  Ensure the USB cable is securely connected to both the charger and the power source. Verify that the batteries are inserted correctly with matching polarity. Try a different USB cable or power source.
• Short Battery Life:
  Battery life can vary depending on the device and usage intensity. Ensure batteries are fully charged before use. Over time, all rechargeable batteries experience a decrease in capacity. If battery life becomes significantly short, consider replacing the batteries.
