What to Do If the AC Charging Fails

1.Verify Charger Voltage (Crucial)

• Action: Check the specifications of your power adapter. The device requires a 5V/2A power adapter.

• Warning: Do NOT use a 12V power supply with the USB port, as this will burn out the internal charging circuit. Damage caused by improper use is not covered under warranty.

  2. Cross-Test with Different Accessories

  • Action: If the device fails to charge, try using a different 5V/2A adapter and a different charging cable to rule out a faulty charger or cable.

3. System Reset (For Firmware Issues)

• Action: If the hardware connection is fine but there is no response, the firmware may be frozen. Open the waterproof rubber plug and long-press the Reset button for 10 seconds.

  

• Observation: Check if there are any voice prompts or flashing lights. If the device responds, try charging it again.

4. Contact Technical Support

• If the issue persists after following the steps above, please contact customer support with the following:
  • Your device NID (and ICCID for 4G mode users).
  • A video recording: Show the status of the indicator lights while the device is plugged in for our engineers to review
