Short of walking up the big hills for you, the Eton Scorpion has everything you could need for a trip into the wilderness. Modestly described as a multi-function radio, this rugged gadget can be powered by hand using a fold-out turbine handle, or (if that sounds like too much effort) an integral solar panel.
As well as running a host of typical analogue radio functions, all that hand-cranking or sun-baking will also power a built-in LED torch and a USB mobile phone socket. Completing this tough little wundergadget is a sturdy aluminium carabiner and a bottle-opener. Well... taking on nature can be thirsty work.
