A USB Type-C Data Blocker is a small device that acts as a barrier between your USB Type-C cable and the device you're connecting to, like a public charging station. It physically blocks data transfer while still allowing power to flow through, essentially converting the connection into a power-only connection.
 
Main Uses:
Protection Against "Juice Jacking": Juice jacking is a type of cyber attack where malicious charging stations or cables steal data or inject malware into devices while charging. By blocking the data lines, the USB Data Blocker prevents unauthorized access to your device's data.
Secure Public Charging: When you're in places like airports, hotels, or coffee shops, public charging stations could potentially be tampered with. A USB Data Blocker ensures that even if the port is compromised, no data can be transferred between your device and the charging station.
Privacy and Security: For those concerned with privacy and security, a data blocker offers peace of mind that only power will be transferred during charging sessions, protecting sensitive data on the device.
 
How it Works:
USB connectors typically have separate pins for power and data. A data blocker disables the data pins, allowing only power to pass through, thus providing a "charge-only" functionality.
In summary, a USB Type-C Data Blocker is a useful tool to safely charge devices in public or unfamiliar locations without risking data theft or malware attacks.
