Just for interest folks: As an experiment, I charged up the 505 via usb cable last night until the red light wasn't showing and the battery icon claimed a 'full' charge with four black cells showing. I then left the reader open without turning a single page. According to Sony claims, this should mean there would be zero drainage. However, when I woke up and checked this morning, the battery was as flat as a flapjack. I think those who recommend the AC charger are probably right. Sony is making false claims about the effectiveness of its 'free' usb cable. Many thanks. Neil
