5V
or 12V PoweredUSB connectors can ONLY be used for
products with 5V or 12V power input respectively.
2
Some
products such as 3.5"external HDD may require
both 5V and 12V power input simultaneously and therefore
the PoweredUSB function does not apply to such products.

Please check the voltage requirement of your products
before charging it with PoweredUSB.
