USB-C is the same as as any other USB standard the only difference is the design. USB-C is the replacement to types A and B. Now you no longer have to do the USB flip because its universal. Its supports up to 15 wats of power to external devices like thumb-drives and iOS devices (using lightning to USB-C cable available at Apple). They, like USBs A and B, are backwards compatible with USB versions 2.0, 3.0, and 3.1. USB-C is nowhere as fast or power full as Thunderbolt 3. Although some of the advantages include consuming less power which is helpful for portable devices like the MacBook.
