6. Maintenance and Care
To ensure the longevity and optimal performance of your charger cable, please observe the following care guidelines:
- Regularly clean the charging pins and magnetic surfaces to prevent the accumulation of dust or debris, which can interfere with proper contact.
- Avoid sharp bends or kinks in the cable, especially near the connectors, to prevent internal wire damage. The cable is constructed with flexible PVC material and has undergone durability testing (over 6000 bends).
- Store the cable in a dry environment when not in use.
- Do not expose the cable to extreme temperatures, direct sunlight, or liquids.
