Hi, Couldn't find this information, but just want to know if the newest macbook pro's type c port charge an iphone as fast as the older usb-a macbook pros. What is the power output of the usb-c ports? 5 watts, or 12 watts, 18 watts? I think USB is always 5 volts, but the current could be .5A 1A, 2.1A, or even more. What I really care about is if there is a regression in charging speed when using the latest macbook pros. I actually have come to use my laptop (old mbp 2015) to charge my phone alot and it's quite fast (2.1A I believe).
