Product Overview

The UGREEN USB-A Bluetooth 5.4 Adapter CM748 adds wireless Bluetooth connectivity to compatible desktop computers and laptops. It is designed for Windows users who want to connect wireless headphones, speakers, keyboards, mice, and other supported Bluetooth devices.

Many desktop computers lack built-in Bluetooth, while some older laptops have limited wireless connectivity. This compact adapter provides a convenient way to add Bluetooth functionality through an available USB-A port. It helps users enjoy wireless audio and connect compatible peripherals without installing a separate internal card.

Bluetooth 5.4 technology supports efficient wireless communication with compatible devices.

Actual functionality depends on the connected device, operating system, and supported Bluetooth profiles.

Its small form makes it suitable for home offices, workplaces, study areas, and entertainment setups. Once connected to a compatible computer, users can pair supported accessories through the Windows Bluetooth settings. This creates a practical wireless workspace with fewer cables and greater flexibility.

The CM748 is particularly useful for people upgrading an existing computer without replacing the entire system. It offers a straightforward solution for everyday wireless connectivity, from listening to music to using a Bluetooth keyboard.

Why Choose the UGREEN CM748 Bluetooth Adapter?

Modern Bluetooth 5.4 Connectivity

Bluetooth 5.4 provides a modern wireless connection for compatible computers and accessories. It supports communication with compatible devices using earlier Bluetooth versions.

This makes the adapter useful for connecting existing peripherals without requiring every accessory to support Bluetooth 5.4. Users can pair compatible headphones, speakers, and input devices through their computer’s Bluetooth settings.

Wireless performance depends on the connected accessory and its supported profiles. The adapter provides the connection interface, while the computer and peripheral determine the available features.

Connect Multiple Bluetooth Devices

The CM748 supports connections with up to five compatible devices simultaneously. Users can combine a wireless keyboard, mouse, headphones, and other supported peripherals in one setup.

This flexibility helps reduce cable clutter on desks and workstations. It also allows users to organise their workspace around their preferred accessories.

Connecting multiple devices does not mean multiple audio outputs can play simultaneously. Only one Bluetooth audio output should be expected to play at a time.

Compact and Convenient Design

The small USB-A dongle fits directly into a compatible computer port. Its compact construction makes it easy to carry between home, office, and study environments.

Users can leave it connected during normal operation or remove it when transporting their computer. Since it draws power from the USB port, there is no separate battery to charge.

Its straightforward design makes it suitable for everyday computer upgrades without complicated hardware installation.

Simple Windows Setup

The adapter supports plug-and-play operation on Windows 11, Windows 10, and Windows 8.1. Windows 7 users need an appropriate driver for compatibility.

Once recognised, the adapter allows users to pair supported accessories through Windows Bluetooth settings. This makes connecting wireless peripherals accessible to users without advanced technical knowledge.

Applications and Professional Use Cases

Home Offices and Business Workstations

Professionals can connect Bluetooth keyboards and mice to compatible desktop computers. Wireless headphones also support private listening during virtual meetings and focused work sessions.

Reducing cable clutter can help create a cleaner workstation. Employees can arrange their equipment more comfortably while retaining access to supported wireless peripherals.

Entertainment and Audio Streaming

Users can connect compatible Bluetooth headphones and speakers to a Windows computer. This allows wireless listening during music playback, video streaming, and other supported audio applications.

Audio quality and latency depend on the connected device and supported Bluetooth profiles. The adapter does not guarantee specific premium codecs or identical performance across all headphones.

Students and Everyday Computer Users

Students can use the CM748 to connect compatible wireless accessories to desktop computers that lack Bluetooth. A wireless keyboard or mouse can make everyday study activities more convenient.

It also supports compatible headphones for online learning and personal entertainment. Users should confirm that their preferred accessories are supported by their computer’s operating system.

Gaming and Technical Workstations

Compatible game controllers can connect to supported Windows computers through the adapter. This offers another option for users who prefer wireless controller operation.

IT technicians can also use it to add Bluetooth connectivity to suitable office computers. However, direct use with gaming consoles is not supported, and peripheral compatibility should be checked before purchase.
