Given that the new Macbook has only one USB-C port, can you indefinitely run your laptop while connected to a TV?
Let's say a TV run on electricity from a wall power outlet. You connect your macbook to it and play a video from your macbook to be displayed on the TV.
Does USB-C keep your macbook charged while connected to a device that has its own power source? Or will I need to disconnect the macbook from the TV, charge for a while, and then connect it back to the TV once the macbook gets charged enough?
What about if the macbook is connected to a display that run on battery power? Will the macbook charge the display (e.g. tablet), the tablet charge the macbook, or be power-neutral?
