It's a wind up!

Another great gadget that I have come across is a shower proof radio that you can power by the sun or you can wind it up. What makes it specially handy for walkers is the integrated high power torch and the ability to charge up other devices using the hand crank. You wouldn't want to carry this up a mountain, but if you were a camper I can see that it would be very useful. See www.gadgetsUK.com
