USB Type-C's connector and receptacle are smaller sized (comparable to Micro-USB) and more durable, withstanding 10,000 insertions/removal cycles. With symmetrical 24 pins, the connector will attach to the receptacle on the first try.
Up to 100W of power delivery
USB 2.0, 3.1 Gen 1, and 3.1 Gen 2 capable
Support for alternate modes, to allow for more than just USB data to be sent across the connector and cable assembly
Standard driven from computer and Mobile phone manufactures who needed a smaller better interface for USB.
Cables are electronically marked to allow for power delivery negotiation
USB-C ports may be providers or consumers of power
Cables and connectors will also have varying capabilities
e.g. - a port or cable may only support USB 2.0, and no power delivery
Identification of capabilities becomes important!
