The charger should be protected splash water, or be quickly demountable rain without having to turn off the lights forcibly. Because most phones are not well protected splash.
On the charger are now 2x female connector available. If you would assemble male 1x female and 1x, the issue would be settled with Remove in the rain ... I'm building the device around and make there a 3,5 mm jack and jack off. So I can disassemble the unit when it is raining and simply plug together the 2 wires and the electrical connection is established, the light works.
The wiring diagram is wrong. The Dynamo connection is swapped with the lamp connection!
But otherwise the device will work. My cell phone (Samsung Galaxy S2) beeps already at about 5kmh! That's pace. Unfortunately, I have not tested whether the phone is really loaded. Will I still do. The battery, however, support in any case.
Oh: hub dynamo from Shimano.
