Sick of all those big power transformers hogging a socket on your powerboard just to charge a phone dock or run a tiny video converter? Well, now you have the option to power those devices via USB! Any small electronic device which can accept a 5.5mm Barrel Plug and runs of 5V / 500mA power is suitable for connection to a USB socket using this cable.
