CALANDIS Standard B Male To Dual USB 2.0 A Type Y Cable With Extra Power Connector for Printer & Scanner External Hard Disk Drive (80cm) (USB Printer)

Please Note: This cable is not designed to split USB signals to multiple computers. The two USB A connectors are meant to plug into USB ports on the same computer. When a standard USB cable cannot transfer enough power to operate an external device, you need a USB 2. y-cable. Simply plug this cable's Standard B Male end into the device, and then plug the two USB A ends into open USB ports on one desktop PC or Mac. This cable then pulls power from both USB ports, and thus increases the output to the external drive. The red snagless hood on the auxiliary USB A connector enables the user to quickly distinguish between main and auxiliary power. Connectors: 1 Standard B Male to 2 USB type A Male USB 2.0 compliant.
