Belkin-branded USB charger plug and cable and iPod nano case.
Ignoring the case for a moment, I paid 15 quid for the charger alone, which is a mains powered USB port essentially. I have used mine to charge mobile phones, friend's iPods, iPhones, my Creative Zen, my PSP, my Playstation wireless headset, an external hard drive, anything that charges from USB.
This is an absolute bargain, and every geek should have one.
In stock for home delivery and reserve and collect. Give the nano case to charity or a friend, and keep the awesome charger unit.
As an aside, my model of this charger is also in two parts, a US compatible plug and a secure but removable UK converter attached to it. If you want to use it in the states I imagine you just pull the UK section off the bottom and plug it in their foreign wall sockets. (I haven't tried this, so no promises).
Don't forget to Heat and Rep. :D
