F56 30cm USB 2.0 A male to USB 2.0 A male + USB 2.0 B male data/power cable adapter With this USB 2.0 Y cable you can supply devices such as external housings with power and transfer data via two free USB ports. If a standard USB cable can't carry enough power to power an external device, such as a 2.5-inch portable hard drive, you'll need a USB 2. Connect the Y-cable end of the cable to the device, and then plug the two USB-A ends into open USB ports on a desktop PC or Mac. This cable then draws power from both USB ports, increasing performance for the external drive. If you purchase more than 10 pieces you will receive an additional discount.
