While I was in Hong Kong last week I picked up one of these great little gadgets for about £2.50. It's a retractable cable which lets you recharge your P800 from a USB port on your laptop. I'm finding it very useful so far! Not only is it great when actually on the move, but simply having a second charger around the house is very useful (my phone charger lives near the front door so I don't forget my phone on the way out, but sometimes I need the phone at my Mac but it's low on power).
