USB from headlight?

[Cyklefanatic]

Is it possible to wire a USB cable to a 6 volt ebike headlight so that you can charge your phone as you ride?

Sure. Are you comfortable with wiring? Stick with a low output i.e. usb 2.0 (1.5-2A) unit so you don't melt your tiny light wires with too much draw. Also make sure the unit you order has an input range below 6V or it may drop out if the voltage isn't steady. https://www.amazon.com/DaFuRui-Conv...PEQMXSD2GWF&psc=1&refRID=3WZZWM69RPEQMXSD2GWF

Some motorbike guys with 6V systems also just plug in the battery tender USB plug kits and report reasonable performance, but since they are feeding them 8+V when the bike is running, it may or may not work with less than 6V. https://fortnine.ca/en/battery-tend...NrWNl8lW1w6J5yhZm0aYb4Ee8w0wU3XwaAjehEALw_wcB
