3. Setup
- Extend the Cable: Gently pull both ends of the cable simultaneously to extend it to the desired length. The cable will lock at various intervals. Do not pull only one side, as this can damage the retraction mechanism.
- Connect to Power Source: Plug the USB-A end of the cable into a compatible USB power adapter, computer USB port, or power bank.
- Connect to Device: Select the appropriate connector (Lightning, USB-C, or Micro-USB) and plug it into your device's charging port.

4. Operating Instructions
- Charging Multiple Devices: The MINLU Multi Charging Cable 4A allows you to charge up to four devices simultaneously. Connect each device to its corresponding connector. Note that the 4.0A total output is shared among all connected devices, which may result in slower charging speeds when multiple devices are connected concurrently.
- Data Transfer (Lightning Only): To transfer data or use Apple CarPlay, connect an iOS device to one of the Lightning connectors and the USB-A end to a computer or compatible car system. Data transfer is not supported by the USB-C or Micro-USB connectors.
- Retracting the Cable: To retract the cable, gently pull both ends slightly further until the locking mechanism releases, then allow it to retract slowly and evenly.

- Cleaning: Use a soft, dry cloth to clean the cable and connectors. Avoid using liquids or abrasive cleaners.
- Storage: Store the cable in its fully retracted state in a cool, dry place away from direct sunlight and extreme temperatures.
- Avoid Stress: Do not bend the cable sharply at the connectors or place heavy objects on it.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Cable not charging device. | Loose connection, incompatible power source, damaged cable/connector. | Ensure all connections are secure. Try a different power adapter or USB port. Inspect the cable and connectors for visible damage. |
| Slow charging speed. | Multiple devices connected, low-power USB port, device's charging limit. | Disconnect other devices to charge one at a time. Use a higher-amperage USB power adapter. Check your device's charging specifications. |
| Cable not retracting properly. | Improper retraction technique, internal mechanism issue. | Ensure you pull both ends simultaneously to release the lock. Avoid pulling only one side. If the issue persists, the mechanism may be worn. |
