It uses a Realtek chip to enable wireless pairing with headphones, speakers, keyboards, mice and game controllers. The adapter measures 1.06 inches long and weighs 3 grams.

USB interface and Bluetooth 5.4 limits

The adapter plugs into a standard USB port and delivers data rates up to 3 Mbps, double the throughput of Bluetooth 4.2. It supports dual‑mode BR/EDR and Low Energy operation for broader device compatibility. A clear line of sight yields a wireless range of roughly 20 meters. The dongle can maintain up to five simultaneous connections without interference.

Check your system before ordering

Verify that the computer runs Windows 11, 10, 8.1 or 7; Windows 7 requires a driver download. The adapter does not work with Mac OS, Linux, car stereos, televisions or game consoles such as PlayStation, Xbox or Switch. Disable any built‑in Bluetooth radio in Device Manager to avoid conflicts.
