Regarding USB Type-C charging - I have 2015 Chromebook Pixel LS with two USB Type-C ports (one on each side of the laptop). The charging works on both ports which makes sense and I'm fairly sure this is the first ever laptop to allow charger to be plugged in on both sides of the laptop - convenience not to be underestimated. So from my point of view USB Type-C charging should work on every USB Type-C port.
