I am charging my iPhone from a newer Thunderbolt 3/USB C enabled MacBook (in my case MacBook Pro 2016) with USB C to lightning cable from Apple.
What I know is:
For example there is an iPhone 8/8 Plus/X or a newer iPad Pro 13
with computer (default(?)) or iPhone charger wall plug: 5W (5V 1A) with iPad charger or 2.4A powerbank USB A to lightning: 12W (5V 2.4A) with MacBook charger wall plug (29W or larger) USB C to lightning: 29W fast charging
Anything I do from a 2016 MacBook Pro 15 it seems I get the default charging speed (5W) through USB C despite the same USB C to lightning cable with the MacBook wall plug can fast charge (29W).
The USB C/Thunderbolt 3 standard though supports 100W. Is there a (highly likely unofficial) way to tell my Mac that the iPhone/iPad plugged in via the USB C to lightning cable would like to take a faster charge?
So is there a way to charge from a Mac an iPhone/iPad with 12W or 29W instead of the "default" 5W?
