I bought a power to USB adapter, it plugs into the wall and has a usb socket.
You plug your usb cable it it and the device in question and it charges them. After all, all usb devices are 5v.
It works on everything I have (pda, ipod) - but not on my 505 - it actually manages to drain the battery of the 505! Any ideas what is going on here? This was supposed to be my charging solution on holiday, but so far it's a no go!
What have Sony done to the usb and/or firmware to stop it charging from the usb? Do we suspect it is done on purpose so you have to pay their fee for a mains charger?
