Possible Reasons:
- Loose or damaged data cable
- Dirty charging port
- Faulty battery/charging circuit
Solution:
① Cable Replacement
Replace the USB cable and charging head to charge the BN002, and observe the indicator light or battery level changes.
② Charging Port
Cleaning: Gently wipe the inside of the USB port with a dry cotton swab to remove dust, ensuring the plug is fully inserted.
③ Ambient Temperature
Charging efficiency may be low in environments below 0°C.
Move the device to room temperature and try again. If still ineffective, it is likely a hardware issue.
If the problem cannot be solved still, please contact the manual support.
