Powered USB Hub

An external power supply is used by powered, or active, USB hubs to bring each hub port's energy level to par with an on-system port. Most frequently, a wall outlet is used to power active USB hubs. Active USB hubs nevertheless divide data bandwidth among all connected devices even though they are not required to divide power consumption among all connected devices.

Un-Powered USB Hub

Non-powered, also known as passive, un-powered USB hubs rely solely on the USB port on the computer for power. Unpowered hubs can't operate properly with devices that demand more power than the hub can supply.
