The USB specifications allow for running more than one device off a single USB plug. USB C is no different and has a splitter available to make this happen.
It is possible for a USB socket to to connect to more than a single device at any one time. No need to unplug one device to then attach another. You need a USB splitter type of device to share the USB port.
USB C is the latest version of the USB specifications that started with the first iteration of USB back in 1996. USB-C has its very own hardware interface (the USB-C plug and socket) that shows up the incompatible differences it has with earlier USB plugs and sockets.
USB 3.2 is the data doubled version of the previous USB3.1 specification. This new specification also brought with it, the USB-C socket and plug, that has become so important to us today.
USB-C and USB 3.2
USB-C goes perfectly with USB3.2 to give a compact universal USB plug/socket with high speed data transfer that could only have been dreamed about in 1996.
Expanding the USB-C
The USB-C splitter is called a HUB. Its a device that has a USB-C plug on a lead that runs to a row of USB-C sockets. All of these sockets are connected to the USB-C plug. This effectively makes it a USB-C splitter but the correct terminology is a USB HUB.
USB Hubs are the way to expand the number of available USB sockets on a device. In the early days of the USB specification there would be only one or possibly two USB sockets available. This kept the manufacturing costs lower yet enabled more USB ports be added with the use of a Hub. USB-C is no exception to the hub problem and there are very good quality USB-C hubs available here.
Headphones and Power
What if you need to charge the phone and listen to the USB-C headphones at the same time? Do you need to buy a hub?
No, if you are only interested in using the power capabilities of USB-C and that is usually to charge a phone then a basic USB-C ‘Y splitter’ will be just what you need. These Y-Splitters are less bulky than a hub and if you don’t need the hubs capabilities of data transfer to multiple devices a Y spliier could work for you. Particularly owners of the latest Samsung and Google Pixel phones can use one of these USB-C splitters.
Splitters Vs Hubs
A USB C splitter will only do two things. Usually power a phone while allowing an external device to connect, quite possibly some headphones.
A USB-C Hub will allow the data connection to multiple devices, from 4 to many more, each device attached to the hub is treated as if it was connected to the host.
