I have tried many others and they were all useless past a certain distance and caused my controllers to disconnect midway through games (always at the worst times as well). I installed this on a long extended active USB 3 cable and placed it slap bang between the two rooms and now everything connects instantly and doesn't drop out at the most annoying times!I Drivers installed instantly with Windows 11 so no faff required. Buy this if you want a good long range and stable bluetooth dongle. Review: Superb for my use case - For me, it started working as soon as I plugged it in; the driver installation was instant. Works as expected for my use case. I only use it for my wireless mouse, so cannot say about the range, latency, sound quality, bandwidth or speed. All I can say is that the connection never drops and there is no lag. ## Features - o-Sized – Ultra-small for convenient portability with reliable high performance - Supported Operating System – Windows 11/10/8.1/7 - Bluetooth 5.3 – Security and reliability improvement than last-gen Bluetooth - Bluetooth 5.0 - Backwards compatible with Bluetooth V4.0/3.0/2.1/2.0/1.1 devices, uses the latest Bluetooth 5.0 with low energy (BLE) technologyo-Sized – Ultra-small for convenient portability with reliable high performance, Dimensions: 0.58 × 0.27 × 0.74 in (14.8 × 6.8 × 18.9 mm)o size - Ultra small for convenient portability with reliable high performance, dimensions: 0.58 × 0.27 × 0.7 inches (14.8 × 6.8 × 18.9 mm) - Wireless Connectivity – Provides stable and convenient communication between Bluetooth devices and your PC or laptop ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09S15RLH5 | | Best Sellers Rank | 361 in Computers & Accessories ( See Top 100 in Computers & Accessories ) 3 in Bluetooth Network Adapters | | Box Contents | UB5A | | Brand | TP-Link | | Brand Name | TP-Link | | Color | Matte Black | | Colour | Matte Black | | Compatible Devices | Computer, Printer, Phone, Headset, Speaker, Keyboard, Laptop, Smartphone, Tablet | | Compatible Operating System Family | Windows | | Compatible devices | Computer, Printer, Phone, Headset, Speaker, Keyboard, Laptop, Smartphone, Tablet | | Country of Origin | China | | Customer Reviews | 4.5 out of 5 stars 62,539 Reviews | | Data Link Protocol | Bluetooth, USB | | Data link protocol | Bluetooth, USB | | Hardware Interface | Bluetooth, Bluetooth 5, USB | | Hardware interface | Bluetooth, Bluetooth 5 , USB | | Item Dimensions L x W x H | 15L x 7W x 19H millimetres | | Item Highlight | Plug & Play, Windows 11/10/8.1/7, Broader Coverage, BLE, Controller, Headset, Mouse, Keyboard | | Item Weight | 30 Grams | | Manufacturer | TP-Link | | Manufacturer Part Number | UB5A | | Minimum Required Operating System Version | Windows 7 | | Model Number | UB5A | | Number of Items | 1 | | Number of Packs | 1 | | Product dimensions | 15L x 7W x 19H millimetres | ## Product Details - **Brand:** TP-Link - **Colour:** Matte Black - **Compatible Operating System Family:** Windows - **Compatible devices:** Computer, Printer, Phone, Headset, Speaker, Keyboard, Laptop, Smartphone, Tablet - **Data link protocol:** Bluetooth, USB - **Hardware interface:** Bluetooth, Bluetooth 5, USB - **Item weight:** 30 Grams - **Minimum Required Operating System Version:** Windows 7 - **Number of Packs:** 1 - **Product dimensions:** 15L x 7W x 19H millimetres ## Images ![UB5A Bluetooth 5.4 USB Adapter for PC, Nano Bluetooth Dongle - Image 1](https://m.media-amazon.com/images/I/61zOA9oCfhL.jpg) ## Available Options This product comes in different **Set** options. ## Questions & Answers **Q: Does this work with a PS4 controller on pc?** A: Yes. You need to hold the share and ps button, once it starts blinking it's ready to pair with a PC **Q: I do not understand, does it act as a receiver or a transmitter when plugged into your PC or both ?, forgive my ignorance but this is all new to me.** A: It acts as transmitter, so that you can connect devices to your PC such as phones and other devices **Q: Will it work in a tv soundbar ?** A: It's likely this would work. I use my soundbar for listening to my phone AND my PC. If your phone can connect to your sound bar via Bluetooth, it's likely your PC would too :) **Q: My pc is connected to my phone but my phone isnt connected to my pc?** A: On Windows, the phone will not connect to the pc unless needed, it is only paired. For example, when you send a file you select the Bluetooth device then it will send it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It works! *by A***Y on 24 July 2026* I live in a flat and tend to move between different adjoining rooms to game, so wanted a good bluetooth dongle that could handle the long distance between the two rooms.

Works as expected for my use case. I only use it for my wireless mouse, so cannot say about the range, latency, sound quality, bandwidth or speed. All I can say is that the connection never drops and there is no lag. ### ⭐⭐⭐⭐ Good quality, not great range *by L***R on 21 April 2026* My desktop PC didn't have built-in Bluetooth so I grabbed this little dongle. You literally just plug it into a spare USB port and Windows recognises it straight away. It works perfectly for connecting my wireless earbuds with zero noticeable audio lag. The only reason for 4 stars is that the range drops off quite quickly if you walk into another room through a brick wall, but if you are sitting at the desk it is flawless. ## Frequently Bought Together - TP-Link UB5A Nano Bluetooth 5.3 USB Adapter for Multiple Devices, Long Range Bluetooth Adapter Compatible with Win 11/10/8.1/7, Dongle/Receiver, Plug & Play - TP-Link Archer T3U Plus WiFi Dongle, AC1300 High Gain Wireless WiFi Adapter, Dual Band USB 3.0 MU-MIMO WiFi Dongle with 5dBi Antenna for PC/Desktop/Laptop, Supports Windows 11/10/8.1/8/7XP, Mac OS - TP-Link Archer T2U Nano WiFi Dongle, AC600 Wireless USB wifi Adapter, Dual Band 5 GHz High Speed Wi-Fi dongle for PC, Desktop, Laptop, Supports Windows 11/10/8.1/8/7/XP, Mac OS X, Nano design --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/408658072-ub5a-bluetooth-5-4-usb-adapter-for-pc-nano-bluetooth](https://www.desertcart.jp/products/408658072-ub5a-bluetooth-5-4-usb-adapter-for-pc-nano-bluetooth) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-09-12*
