A:AnswerNo, it will not. This KB/Mouse will not support Bluetooth. Therefore will not work with Android phone via Bluetooth.
Logitech - K480 Bluetooth Multidevice Keyboard will work as a keyboard,
A:AnswerNo. But I would think you can use rechargeable batteries, you'd just have to remove the batteries to recharge them. Logitech claims the batteries in the keyboard should last 2 years.
A:AnswerKeyboard and mouse are pre-assigned to the USB Dongle and can only be install on one computer at a time. When done using in one PC, then you can remove the receiver and install it on another computer and continue using it.
