When everything's flat, wind up a little power.
Dynamo is a pocket-sized hand-crank generator. Turn the handle and it sends power to your phone by USB — enough for an emergency call or message.
No socket needed
A dead phone, and no way to charge it.

Stranded with no battery left.
Power cut

Forgotten in a drawer for months.
Off-grid trips
Camping and hiking far from power.
Turn. Charge. Call.
