Good to know thx.USB-C PD charges the iPad 7 at 15W instead of the normal 12W. As you can guess though, that has pretty negligible effect on charging time.
Also, old news, but I wasn’t aware of this: The iPad Pro 10.5 can charge at the full 29 Watts with the MacBook USB-C charger. No wonder it is so much faster for charging. I had missed this thread:
29W Fast charging tests and 3rd party adapters
(10/8/2017) tldr; Chart of % gain over minutes for the Anker 30W charger described below, in case you just want to verify that your charger is charging at full speed. --- Original post follows: I finally managed to get my hands on both the 2nd gen iPad Pro 12.9" and the new iPad Pro 10.5"...
