USB-A Data Blocking Adapter Unitek A1056ABK01 — USB-A connector, data-block function

The Unitek USB-A data blocking adapter A1056ABK01 is a compact accessory that allows USB-A power charging while preventing any data transfer between a host (PC, kiosk, charger) and a connected device. Designed to physically disconnect data pins inside the USB-A interface, the adapter provides a safe way to charge phones, tablets and other USB-powered devices from public or unfamiliar USB-A ports without exposing device data or enabling unwanted connections.

Advantages

This adapter provides a straightforward hardware-level data-block function that requires no software, drivers or configuration. Its small form factor makes it easy to carry in a pocket, wallet or travel bag. By isolating the data lines while leaving the power lines intact, the adapter reduces the risk of data theft, malware injection or unauthorized synchronization during charging. The durable USB-A connector is compatible with standard USB-A ports and supports typical charging currents of USB-A power sources.

Suitable for

• Charging smartphones and tablets at public charging stations
• Using kiosks, airport and train station USB ports
• Shared office or meeting-room charging points
• Travel and on-the-go charging where data security is a concern

Key specifications

• Connector type: USB-A male to USB-A female form factor for inline use
• Function: physical data-line blocking while allowing power delivery
• Compatibility: works with devices that charge via USB-A power ports
• Construction: compact, lightweight housing designed for portability
• Power handling: supports standard USB-A charging currents (subject to the host charger capabilities)

How to use

Insert the adapter into a USB-A power source, then plug the device’s USB cable into the adapter. The adapter blocks data communication automatically, so no setup is required. To resume normal data transfer, remove the adapter and connect the device directly to a trusted USB port or use a cable without the adapter. Inspect the adapter and connectors periodically for wear or damage and replace if physical defects are present.

Usage recommendations

Use the adapter when charging from public or unknown USB-A ports to minimize exposure of personal data. For firmware updates, data synchronization or trusted file transfers, connect devices directly to verified computers or use secure cables and connections that allow data exchange.
