UGREEN CM748 (45134) Bluetooth v5.4 Adapter

The UGREEN CM748 (45134) Bluetooth v5.4 Adapter is a compact USB‑A dongle that upgrades your PC or laptop with the latest Bluetooth 5.4 wireless connectivity, delivering faster data transfer, improved connection stability, and reduced latency compared with older Bluetooth versions — ideal for streaming audio, gaming, and peripheral use. With Bluetooth 5.4 technology at its core, this adapter provides a stable wireless link that supports multiple Bluetooth profiles such as A2DP, HSP, AVRCP, HID, PAN, and more, making it compatible with a wide range of devices such as headphones, speakers, keyboards, mice, and game controllers. The CM748 can connect up to five Bluetooth devices simultaneously without interference, though only one audio device will play music at a time, and its 20 m (≈65 ft) transmission range allows free movement within a room while maintaining reliable connections. Designed for plug‑and‑play convenience on Windows 10 and Windows 11, and requiring a free driver on Windows 8.1, this tiny adapter fits unobtrusively into a USB port without blocking adjacent slots, and its durable ABS build with LED status indicator adds both portability and practicality. Whether you want to add Bluetooth to a desktop without built‑in wireless or enhance an older laptop’s connectivity, the UGREEN CM748 offers a versatile and easy‑to‑use solution for modern wireless needs.
