Description

StarTech USBSCHAU1M USB Data Blocker Cable

Overview

The StarTech USBSCHAU1M is a 3.3 ft (1.0 m) USB-A to Micro-B cable designed specifically to prevent data transfer while allowing charging. This is critical for public charging stations, shared workstations, or any scenario where you need to charge a device without risking data compromise or malware injection. The 22/32 AWG wire gauge supports up to 2.4A of charging current, delivering 12W of power, ensuring efficient charging for compatible devices. The cable features a TPE jacket for flexibility and durability, with an aluminum-mylar foil and braiding shield to minimize electromagnetic interference, ensuring clean power delivery.

Compatibility

This cable is compatible with any device featuring a USB Micro-B port that requires charging. It functions as a standard USB charging cable but actively blocks data pins (D+ and D-). This makes it suitable for charging smartphones, tablets, portable power banks, and other USB-powered peripherals when connected to a USB power source like a wall adapter, car charger, or public USB port.

Installation Notes

No installation is required beyond plugging the cable into a USB power source and the target device. The operating temperature range is -20°C to 60°C (-4°F to 140°F), suitable for most indoor and vehicle environments.
