UGREEN USB Bluetooth 5.0 Adapter (UG-80889, CM390)
The UGREEN USB Bluetooth 5.0 Adapter (UG-80889) is a compact USB-A dongle that adds Bluetooth connectivity to desktop PCs and older laptops without built-in wireless support. Built around the Realtek RTL8761BU chipset, it delivers Bluetooth 5.0 with EDR (Enhanced Data Rate), offering roughly twice the speed and up to four times the range of Bluetooth 4.0 devices, while remaining backward compatible with Bluetooth 4.2 down to 1.1 for older peripherals. At just 32mm x 16mm x 8mm and weighing 3.3 grams, it stays nearly flush in a USB port, making it practical to leave permanently plugged in without sticking out awkwardly on a desktop tower or laptop edge. It supports simultaneous connections to up to five Bluetooth devices, useful for anyone running a wireless keyboard, mouse, and headset from the same PC at once — a common setup in Nairobi home offices and shared workspaces.
