Baseus Encok BA04+ Bluetooth 5.4 USB adapter, black

The Baseus Encok BA04+ USB adapter is a compact Bluetooth dongle that provides a fast and stable wireless connection for computers, laptops and other USB-A devices. Equipped with Bluetooth 5.4, it delivers low latency, efficient power usage and a connection range up to 20 meters in unobstructed conditions. The adapter supports both audio transmission and data exchange, making it suitable for work tasks and multimedia or gaming applications.

Advantages

The built-in Bluetooth 5.4 chipset ensures bidirectional data transmission with reduced interference and low power consumption, while an AI-assisted digital algorithm amplifies the antenna signal to keep the connection stable across rooms.
