C2G 81578 2M USB B Male to 2 x A Y Cable, 2.0 ideal for powering Hard Drives, Black

C2G 2m USB-B male to 2 x USB-A male Y cable, USB 2.0 Ideal for powering hard drives When a standard USB cable cannot transfer enough power to operate an external device, such as a portable 2.5in hard drive, you need a USB 2. Y-cable. Simply plug This cable's USB B 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. Foil and braid shielding reduces EMI/RFI interference, and twisted pair construction reduces crosstalk for high speed, error-free data transfer. This cable is compatible with USB 1., 1.1, and 2. Specifications 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 Please note: both the red and black USB-A leads measure 2 metres in length for extra flexibility and point of difference to all other brands
