[SOLVED] A small USB pcnowered fan

A small USB powered fan

I don't know allot about electronics so correct me if am i wrong.
For a school project i need to make technical study's more interesting for children.
And i had an idea to let them make a small USB powered fan, i found on the internet that you get around 5V from a normal USB. But my question is if this works the same for a mini USB, for use in tablet's and phones. So dose this cable put out enough power to maybe power a small fan, and dose this even work in general. I hop my question is clear and someone can help me with it.
I hope you can read it, English is not my best language;-)

Thanks

5V at 100mA is the standard 'allowance' for USB ports, though some are capable of significantly higher current

such be enough to drive a small 6V fan

you might want to place a diode [reversed] across the fan to suppress back EMF.
