Hand-cranked USB power charger
It's not exactly super portable, but this hand-cranked USB charger offers a new way to charge your phone or other mobile gizmo of choice without having to resort to the national grid.
Unlike solar chargers, this gadget will work at any time of day or night provided you've got a pair of hands to turn the handle. Great for camping and festival trips, it might just help you avoid those notorious 'chill and charge' tents this year!
$39.95 at National Geographic store
