I have a 2018 iPad Pro and a recent MacBook Pro (with USB C). Is there any way I can control what charges what when I connect the two? If I connect the two with a USB-C charger, my MacBook automatically starts charging my iPad. Can I have it work the other way around? Can I have it not transfer power, and just be used to transfer data (like for Sidecar)?
This poses a more general question about USB-C: How can you control what direction power goes? I have a USB-C Battery that automatically charges my laptop or iPad when I plug it in, but as soon as the battery dies, the MacBook/iPad will start charging the battery!
