My tracker has been charged for a whole night, but the LED is still showing red, what can I do?
- Check if the adapter has 5V/0.5-1A output.
- Try again with a different USB adapter or socket.
- Turn off the device and charge it again.
- Using incompatible USB adapter, i.e. laptop USB port not supplying enough current.
- Fluctuation in current.
- Possible device fault.
