This is a pretty sweet deal, especially when you consider that the Nokia Power Keyboard itself retails for $149 a pop. How do you make use of the Power Keyboard? For starters, it will be attached to the back of the Nokia Lumia 2520, where it works to offer a degree of protection to the device’s 10.1” display when closed. When you open up the Power Keyboard, it would then show off a physical keyboard, trackpad and a stand in order to prop the tablet up. Apart from that, this Power Keyboard will also be accompanied by two USB ports in addition to a battery pack which theoretically, will be able to give the Lumia 2520’s battery life a boost of up to 50%.
