How to Use & Care for Your Microsoft Surface Pro 36W 12V 2.58A Laptop Adapter?

• Check the Voltage: This unit is the 12V 2.58A version. If your Surface Book or Pro 9 requires 15V, we recommend our higher-wattage 65W or 102W HTJ models for faster charging.
• Secure Attachment: The LED on the connector should glow when attached. If not, wipe the magnetic pins with a dry cloth to ensure a clean connection.
• Portability Care: Use the integrated strap for coiling. Avoid wrapping the cable tightly around the brick to maintain the integrity of the internal copper shielding.
