Plug this into your dynamo hub and then plug your GPS or iPhone or other USB-powered gizmo into this, and away you go... Brilliant new product from Sinewave Cycles (formerly Bright-Bike Labs) in Cambridge, MA, and which doesn't need a cache battery to keep your iPhone charging. Water proof, super lightweight - the perfect touring companion!
