Hello & Welcome to Just Answer,
Sorry to hear of any issue you are having with your device.
To help you with this issue, may I ask:
1) Was the device "in use" - in a vehicle - at the time this happened?
2) Have you tried connecting to an alternate power source yet, and if so, what power source was that?
3) Do you still have the USB cable - for connecting to a powered ON computer?
