Hi Mikael

Apple frequently change the charging requirements with each new iPod model, so the manuafacturers of docking stations are always playing catch up. Full compatibility with this season's models could still leave any given docking device obsolete with next year's models.

This has been the case with the F80/i80. Originally, mine would charge my kids iPods, but not my own v5.5 Video iPod. After a visit to the factory for other reasons, I was delighted to see that they'd updated the iPod compatibility, and it charged my v5.5 iPod upon it's return. However, the iTouch which I got for Christmas isn't supported, so as Crion noted above, the supplied wall wart PSU needs to be used via the i80 USB input.

Cheers

George
