This TP-Link UB4A nano USB Bluetooth adapter is a tiny but powerful solution for adding Bluetooth 4.0 connectivity to your PC. With low-energy BLE support, it is ideal for connecting wireless controllers, headsets, mice, and keyboards without draining your laptop's battery. Measuring just a few millimetres, it stays almost hidden in your USB port, making it perfect for portable use.

Installation is effortless on Windows 8, 8.1, and 10 – just plug it in and it works straight away. It also supports Windows 7 and XP after a quick driver download. While it lacks Bluetooth 5.0 speeds, the 4.0 standard still offers reliable, stable connections for everyday peripherals.

Currently priced at just £3.69, down from the usual £9.99, this is a massive 63% discount that looks like a pricing mistake. With over 10,000 positive reviews and a 4.4-star rating, it is a proven, budget-friendly option for anyone who needs Bluetooth on their desktop or older laptop. At this price, it is a no-brainer for gamers, office workers, or anyone tired of USB cables.

The adapter is backward compatible with older Bluetooth versions, so it works with a wide range of devices. Its nano size means you can leave it plugged in while traveling without worrying about breaking it off. Just be aware that it does not support Apple's macOS or Linux out of the box.

This TP-Link UB4A Bluetooth adapter is normally priced at £9.99, but Amazon UK currently lists it at just £3.69 – a 63% saving of £6.30. This sharp drop suggests a pricing mistake, as the discount is far deeper than typical deals. Given high demand and limited stock at this price, it may not last long. If you need a cheap Bluetooth dongle, this is an exceptional opportunity.
