7. Troubleshooting
If you encounter issues with your charger, refer to the following common problems and solutions:
- Charger not powering on or batteries not charging:
- Ensure the USB-C cable is securely connected to both the charger and the power source.
- Verify that your power adapter has an output of 22.5W or higher. The charger is not compatible with 5V/1A adapters.
- Check if the batteries are correctly inserted into the slots.
- Slow charging:
- If using a 5V/2.4A adapter, the charger will operate in slow-charge mode and prioritize Channel 1. This is normal behavior. For faster charging, use a 22.5W or higher power adapter.
- LEDs flashing red and white alternately:
- This indicates an overheating condition. The charger will automatically reduce charging speed until the temperature returns to a safe range. Ensure the charger is in a well-ventilated area.
- Charger stops charging unexpectedly:
- This may be due to over-voltage protection. Disconnect and reconnect the power source. If the issue persists, try a different power adapter.
