Cheap Chinese plastic junk. It was cracked and falling apart. Type-A USB ports connect as a pass-through, but draw too much power from the port. A typical USB 2.0 Type-A port provided 5 volts at MAX. 500mA. This is useless Chinese bullshit. I wish I could return it but Revane dropped the package at my apartment door three days before I arrived and it got wet because it rained here in Houston. So I ran out of money. Do yourself a favor? Don't buy this junk.
