UGREEN CM390 (80889) USB Bluetooth 5.0 Adapter

The UGREEN CM390 (80889) USB Bluetooth 5.0 Adapter is a compact and efficient USB‑A dongle designed to bring wireless Bluetooth connectivity to desktops, laptops, and other USB‑enabled devices that don’t have built‑in Bluetooth or need an upgrade to a more modern standard. Using Bluetooth 5.0 with Enhanced Data Rate (BR+EDR) and Low Energy (BLE) technology, this tiny adapter offers faster pairing, improved stability, greater range, and reduced power consumption compared to earlier Bluetooth versions, making it ideal for streaming audio, syncing peripherals, and transferring data without bulky cables. It supports a wide range of Bluetooth profiles such as A2DP, HSP, AVRCP, and HID, allowing you to connect headphones, speakers, keyboards, mice, game controllers, and more simultaneously—up to five devices at once in some configurations—while maintaining a reliable connection within an approximate 20 meter (65 feet) range in open spaces. The CM390’s plug‑and‑play design makes it easy to use (especially on Windows 10 and later), and its ultra‑compact form factor means you can leave it plugged in without blocking adjacent USB ports or carry it with your laptop on the go. Built from durable ABS plastic with a small LED indicator for status feedback, this Bluetooth 5.0 adapter is a simple, affordable way to upgrade your PC’s wireless capabilities for everyday tasks like music playback, video conferencing, gaming, and file sharing.
