Tiny, Reliable, and Plug-and-Play Bluetooth for Any PC
Tiny, Reliable, and Plug-and-Play Bluetooth for Any PC The TP-Link UB400 Bluetooth 4.0 adapter is a remarkably simple way to add Bluetooth to an older desktop or laptop that lacks it. It’s about the size of a fingernail—once plugged in, you can leave it there permanently without blocking adjacent USB ports. Setup is as easy as it gets: on Windows 10 or 11, it’s fully plug-and-play; for Windows 7 or XP, TP-Link provides free drivers. In my experience, installation took seconds and devices paired immediately. Performance is solid for its class. It maintains stable connections for headphones, mice, keyboards, and even game controllers within a reasonable 50- to 60-foot range. Audio quality over A2DP is clean, and latency with Bluetooth 4.0 peripherals is minimal for everyday use. It’s not built for high-end audio streaming or gaming headsets, but for standard wireless accessories it works seamlessly. I especially appreciate that it’s low-profile, energy-efficient, and doesn’t run hot even after hours of use. The connection is consistent, and it automatically reconnects to previously paired devices after reboot—no fiddling required. Bottom line: A dependable, compact, and truly plug-and-play Bluetooth dongle that delivers excellent value for basic wireless connectivity. Ideal for upgrading desktops or travel laptops, and proof that simple, inexpensive tech can still work perfectly.

Cheap bluetooth adapter
I bought this back in March of 2020 when I built my first computer and forgot to include a Bluetooth module. This device worked great and allowed me to use my wireless headphones with my computer. I have since then gotten a Bluetooth module but I still keep this adapter for whenever I need it and it hasn't failed me yet. It has a pretty small form factor which is nice because it doesn't stick out much and isn't an annoyance when using it. The range is okay (at least for the 2020 version), but once there are a couple walls between me and the adapter the Bluetooth starts to get pretty choppy. Overall, it is a sleek and durable adapter that I would recommend for anyone that needs Bluetooth

Smooth Connectivity with a Touch of Power
The TP-Link USB Bluetooth Adapter for PC is the kind of gadget that makes life just a little easier, a sleek intermediary between your devices and the digital world. Installing it is straightforward, and the Bluetooth 4.0 connection brings seamless communication to headphones, keyboards, mice, and other peripherals. There’s a certain satisfaction in watching technology work effortlessly, as if it anticipates your every need. While it performs admirably for most tasks, there are occasional hiccups in range and stability with more distant devices, which prevents it from feeling completely flawless. Nevertheless, its compact design, reliable pairing, and overall efficiency make it a dependable tool for everyday use. Four stars for a product that delivers connectivity with style and functionality, even if it occasionally demands a little patience.

Easy install, much cheaper than Bluetooth hardware replacement
I have a Lenovo Yoga laptop I bought in 2020 for college that has been nothing but a headache. Recently, the Bluetooth hardware completely failed and it would’ve required an extensive (and expensive) repair to get the hardware replaced. I use Bluetooth headphones to attend class lectures, and the laptop would’ve required another adapter to add an aux port to even try to use wired headphones. This little USB gadget fixed my problem for $10. Install was quick, easy, and done in about 5 minutes. I was concerned this would require some 3rd party Bluetooth menu to connect, but my laptop recognizes this adapter as a native Bluetooth drive, with all settings available via the same menu as before. The only small snag I had was that my Bluetooth devices wouldn’t connect until I removed and re-paired them in the settings menu, but they reconnected on the first try and now work flawlessly. You’ll need the model and version number to find the right driver to install. You can find the model number on your product packaging or this product listing under the “Product Specifications” section. The version number is printed on the bottom of the USB adapter itself.
