kLite Minimalist Dynamo to USB Charging Kit - SON Hub
You're a minimalist at heart, and are interested in lugging the smallest amount of kit when you're in the backcountry. You love the idea of riding with a dynamo for the awesome feeling of self sufficiency it provides. But your riding ends well before the sun goes down, and you'd rather trade off the benefits of a dynamo light for a lighter overall load on your bike. You really just want a way to charge your devices when you're riding, and you don't want to mess with the complexity of integrating a whole system on your bike.
Enter the kLite Minimalist Dynamo Charging System. The kit includes a kLite Dual USB Charger, a Minimalist unswitched wire loom (33 inches in length) that connects the USB charger to your SON or Shimano / SP dynamo hub, and zip ties to connect the wire loom to your bike. The system will take you minutes to configure and before you know it, you'll be converting the 3W variable voltage alternating current from your dynamo hub to two controlled streams of 5V DC from the Dual USB Charger.
The USB charger has a red LED indicator lamp that glows when current is flowing into the device, giving you that "warm fuzzy" feeling that comes from knowing that everything is working like it should. Mount the device in a convenient cockpit location and you'll have a stream of USB power whenever your wheels are turning faster than 8MPH. The device is weatherproof but you'll want to avoid tons of mud since it can jam up the USB ports, so it's best to keep it out of the direct wheel spray. Some prefer to keep it inside their top tube bag, others mount it to the underside of the handlebar, the head tube or to the side of the top tube. Minimalists like yourself will appreciate the mounting "system" - zip ties.
