What the product is and who it is for

The TelDaykemei USB Bluetooth 5.4 adapter adds wireless connectivity to desktop and laptop computers without the need to install any driver. It plugs into a USB 2.0 or 3.0 port and works immediately on Windows 8.1, 10 and 11. The device targets users who want to connect audio, input or mobile peripherals through a single compact dongle.

Who this suits and who should look elsewhere

This adapter suits anyone needing to pair headphones, speakers, keyboards, mice or smartphones with a PC that lacks built-in Bluetooth. It supports up to seven simultaneous connections and covers a 20 metre range in open space. Buyers who require Linux or macOS support should look elsewhere because the supplied driver-free operation is limited to the listed Windows versions.

The specification that decides fit

The decisive specification is the Bluetooth 5.4 dual-mode radio with low-energy support and Class 2 transmit power. It operates on the 2.402 to 2.480 GHz band with a receiver sensitivity of -86 dBm and maintains backward compatibility with Bluetooth 2.0, 3.0, 4.0, 5.0, 5.1 and 5.3 devices. If your peripherals use any of those standards the adapter will communicate with them.

Questions about this item

Should I pick the USB 2.0 or USB 3.0 port for this Bluetooth 5.4 adapter?

It supports both USB 2.0 and USB 3.0 interfaces; either port will work because the adapter only needs USB 2.0 bandwidth for Bluetooth traffic.

What does the 20-metre range mean when I use this Bluetooth 5.4 dongle at my desk?

The 20-metre figure applies to an open, barrier-free environment; walls, furniture and other 2.4 GHz devices will reduce the practical distance.

How does the Bluetooth 5.4 standard limit what I can connect to this adapter?

Bluetooth 5.4 is dual-mode and backward compatible with Bluetooth 2.0, 3.0, 4.0, 5.0, 5.1 and 5.3, so it pairs with virtually any Bluetooth peripheral.
