Overview

The Monoprice 112239 USB 2.0 Fast Charge Security Cable is built around one standout feature: a physical switch that disconnects the data lines inside the cable while keeping the power lines active. This means you can plug into an airport kiosk, hotel USB port, or any unfamiliar charging station and know that your device is only receiving power — no data can be read or malware pushed through the connection. Flip the switch back, and it functions as a normal USB 2.0 data and charging cable.

The cable itself is 4.5 feet long with a USB Type-A to Micro USB configuration and uses 30 AWG data wires paired with thicker 20 AWG power wires to support fast charging. It is a straightforward, inexpensive security tool for anyone who charges devices on the go and wants peace of mind without carrying a separate USB data blocker dongle. The main limitation is its Micro USB connector, which restricts it to older devices as the industry has largely moved to USB-C.

Frequently Asked Questions

It physically disconnects the data pins inside the cable while leaving the power pins connected, so your device charges normally but cannot exchange data with the host USB port — preventing unauthorized access.
Yes. When the switch is set to the "on" position, the cable functions as a standard USB 2.0 data and charging cable.
It connects a standard USB Type-A plug to a Micro USB connector, so it works with any device that charges or syncs via Micro USB.
No. The cable uses 20 AWG power wires for fast charging, and disabling data does not reduce the power delivery to your device.
