The JSAUX USB Data Blocker is a compact security accessory designed to help protect your devices when charging through public or unfamiliar USB ports in airports, hotels, cars, coworking spaces, and other shared environments. Its charge-only design blocks USB data transmission while allowing electrical power to pass through, helping reduce exposure to unauthorized data access, unwanted file transfers, and potential juice jacking attacks. Because the protection works at the hardware level, no software installation or configuration is required, and it helps prevent data synchronization prompts when connected to compatible charging sources. Supporting charging currents of up to 2.4A, it is suitable for compatible smartphones, tablets, and other USB-powered devices, although actual charging speed depends on the power source, cable, and connected device. The durable aluminum body and compact dimensions of approximately 30 x 10 x 10 mm make it easy to carry in a pocket, wallet, or travel bag. With four blockers included, this pack offers a convenient way to add a layer of protection to everyday charging routines. It does not guarantee protection against every USB-related threat, and charging compatibility may vary by device and connector type.
