5. Setup
- Connect Power: Plug the power adapter into the DC input port on the back of the charger. Then, plug the other end of the power adapter into a standard AC power outlet (100-240V).
- Initial Power On: When the charger is plugged in, the LED indicators will briefly light up green, then turn off, indicating it is ready for use.
6. Operating Instructions
- Insert Batteries: Carefully insert 1 to 8 Ni-MH or Ni-CD AA/AAA rechargeable batteries into the charging slots. Ensure correct polarity (+ and -) as indicated on the charger.
- Charging Process: Once batteries are correctly inserted, the corresponding LED indicator for each slot will turn red, indicating that charging has begun. The charger will automatically detect the battery type and capacity to optimize charging.
- Charging Completion: When a battery is fully charged, its corresponding LED indicator will turn green. You can remove the fully charged batteries at this point.
- Using USB Output Ports: Connect your USB-powered devices (e.g., smartphone, tablet) to the two USB output ports (5V/2A) on the side of the charger. These ports can be used simultaneously with battery charging.
7. LED Indicator Light Meanings
The charger features clear LED indicators to show the status of each battery slot:
- Red On: Battery is currently charging.
- Green On: Battery is fully charged.

9. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| LED indicator is flashing red. | Non-rechargeable battery, defective battery, short circuit, or incorrect battery insertion. | Remove the battery. Ensure you are using only Ni-MH/Ni-CD rechargeable batteries. Re-insert the battery with correct polarity. If the issue persists, the battery may be defective. |
| Batteries are not charging (no red LED). | Charger not powered, batteries not inserted correctly, or batteries are already full. | Check power connection. Ensure batteries are fully seated and polarity is correct. If LEDs are green, batteries are already charged. |
| USB ports are not charging devices. | Device cable issue, device not compatible, or charger overloaded. | Try a different USB cable. Ensure your device is compatible with 5V/2A USB charging. Disconnect other devices to check for overload. |
