Not sure about the connector, but I have heard reports that some cheaper USB cables with thinner-gauge wires already cannot handle the current from some chargers that are on the market. I can imagine USB-C only makes this more of a concern, since the USB Power Delivery spec allows up to 5 A @ 20 V.
