I'm still annoyed they didn't ship it with a Type-A -> Type-C cable. Would that have ruined their ability to do the fast charge? Because if not, it would be really nice to not have to bottleneck it through an adapter or buy new PC hardware that supports a Type-C port to xfer data or charge it via PC.
Yes. Type A->Type C cables, according to standard, are only allowed to charge at Type A speeds. The only way around this is to buy a non-compliant cable with the Type C-C resistor in it (and be very careful what you plug it into to avoid causing a fire/explosion/worse).
