Adaptador USB Bluetooth 5.0 ESPERANZA EA160 - Nano dongle, chipset Realtek, alcance 20 m, negro

The Esperanza EA160 stands out from typical Bluetooth dongles by combining Bluetooth 5.0 with a Realtek RTL8761B chipset in an ultra-compact nano form factor. It delivers a stable 20-meter wireless link for mice, keyboards, headphones, speakers and smartphones, with true plug-and-play on Windows 10 and 11. The low-profile design lets you leave it permanently in a USB port without blocking adjacent connectors, while the LED indicator confirms active pairing and data transfer at a glance.

Highlights

• Bluetooth 5.0 with backward compatibility to 4.0, 3.0, 2.1 and 2.0
• Realtek RTL8761B chipset for reliable connections and low latency
• Nano USB-A form factor – barely protrudes from the port
• Class 2 range up to 20 meters in open space
• Supports BLE (Bluetooth Low Energy) for energy-efficient peripherals
• Bus-powered – no external power supply needed
• Plug-and-play on Windows 10/11; driver required for Windows 7/8/8.1
• Broad profile support: A2DP, HSP, HFP, HID, AVRCP, PAN, GAVDP, DID, IOPT

In daily use

Plug the EA160 into any free USB-A port and it becomes a discreet wireless hub for your desktop or laptop. Pair a Bluetooth mouse and keyboard without occupying a USB receiver slot, stream music to wireless headphones or a speaker via A2DP, or sync data with a smartphone. The 20-meter range easily covers a large room or office, and the LED status light shows pairing and activity states. Because the adapter is powered directly from the USB bus, it draws minimal current and works immediately after boot. On Windows 10 and 11, the system recognises the dongle automatically; for older Windows versions, install the included driver from the manufacturer's website. The ABS and metal housing withstands everyday knocks, and the nano size means you can leave it in a laptop bag without worry.
