Operating Instructions
Follow these steps to charge your batteries safely and effectively:
- Insert Batteries: Insert one or more AA or AAA rechargeable batteries into any of the 8 independent charging slots. Ensure the positive (+) and negative (-) terminals of the battery align correctly with the markings on the charger.
- Automatic Detection: The charger will automatically detect the battery type (Ni-MH/Ni-Cd or Li-ion) and begin charging.
- Monitor Charging Status: Observe the LED indicator above each slot:
- For 1.2V Ni-MH/Ni-Cd batteries: The LED will flash purple during charging and turn solid purple when fully charged.
- For 1.5V Li-ion batteries: The LED will flash green during charging and turn solid green when fully charged.
- Remove Batteries: Once the LED indicator for a battery turns solid (purple or green), the battery is fully charged. Carefully remove the charged battery from the slot.
Typical charging times are approximately 4 hours for AA batteries and 2.5 hours for AAA batteries, though actual times may vary based on battery capacity and discharge level.

Maintenance
Proper maintenance ensures the longevity and optimal performance of your POWXS battery charger.
- Cleaning: Disconnect the charger from power before cleaning. Use a soft, dry cloth to wipe the exterior. Do not use abrasive cleaners or solvents. Ensure no liquid enters the charging slots.
- Storage: Store the charger in a cool, dry place away from direct sunlight and extreme temperatures. When not in use for extended periods, disconnect it from the power source.
- Handling: Avoid dropping the charger or subjecting it to strong impacts, as this can damage internal components.
Troubleshooting
If you encounter issues with your POWXS battery charger, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not powering on / LEDs not lighting up. | No power supply; faulty USB cable; faulty power adapter. | Ensure the USB cable is securely connected to both the charger and a working 5V/2A power source. Try a different USB cable or power adapter. |
| Battery not charging (LED not flashing). | Battery inserted incorrectly; battery is non-rechargeable or damaged; charger slot malfunction. | Re-insert the battery, ensuring correct polarity (+/-). Verify the battery is rechargeable and not damaged. Try the battery in a different slot. If the issue persists with multiple batteries in one slot, that slot may be faulty. |
| Batteries get warm during charging. | Normal operation; overcharging; poor ventilation. | A slight warmth is normal. If batteries become excessively hot, remove them immediately. Ensure the charger is placed in a well-ventilated area. The charger has built-in overheat protection. |
| Charging takes longer than expected. | Low capacity power adapter; high capacity batteries; deeply discharged batteries. | Ensure you are using a 5V/2A power adapter. Higher capacity batteries will naturally take longer to charge. Deeply discharged batteries may require more time for initial activation and charging. |
