The design inspiration of this lanyard data line is derived from the current young people's dual pursuit of "pragmatic EDC portable culture", which upgrades the traditional data line from a single functional accessory to a portable equipment with both use value and trend attributes. It draws on the modular design language of tactical lanyard and key chain, combines the data line with the mobile phone anti-loss lanyard into one, realizes the function of directly mounting on the mobile phone through the structure of T-shaped anti-loss piece, metal hanging ring and woven rope, and solves the pain point that the data line is easy to lose and difficult to find. In appearance, the contrast color design of functional wind is adopted, and the metal joint is matched with high-density braided rope to strengthen the tough outdoor feeling. At the same time, through the double-specification interface design of Type-C to Type-C and Type-C to Lightning, the charging needs of apple and Android users are taken into account, making it not only a daily emergency charging wire, but also an ornament for individual wearing, perfectly suitable for commuting, outdoor and other multiple scenes.
