Hi guys, I just got my hands on a lovely Pre, and I've discovered that the Pre comes with a micro-usb adaptor wall charger....

Now I've got a Cowon s9 mp3 player that also charges via USB only, can I now connect my mp3 player USB cable to the Pre's adaptor and charge via socket??

Only asking in case someone else has tried it, I don't want to risk damaging my 200 mp3 player..
