Add Bluetooth 5.0 to USB-A devices

This low-profile adapter plugs into any USB 2.0 Type A port and instantly adds Bluetooth 5.0 wireless capability to a PC or laptop. It supports simultaneous connections with up to seven devices such as keyboards, mice, headsets and printers. Data transfers reach 3 Mbit/s and the Class 2 radio broadcasts up to 165 ft.

Low-profile build stays in the port

The adapter protrudes less than 3/16 of an inch from the USB socket so it can remain connected during transport or while docked. A USB 2.0 Type A connector ensures broad compatibility with existing laptops and desktops. Built-in security handles pairing, encryption and authentication without extra software steps.

Replaces missing or older Bluetooth radios

Computers lacking any Bluetooth hardware gain full wireless peripheral support with this single dongle. Systems limited to earlier Bluetooth versions upgrade to 5.0 LE+EDR speed and range. The jump is worth it when you need to connect multiple modern peripherals at once or require the 165 ft coverage.

Questions about this item

What does the Bluetooth 5.0 Class 2 rating mean for the practical range of this USB 2.0 Type A adapter?

The Class 2 rating gives a wireless range up to 165 feet (50 meters) in open space, with actual distance depending on obstacles and interference.

How much does this low-profile adapter protrude from a USB-A port, and will it block adjacent ports on a laptop?

It extends less than 3/16 inch (about five millimetres) from the port, so it rarely blocks neighbouring ports and can stay plugged in during transport.

What is the correct pairing sequence to avoid the common 'device found but won't connect' error with this adapter?

Insert the adapter, let Windows install the driver automatically, then put the target device into pairing mode before clicking 'Add Bluetooth device' in Settings.
