Charging multiple devices

Our experts will go over the different types of USB hubs and the definition of self-powered vs bus powered.


Types of USB port hubs


There are two basic types of USB port hubs: powered and non-powered. 
Powered USB port hubs receive power from the computer to which they are connected and can draw power to support devices with higher power requirements. 
Non-powered port USB hubs need an external power source, usually an AC adaptor, to provide the necessary power for devices requiring a high volume of energy. 

Both these types of USB port hubs are crucial for expanding the USB port connection possibilities of a single computer or other devices that utilize USB ports for various uses.

Self Powered vs. Bus Powered

When it comes to powered USB hubs, you have two primary options: self-powered or bus powered. A powered hub is powered externally through an AC plug, a separate port on the hub itself, or a combination of both. Bus-powered hubs draw their power from the laptop’s single USB-C port. 

If you're looking for convenience and fewer wires a Bus-powered solution like a USB-C Hub is ideal. But if you want maximum performance and flexibility, investing in a self-powered USB hub is probably best to give you more control over your device's power output.
