Troubleshooting
If you encounter issues with your AOHI Magcube charger or cables, refer to the following common solutions:
- Device Not Charging:
- Ensure the charger is securely plugged into a working wall outlet.
- Verify that the charging cable is firmly connected to both the charger and your device.
- Try a different port on the charger.
- Test with a different compatible cable to rule out cable issues.
- Check your device's charging port for any debris.
- Slow Charging:
- Ensure your device supports fast charging and that you are using a compatible cable (e.g., USB-C to USB-C for PD charging).
- If charging multiple devices, the power output per port may be reduced. Try charging a single device.
- Some devices, like certain Dell laptops, may have protocol restrictions that prevent full-speed charging.
- Data Storage Not Detected (Magflash Cable):
- Ensure you are using the short Magflash cable, as only this cable has the storage function.
- Verify the cable is securely connected to your computer's USB-C port.
- Try connecting to a different USB-C port on your computer.
- Restart your computer and try again.
- Charger Overheating:
- It is normal for the charger to become warm during operation, especially during fast charging.
- If it becomes excessively hot, disconnect it immediately and allow it to cool down. Ensure it is used in a well-ventilated area.
