Another common name for a USB adapter is a USB dongle.

Quick Scoop

When people say “USB adapter,” they might also call it:

  • USB dongle (most common alternate term, often used in textbooks and quizzes).
  • USB converter (especially when it changes one USB type to another, like USB‑C to USB‑A).
  • USB hub (when it’s a multi‑port adapter that expands one USB port into several).
  • USB connector, USB extender, or USB expansion port (less common but still used to describe similar devices).

A simple way to remember it: if it’s a small plug‑in device that adds a connection or feature through USB, calling it a “USB dongle” will almost always be understood.
