Use this adapter to adapt your USB power supply with large 5 Volt power adapter to almost any other USB Hub, card reader, and other devices that use the small 5V power adapter!
Simply connect your power supply unit to the USB device you need at the moment.  Please note that the power requirement of the USB devices must need exceed the output current of your power adapter - you can find the latter figure on the label of your power adapter.
