[KILLERKASPER]

I'm not sure if you read my thread a while back but I know that if you have a motorola V3 razor mobile phone then the charger works fine (as far as i've used it). The charger doesn't work in the AC jack but in the USB jack in the bottom, as long as you have the iriver set to USB charge then it works a treat. It's quicker than charging from a P.C/ MAC aswell. I believe that the conection is different via USB charge so i think it would probably be safer than sticking any old thing in the AC socket.
