This noodle style micro USB cable connects your USB Cable for HTC/Samsung/Blackberry etc, directly or through a dock to your computer's USB port for efficient syncing and charging or to the USB power adapter for convenient charging from a wall outlet.
got a couple of different colored ones, helps to find them, and keep them apart. got them for a week now and still working. wait and see, as any other micro usb cable seem to get broken after a while. fingers crossed these ones survive a few months.
