Nokia's Windows RT tablet cover to include the battery pack?14
The exciting thing about Nokia's cover is that it will be embedded with a battery pack. This will not only allow the tablet's internal battery to recharge, but will also provide extra power for users of the slate on the go. The cover, which apparently covers the tablet "like a book," will click into place. The internal battery on the model is supposed to offer 10 hours of use and has fast recharging capabilities that quickly recharge the cell to 50%.
Those with knowledge of Nokia's plans say that the Finnish based firm will build a limited number of Windows RT tablets with the goal in mind to eventually offer the device with Windows 8. And these sources confirm Nokia's intention to show off the tablet in Barcelona at MWC 2013 in February.
