USB interface uses the innovative double-sided design, regardless of the pros and cons, double-sided available, without fear inserted backwards. PVC transparent outer protective wire, enameled inner double protection, tensile, bending, effective protection. High-purity oxygen-free copper wire core, conductivity better ensure the integrity fast transmission of data signals. Using the plating process, the conductive reduce impedance, increasing the signal transmission. Maximum support 2.1A of current through the plug and charge, charging and fast data transmission combo, and convenient.
