Secure USB-A Data Blocker Adapter

The STARTECH USBSCHAAMF is a USB-A male to female adapter that physically blocks data pins. It lets you charge smartphones, tablets and other battery-powered devices from public ports or untrusted hosts without exposing them to data theft, malware or spyware. It is aimed at security-conscious users in corporate, defence, government and education settings who need charge-only access.

Charge-Only Power Delivery Up to 12W

The adapter passes 5V at 2.4A for a maximum of 12W, so it comfortably handles typical phone and tablet charging. It works with your existing USB-A to USB-C, Lightning or Micro-USB cables. It runs out of headroom for devices that require higher voltages or negotiation protocols such as USB Power Delivery, and it cannot transfer any data at all.

Rugged TPE Housing With No Active Cooling

A compact black shell made of thermoplastic elastomer measures .70" x 1.30" x .50" and weighs .01 lb. Nickel-plated USB 2.0 connectors resist corrosion during frequent insertion. There are no moving parts, no fan and no power draw beyond the connected device, so operation is completely silent and adds negligible thermal load.

Questions about this item

Will this adapter still charge my phone when I plug it into an older USB 2.0 port on my laptop?

Yes, the adapter passes 5 V at up to 2.4 A (12 W max) through any USB 2.0 male host port while physically blocking the data pins.

How can I confirm the adapter is actually blocking data after I connect it?

Plug a USB-A cable into the female end and attach a phone; the device should show charging only with no file-transfer prompt or media-device enumeration on the host.

Does the package include a charging cable or only the blocker itself?

The box contains only the USB-A male-to-female adapter; you must supply your own USB-A to USB-C, Lightning or Micro-USB cable for charging.
