A:Answer YES ... The USB-C Thunderbolt port transfers both data and power (i.e. charges the laptop).
Side Note: This is a nice feature for compatible port replicators to provide desktop connectivity (external monitors, keyboard, etc) with a single cable that also charges!
If you are interested, I was able to find a port replicator that uses the USB-C Thunderbolt technology, allowing a single cable to provide BOTH data transmission AND power (charging the laptop) ... very nice!

Others that may work, but I have NOT tested are:
