This compact microadapter converts a USB Type-A port into a USB-C socket, letting you connect USB-C cables to older computers, laptops, and hubs that only have USB-A ports.

The adapter supports USB 1.1 and USB 2.0 data transfer (no USB 3.0 pins). It provides standard 5 V power at up to 1 A — note that USB-C power delivery negotiation is not supported since the host port lacks that capability.

Key Features

  • USB-A Male to USB-C Female – Plug into any USB-A port, connect a USB-C cable
  • Reversible USB-C Socket – No orientation required on the cable side
  • USB 2.0 Compatible – Supports data transfer up to 480 Mbps
  • Compact Form Factor – Minimal size, easy to carry

Ideal For

  • Connecting USB-C development boards to older computers
  • Using USB-C cables with legacy USB-A ports
  • Prototyping and bench testing with mixed USB connectors
Note: This adapter does not provide USB 3.0 speeds or USB-C power delivery negotiation. It is designed for 5 V / 1 A operation with USB 1.1 and 2.0 devices.

Jargon buster

Plain-language definitions for the technical terms used above.

USB 1.1
USB 1.1 is an older USB standard with much slower data transfer than USB 2.0 and later versions. Compatibility with it allows connection to very old computers, though data-heavy tasks such as video may be limited at that speed.
USB 2.0
USB 2.0 is a widely used wired standard for carrying both data and power between a device and a computer or other compatible host, with data rates up to 480 Mbps. It indicates the kind of port a device uses and that it should work with most modern and many older computers.
USB-C
USB-C is a small, reversible USB connector that can carry power, data and, on some devices, video over a single cable. The same connector can range from charging only to high-speed data, so the functions a given port actually supports vary.
