Extra power for your USB 3.0 external HDD with 2x USB Type-A connections (one for power, one for data)!
Portable devices are really great, except that being portable, they often have demands too great for a single USB port to power them. If you're experiencing this problem, then this handy USB 3.0 Micro 10-Pin (male) to 2x Type-A (male) Y-Cable just might be what you're looking for.
This cable works like a regular USB 3.0 Data cable for your external HDD, with a Micro USB 10-Pin plug going to a standard USB 3.0 Type-A plug, only you get an extra USB Type-A plug to supply extra power from another port. How clever! This is especially handy for External Hard Drives and other high-power items which require additional power to run.
This cable is designed for a device which has a USB 3.0 Micro 10-Pin Female socket, so supply power and data transfers. If your device has the USB 2.0 Mini-B 5-Pin Female socket (as found on some older HDDs), you may need this USB 2.0 Mini-B 5-Pin to 2x Type-A Y-Cable instead.
