A Logitech K760. This is a solar powered wireless keyboard that connects via Bluetooth.

There is enough battery power in this keyboard to last up to 3 months in complete darkness.

Using Bluetooth you can use this keyboard on your iPhone, Smartphone, iPad, Tablet, PC and Macintosh.

This keyboard allows you to connect up to three different devices at once and gives you the ability to connect to each with a single key press.

I am currently selling this item as I have purchased the K750 solar powered keyboard which has more keys on the keyboard.
