6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger LED is off. | No power supply; charger not connected to device; device battery fully charged. | Check power outlet and connections. Ensure charger is properly plugged into both the wall and the device. If battery is full, LED will be green. |
| Red LED is on, but battery is not charging. | Incorrect connector; faulty battery; charger malfunction. | Verify the correct connector is used and securely attached. Test with another compatible device if possible. If problem persists, contact support. |
| Green LED is on, but battery is not full. | Battery issue; charger issue. | Ensure the battery is not already full. If the battery is not charging to full capacity, the battery itself might be faulty. |
| Charger gets hot during charging. | Normal operation; poor ventilation; overload. | A slight warmth is normal. Ensure adequate ventilation around the charger. If it becomes excessively hot, disconnect immediately and contact support. |
This charger is equipped with multiple protection features including overvoltage, overload, overcurrent, and short-circuit protection to prevent damage to your device and the charger itself.
