UGREEN Bluetooth 5.3 USB Adapter for PC

Wireless Freedom for Any PC, Instantly

Bring reliable Bluetooth connectivity to any desktop or laptop that's missing it. Built around Bluetooth 5.3 with an integrated high-sensitivity antenna, this compact USB dongle delivers a stable signal up to 20 meters in open space, with a max RF output of 4dBm (EIRP) across the 2.402–2.480GHz band — enough range and stability to keep a wireless keyboard, mouse, or headset connected without the stutter that plagues older adapters.

Rather than juggling one device at a time, this adapter connects up to 5 Bluetooth devices simultaneously, so a mouse, keyboard, speaker, and headset can all stay paired at once. It supports a wide set of Bluetooth profiles (A2DP, HSP, AVRCP, HID, PAN, GAVDP, DID, IOPT), covering everything from audio streaming to input devices and file transfer, with a status LED that shows connection state at a glance.

Setup is plug-and-play on Windows 8.1, 10, and 11 — no external battery or charging needed since it draws power directly from the USB port. Its small footprint means it can stay plugged in permanently without blocking neighboring ports. Note: this adapter is designed for Windows PCs and does not support Apple devices.
