Protect your devices while charging from public or untrusted USB ports with the STS USB A/C Data Blocker Charge-Only Privacy Adapter.

It is available in multiple connector styles, including USB-C to USB-C, USB-A to USB-C, USB-C to USB-A, and USB-A to USB-A, making it easy to match your existing cables and devices.
