Technology has taken over our beloved bicycles, with the advent of modern navigation systems, tiny in size but with many useful functions. They have a big problem, however, in that they consume energy, batteries have a short life. Here's the perfect solution: combine a small transformer connected to a hub dynamo to charge your GPS system, cell phone or tablet.
We are experienced randonneurs, cyclotourists, and we have tried almost all GPS battery chargers available on the market. The ones that we offer in our store and online, are the most reliable and robust gps chargers currently available.
