USB OTG cable has lot of usages. And it can used on Android smartphone like Samsung Galaxy S III and Android tablet like Google Nexus 7. Besides connect it to Logitech Wireless Gamepad F710 to play games, I use it to connect to Samsung Galaxy S3 and Nexus 7 with Logitech Stereo Speakers Z110 for music and video. Logitech Stereo Speakers Z110 is a USB powered speakers. A perfect combination with Samsung Galaxy S3 and Nexus 7 due to its compact size and can draw power from the devices themselves.
