The USB Type A (ST) to C (BU) data blocker adapter stops the data lines of the used USB port, thus protecting your mobile device, such as your smartphone, from unwanted access or malware, as only power can be transmitted. This is particularly useful in unfamiliar environments where USB ports can be easily tampered with or hijacked, such as in hotels, airports, or train stations. It prevents your device from becoming a target for attacks through foreign USB ports, thereby reducing the risk of malware being transferred to your device. Suitable for charging mobile devices in any hotel or other public environments, such as schools, museums, trade fairs, or other locations. It is also ideal for anchor points like airports and train stations. It does not cause any conflicts with the existing IT infrastructure. It prevents data exchange by blocking the data lines - only power is transmitted to your device. Safe charging without complications.
