I Found these on the shelf at my local Poundland store in Gateshead.
A handy pocket sized gadget to pop into your bag as an emergency mobile phone charger when travelling - no need to rely on backup batteries or mains. Will fit Nokia (they've had them in stock previously with Samsung adaptors).
Here's the information from the packaging:-
* 3 minutes of winding gives 2-8 minutes of phone power
* 2 phone adaptors included for most mobile phone brands
* LED light shows when charging
