-C Power Adapter (Model A2452), and 14-inch MacBook Pro systems tested with pre-production Apple 96W USB-C Power Adapter (Model A2166), both with pre-production USB-C to MagSafe 3 Cable (Model A2363).

Testing for MacBook Pro conducted by Apple in September 2021 using pre-production 16-inch MacBook Pro systems with Apple M1 Max, 10-core CPU, 32-core GPU, 64 GB of RAM and 8 TB SSD, and pre-production 16-inch MacBook Pro systems with Apple M1 Pro, 10-core CPU, 16-core GPU, 16 GB of RAM and 1 TB SSD, as well as pre-production 14-inch MacBook Pro systems with Apple M1 Max, 10-core CPU, 32-core GPU, 64 GB of RAM and 8 TB SSD, and pre-production 14-inch MacBook Pro systems with Apple M1 Pro, 8-core CPU, 14-core GPU, 16 GB of RAM and 512 GB SSD. Charging time varies according to settings and environmental factors actual results will vary. Fast-charge testing conducted with drained MacBook Air units. MacBook Air systems tested with Apple 67W USB-C Power Adapter (Model A2518) and USB-C to MagSafe 3 Cable (Model A2363). Testing for MacBook Air conducted by Apple in May 2022 using pre-production MacBook Air systems with Apple M2, 8-core CPU, 8-core GPU, 8 GB of RAM and 256 GB SSD. Find out how to identify your Mac power adapter. If you're not sure which Apple power adapter you have, check the wattage on the top or bottom of the adapter.
