Hello, I read this article https://www.macstories.net/ios/testing-apples-29w-usb-c-power-adapter-and-ipad-pro-fast-charging/ stating that we could use the new usb-c power adaptor for macbook ( the 29W one ) to charge our ipad pro 12.9 faster. I asked about it to the Apple care and they didn't know anything about it apart that it's not the original power adaptor for ipad pro 12.9; what is it then, just a nerd thing that maybe works but could damage the ipad or shorten its battery life or is it for real?
