  • TypeBluetooth Adapter
  • Bluetooth 5.1 EDR delivers four times the range of older versions
  • Connect up to 10 devices simultaneously including earphones
  • 3 Mbps transfer rate for fast data exchange
  • Works with Windows 7 through 11 plug-and-play on 8.1/10/11
  • Backward compatible with Bluetooth 5.0, 4.0, 3.0, 2.0

What It Is

The IHDAPP Bluetooth 5.1 USB Adapter adds Bluetooth 5.1 with EDR to a desktop or laptop through a standard USB port. It uses a Realtek RTL8761B chip and operates on the 2.402–2.480 GHz band with a 3 Mbps transfer rate and up to 20 m range in open space.

Who It Fits

It suits Windows 7 through 11 users who need to connect mice, keyboards, printers, speakers or up to 10 headphones at once. It is not for Mac OS users, and it will not help buyers who need a version newer than Bluetooth 5.1 or a non-USB interface.

Installation Notes

Windows 8, 10 and 11 work driver-free; Windows 7 and 8.1 require the driver from the included mini CD or the supplier download link. A common issue is plugging the adapter in before installing the driver on older Windows versions, which prevents the device from being recognised.

Questions about this item

Do I need a spare USB-A port on my computer for this Bluetooth 5.1 adapter?

Yes, the dongle plugs into any standard USB-A socket; Windows 8.1, 10 and 11 recognise it without extra drivers, while Windows 7 and 8 require the driver from the supplied mini CD or the Google Drive link.

Will my existing Bluetooth 5.0 mouse and keyboard stay connected when I add this adapter?

The adapter is backward compatible with Bluetooth 5.0, 4.0 and 3.0 devices, so current peripherals will pair normally and share the 10-device limit.

How can I verify the adapter is delivering the quoted 3 Mbps transfer rate after setup?

Open Windows Device Manager, confirm the Realtek RTL8761B chip appears under Bluetooth radios, then run a file transfer between paired devices and check the throughput reaches the 3 Mbps specification.
