Features：
USB-A Data Blocker prevents accidental and/or malicious data exchange when your device is plugged into someone else’s computer or a public charging station. The USB Data Blocker achieves this by blocking the data pins on any USB cable and allowing only power to flow through. This minimizes opportunities to steal your data or install malware on your device.
Our USB Data Blocker works with any device: Android, iOS, Samsung, Windows, etcetera.
