This tiny USB 2.0 Bluetooth adapter enables wireless communication and data transfer, for example between two PCs or a PC and a mobile phone. Since the adapter protrudes only about 7 mm from the USB port, you can easily leave it connected to your notebook. Even when on the go in your bag, there is no risk of it breaking off. The adapter functions as a dual mode dongle and consumes little power thanks to the Bluetooth 4.0 standard.
