Sometimes a faulty USB jack, cable or charger could be the cause of trouble.
The easiest way to test the cable and charger is with a light that you know responds correctly:
- Plug it in, and slowly move the cable around near the plug on both ends of the cable.
- If the light does not respond or flashes because you’re moving the cable, try a different cable and/or charger.
If the charge and cable are good, but still not working on the light, examine the USB jack in the light.
- Is there any dirt in there? Can you clean it out with a toothpick, needle or pin?
- Is the USB jack physically damaged? You might be able to bend it back into shape and keep using it.
If you notice that the USB port is damaged or unresponsive with a working charging cable, please contact us for warranty support and we'll get you sorted out.
