- Retractable USB-C Cable (PD30W Max): Connect your USB-C compatible devices (e.g., iPhone 15/16 series, Samsung Galaxy, Pixel, iPad Pro/Air/Mini, Switch, Macbooks) to this cable for fast charging.
- Retractable iOS Cable (5V/2.4A): Connect your Apple devices (e.g., iPhone 14/13/12/11/X series, older iPads, AirPods) to this cable.

Note: This car charger is designed for charging purposes only and does not support data transfer or CarPlay functionality.

Monitoring Car Battery Voltage
The integrated voltage display provides real-time information about your car battery's health:
- Normal Voltage: Typically between 12V and 14.8V when the engine is running or healthy.
- Low Voltage: A reading below 12V may indicate a weak or failing car battery, or an issue with the vehicle's charging system. It is recommended to have your car battery checked if consistently low readings are observed.

Maintenance
To ensure the longevity and optimal performance of your SUPERONE Retractable Car Charger, follow these maintenance guidelines:
- Cleaning: Use a soft, dry cloth to wipe the exterior of the charger. Do not use liquid cleaners or abrasive materials.
- Cable Care: Always retract the cables gently. Avoid yanking or forcing the cables, as this can damage the retraction mechanism. Ensure cables are fully retracted when not in use to prevent tangling and damage.
- Storage: When not in use for extended periods, store the charger in a cool, dry place away from direct sunlight and extreme temperatures.
- Connection: Periodically check the connection to the cigarette lighter socket to ensure it remains firm and free of debris.
