Description
The Poly USB-A to USB-C Adapter (85Q48AA, part 209505-01) converts a USB-A headset connection to USB-C, allowing Poly headsets with USB-A connectors to plug into devices that only provide USB-C ports — such as modern laptops and docking stations that have eliminated USB-A entirely. TAA compliant for US federal procurement, it is a small, lightweight adapter that keeps in the laptop bag alongside the headset cable.

- TAA Compliant: Meets US federal and government procurement requirements.
