USB-C Data Blocking Adapter Unitek A1055ABK01 — USB-C male to female, data-blocking connector

Unitek USB-C data blocking adapter A1055ABK01 is a compact USB-C male-to-female connector engineered to allow power delivery while preventing data transfer. The adapter fits between a USB-C cable and a charging port to ensure only power pins are connected; USB data lines are physically blocked. This accessory is intended for scenarios where you need to charge laptops, phones or tablets from public or untrusted USB-C ports without exposing device data or enabling unauthorized file access.

Advantages

The adapter provides a straightforward hardware solution for charging security: it permits standard USB-C power delivery while eliminating the possibility of data exchange. Its small form factor makes it portable and easy to carry with charging cables or power banks. Because it relies on physical blocking of data lines rather than software controls, it works independently of device settings and operating systems.

Suitable for

• Charging laptops, smartphones and tablets from public USB-C ports
• Using charging stations, airport or hotel USB-C outlets
• Preventing data theft or unauthorized access when using shared chargers or kiosks
• Connecting power banks or USB-C chargers where data transfer is not required

Key specifications

• Connector type: USB-C male to USB-C female with data-blocking function
• Functionality: allows power delivery (charging) while blocking USB data lines
• Compatibility: works with devices that charge over USB-C and chargers/power banks providing USB-C power delivery
• Form factor: compact, inline adapter suitable for travel and daily carry
• Operating principle: physical interruption of data conductors, no software required

How to use

Connect the adapter to a USB-C charging cable or directly into a USB-C port on a charger or power bank. Then plug your device’s USB-C cable into the adapter’s female end. The adapter permits power delivery through the cable while preventing any data lines from establishing a connection between the charging source and the device. No setup, drivers, or configuration are needed.

Usage recommendations

Use the adapter whenever you charge from public or untrusted USB-C sources to reduce the risk of data exposure. Confirm that connectors are fully seated to ensure reliable power delivery. The adapter is designed for charging only; do not expect data synchronization or tethering while it is in use.
