3. Setup and Usage
3.1 Extending the Cable
To extend the miniSync cable, grasp both ends of the cable and gently pull them simultaneously away from the central retraction unit. The cable will lock into pre-set lengths. Do not pull only one end or from the middle, as this can damage the internal mechanism.

This image illustrates the correct method for extending the miniSync cable: pull from both ends simultaneously to prevent damage to the retraction mechanism.

To extend the miniSync cable, gently pull both ends until it reaches the desired length. The cable can extend up to 25 inches.
3.2 Retracting the Cable
To retract the cable, pull both ends slightly further out until the locking mechanism releases. Then, allow the cable to slowly retract back into the central unit. Guide the cable gently to ensure smooth retraction.
4. Operating Instructions

Connect the micro-USB end of the miniSync cable to your compatible device (e.g., Eyoyo EY-028). Connect the standard USB-A end to a USB port on your computer. Your device should be recognized, allowing you to transfer data, such as files or firmware updates.
4.2 Charging
Connect the micro-USB end of the miniSync cable to your compatible device. Connect the standard USB-A end to a USB power adapter (e.g., wall charger, car charger, power bank) or a powered USB port on your computer. Your device will begin charging.

The miniSync cable facilitates seamless data synchronization and charging between your portable devices and computers.

The miniSync cable offers multiple adjustable lengths, allowing comfortable use of your device while it charges or syncs.

The miniSync cable supports high-speed USB 2.0 data transfers and efficient charging, providing up to 15W power delivery.
5. Care and Maintenance
- Proper Handling: Always pull both ends of the cable simultaneously when extending or retracting to prevent damage to the internal mechanism.
- Cleaning: Use a soft, dry cloth to wipe the cable and connectors. Avoid using harsh chemicals or abrasive materials.
- Storage: When not in use, ensure the cable is fully retracted and stored in a clean, dry place away from extreme temperatures.
- Avoid Kinks: While the cable is designed to be durable, avoid sharp bends or excessive force that could lead to kinks or internal wire damage.
