6. Setup Guide
- Unpack: Carefully remove the HOCO N34 charger from its packaging.
- Inspect: Check the charger for any visible damage. Do not use if damaged.
- Plug In: Insert the charger's EU plug into a compatible AC wall outlet (100-240V).
- Connect Device: Use a suitable charging cable (not included) to connect your device to either the Type-C or USB-A port on the charger.


7. Operating Instructions
- Single Device Charging: Connect your device to either the Type-C port for PD20W fast charging or the USB-A port for QC3.0 fast charging. The charger will automatically detect the optimal charging protocol for your device.
- Dual Device Charging: You can charge two devices simultaneously using both the Type-C and USB-A ports. When both ports are in use, the total output will be 5V/3A, distributing power between the connected devices.
- Charging Indication: Your device's screen will typically indicate that it is charging, often showing a battery icon or a fast charging notification if supported.
- Disconnecting: Once your device is fully charged, or when you wish to stop charging, safely disconnect the charging cable from your device first, then unplug the charger from the wall outlet.



8. User Tips
- For optimal fast charging, use high-quality cables that support the respective fast charging protocols (PD or QC).
- When charging two devices simultaneously, the total power output is shared, which may result in slightly slower charging speeds compared to single-port fast charging.
- The transparent design allows you to see the internal components; handle with care to avoid scratches or damage to the casing.
- This charger is ideal for travel due to its compact size and broad voltage compatibility (AC100-240V).
9. Care and Maintenance
- Cleaning: Disconnect the charger from the power outlet before cleaning. Use a soft, dry cloth to wipe the surface. Do not use liquid cleaners or aerosols.
- Storage: Store the charger in a cool, dry place away from direct sunlight and extreme temperatures.
- Handling: Avoid unnecessary drops or impacts to prevent damage to the internal components or the transparent casing.
10. Troubleshooting
- Device not charging:
- Ensure the charger is securely plugged into a working wall outlet.
- Check if the charging cable is properly connected to both the charger and your device.
- Try using a different charging cable or a different device to rule out cable or device issues.
- Verify that your device is compatible with the charger's output specifications.
- Slow charging:
- Ensure your device and cable support fast charging protocols (PD or QC).
- If charging two devices simultaneously, the power is shared, which can reduce individual charging speeds. Try charging one device at a time for maximum speed.
- Check for background apps or high power consumption on your device.
- Charger feels warm:
- It is normal for chargers to become slightly warm during operation, especially during fast charging.
- If the charger becomes excessively hot, unplug it immediately and discontinue use. Contact customer support if the issue persists.
