Introduction of magnetic charging line: The magnetic charging line is also known as a magnetic data cable, magnetic charging cable, or magnetic USB charging cable. It consists of a pin needle, magnet, and plastic housing structure. Charging is conducted internally via pogo pins, supporting both signal transmission and charging functions. Advantages of magnetic connectors: (1) Humanized design with automatic magnetic attachment for easy operation (2) Secure magnetic connection that resists accidental disconnection and prevents device drop (3) Long service life (4) Waterproof design; the female connector provides dustproof and waterproof protection (IPX8 rating) (5) Space-saving design; the female end supports pogo pin and SMT DIP jumper connections for PCB integration (6) Fast charging capability (7) High corrosion resistance (tested 48H–120H), suitable for harsh environments Specifications: Smart bracelet watch magnetic USB charging data cable 2-pin universal smart watch charging cable Compatible with: Universal 2-contact smart bracelets, children's watches Q12/S12/S2/Q15, and other waterproof models Contact pitch: 7.62 mm Cable jacket material: Black/White environmentally friendly rubber compound Electrical testing: 100% tested Package included: 1 x Charging cable
