“Geek” and “Hardy outdoor adventurer” are not two phrases that usually share a paragraph. Nevertheless these rucksacks from Voltaic are practical as well as being cool and high tech so I can see them being bought by both groups.

Nah - who am I kidding, they’re a geek toy through and through! The idea is simple: Tech toys eat power, and we have lots of them. So… put some solar panels on a rucksack and voila, no charging worries.

The bags aren’t man enough to power a laptop but Voltaic claim it’ll recharge your GPS, PDA, phone, MP3 player and doubtless many other small electronic devices. Oh, and they’ll hold a change of clothes too if you really want…

The bags come with adapters for just about everything you can imagine: various makes of phone, GPS, PDA and also AC adapters to charge the bag(!) from a car or other power source when you’re not in the sun.
