Hi I have just bought a Tom Tom One gps device (found it great in use) but need some advice on charging. It comes with an in-car charger and it's possible to buy TomTom's own "Indoor" charger. However, I have a Hama USB charger that I use to charge my MP3 player (Mains to USB) and what I would like to know is can I use this for the GPS ? According to the Hama website, this device will charge any USB device upto 500ma, but I cannot find anywhere what the GPS is rated at. Any help would be more than welcome. Thanks in advance FBG40
