during the pc fair, i bought an iPod 30gb and they got free 1 thing and it is USB Power Adaptor. Can i use this USB Power Adaptor from Sonic Gear to charge my iPod?

I think it will work but if short circuit happens to that adapter or the adapter cause malfunction to your Pod, you might not get a warrantty claim. It's like using a China-brand charger...

Getting a Apple USB Adapter charger is much more safer....

when i bought the ipod they also free Apple USB Adapter but i seems the two head can't fit into it

Can show the head? If it is for iPod, I think it is all the same... Just don't force it in until you are really sure...
If you face problems, just take it to their shop... They might help you out with it...

no i mean the adapter. the adapter got 2 heads ma.....so that can plug in to the switch socket. but the 2 heads like to narrow and i can't fit it in the switch socket

Oh. As in the pins is it? Which looks like this?
\ / Not the round type right? Just go hardware shop and show the shopkeeper your adapter and ask them to give ya the adapter which can connect your adapter. Hope you understand.

lol...i certainly understand.
thanks.....
