There are two power mode options for the USB 2.0 4-Port TetraHub™.   

 

The first is bus-power mode, which does NOT require the use of an AC 

power adapter. In this mode, the hub is provided with 500 milliamps for 

all 4 ports. This should be adequate for mice, keyboards, and other low 

power devices.   
 
The second is self-power mode, which requires the use of an AC power 

adapter. In this mode, each port is provided with 500 milliamps, allowing 

for additional hubs, cameras and other high-powered devices.
