Bluetooth 5.3 Technology

The UGREEN 90225 uses Bluetooth 5.3, providing a modern wireless connection between your computer and compatible Bluetooth accessories.

Bluetooth 5.3 brings improvements in efficiency, connection management and wireless performance compared with older Bluetooth generations.

For everyday users, this can mean a smoother experience when using wireless audio accessories, keyboards, mice and controllers.

The adapter's Bluetooth frequency range is 2400MHz–2483.5MHz, while UGREEN specifies a transmission distance of up to 20 meters / 66 feet under unobstructed conditions. Actual range varies depending on walls, interference, computer placement and connected devices.

Connect Wireless Headphones and Speakers

Turn a compatible Windows desktop into a wireless audio workstation.

The UGREEN 90225 can be used to connect compatible:

• Bluetooth headphones
• TWS earbuds
• Bluetooth speakers
• Wireless headsets

This is particularly useful for desktop computers that do not have built-in Bluetooth.

For gaming, video calls and music, a Bluetooth connection can eliminate the need for an additional wired connection between your PC and compatible audio equipment.

Wireless Keyboard and Mouse Connectivity

The adapter isn't limited to audio devices.

You can also use it with compatible Bluetooth:

• Keyboards
• Mice
• Controllers
• Printers

Support for Multiple Bluetooth Devices

UGREEN documentation and product materials indicate support for connecting multiple Bluetooth devices, with product documentation describing simultaneous connections of up to several devices.

Actual simultaneous use depends on the devices, Windows Bluetooth stack, bandwidth and the type of peripherals connected.

This makes the 90225 useful for a complete wireless desktop setup.

---

Up to 20-Meter Wireless Range

The UGREEN 90225 is rated for a transmission distance of up to 20 meters / 66 feet in open, unobstructed conditions.

In a real home or office environment, the usable distance can be lower because of:

• Furniture
• Metal objects
• Wi-Fi interference
• Other 2.4GHz devices
• PC placement

For best performance, UGREEN recommends connecting the adapter directly to the computer rather than through a converter and reducing physical obstacles around the adapter.
