I am building up a commuter/tourer/general purpose bike with a hub dynamo.
From the hub dynamo I will want to run a front and rear light, and some sort of usb charging port for sat nav. I don't expect to be running lights at the same time as charging other stuff, so power drain shouldn't be a problem.
Anybody done this kind of setup? I would like to keep it as clean as possible. Is it possible to charge a Germin unit from the output of an exposure revo?
Are there any decent alternatives to the revo that are permanently wired and fixed?
