AJMRTC 65W DC 5.5x2.1mm Barrel Jack Charging Conversion Cable, 15V-24V Input to 20V Output Power Cord for Microsoft Surface Pro 3 4 5 6 7 8 9, Surface Book Pro Charger Adapter Cable

AJMRTC charging conversion cable is a handy power accessory designed for Microsoft Surface devices. It connects to adjustable bench power supplies or other DC power sources with a 5.5x2.1mm output port, converting 15V24V DC input into the proper charging signal for Surface Pro and Surface Book Pro models. It reaches up to 65W power capacity to meet the original charging power requirement.

Equipped with a built-in intelligent control chip, this cable stabilizes the charging voltage and current and suppresses sudden voltage surges. Comprehensive safety protections automatically cut off power when overvoltage, overcurrent, short circuit or excessive temperature occurs, protecting your Surface battery and motherboard from damage. The outer cable jacket uses high-flexibility PVC material, which resists wear, aging and cracking after repeated twisting and plugging. The molded strain relief at both ends strengthens the connection and prevents internal wire fracture.

This cable is perfect for electronics repair technicians, lab testing and DIY power projects. It offers a convenient charging and troubleshooting option when the original Surface charger is missing. Important Note: Your DC power supply must provide steady and sufficient current for normal charging. Inadequate current output will cause slow charging or no charging.
