Type-C connection explained:
USB-C is a new connector shape generally released from 2015, the connector itself supports USB 3.1 and USD PD (Power Delivery) which allows power to be delivered to your device to charge, eventually the large USB type should disappear, as USB only delivers power one way and USB-C has the massive benefit of both ways. So the USB type C will become the industry standard and all many other form of USB micro, USB mini and USB used on phones, tablets and many other gadgets due to the size will now be able to house this small connection. So no more having five or more different size USB cables for your entire home and office devices, one cable will fit them all.
USB-C ports can support many different tasks with adapters that allow you to connect to displays via HDMI, VGA, display ports, DVI, so again one cable will do it all.
This USB type C does not fit certain models of iPad Pro, so if your Ipad Pro has the lightning connector, then you will need the fast charge 30w plug and USB to lightning adapter listed below.
