Tips:
1.Powered By USB Charging (No built-in battery )
We recommend that you use a 5V1A charger to power the adapter to avoid insufficient voltage and current, which may cause current sound or noise when the adapter is in use.
2.It’s a Bluetooth audio receiver only, not a transmitter. Can only be used for audio transmission,So you couldn’t use it for your keyboard, mouse, file transfer.
(The function of the Bluetooth receiver is to add Bluetooth wireless function to the wired speaker/headphone, so that the Bluetooth-enabled device such as the mobile phone can be wirelessly connected to the wired speaker/headphone through the adapter.)
