StarTech 3 ft USB-A to Micro-B Data Blocker Cable

Control what passes through the connection. This 3 ft USB-A to Micro-B secure charging data blocker cable is built for environments where charging is allowed but data transfer is not. By preventing data exchange, it helps reduce the risk of unauthorized syncing, malware introduction, and accidental access through USB ports. The short 3 ft length is ideal for close-range charging at kiosks, reception desks, classrooms, labs, and shared work areas. It keeps the cable run compact, which makes installations easier to manage and less exposed to tampering or unnecessary slack. For IT and security teams, this kind of cable is a practical control point. It supports power delivery to compatible Micro-B devices while maintaining a clear separation between charging and data pathways. That makes it a strong fit for regulated environments, public-facing deployments, and any workflow that requires charge-only USB access. When the requirement is simple — power without data — this cable gives you a direct, purpose-built option.
