More and more bikers are using their cell phones as navigation devices — thanks to Google Maps. Nobody worries about permanent transmission of location data 'cos after all, you have a flat rate with 50 Mbit/s of download speed. But one thing is clear: using your smartphone as a sat nav permanently drains the phone's battery and can work effectively only if you hook it to a charger on your Harley.

For all those who do not own a FLHTCU with a built-in USB port, this practical USB socket could be used to charge the cell phone. The socket is waterproof (as long as not in use!) and is mounted on the handlebars, the 12V/5V voltage converter and the 12V supply cable can be tucked away under the gas tank. Connection options are available at the battery terminals or on live wires — haha — via the supplied connectors.

Of course, the socket also charges the smartphone if it does not have to work as a navigation system.
