cyberpower battery powered hub is shit
why ?
well : you can power it with an ac/dc adaptor
or by plugin it to a pc
but it s not powered by the batteries !!!
what ? well, the batteries are used only if the hub is connected to the pc and the batteries switch is turned on !!!
that s so lame
and they write on the doc : mobile battery powered hub
what s its real use ? to save the battery of your laptop ??? lol/sad
