There are 3 kind of USB hubs.
Non-powered, or passive, USB hubs do not have an external power source and only pull power from the computer's USB port, limiting the maximum power to single USB (splitting).
Powered, or active, USB hubs use an external power source to bring each hub port to the same energy level as an on-system port, but not to charge them.
mostly have one (or more) of the USB ports capable of charging devices
