Power Covers, new battery-life-extending accessory for Microsoft's Surface tablets, will ship starting March 19 at a price of $199.99
Microsoft went live with details today on a web page that lets you pre-order the covers designed to extend the battery life of Microsoft's Surface Pro, Surface 2 and Surface Pro 2 tablets.
The Microsoft Store pre-order page claims the Power Covers -- Type covers with extra battery support -- will extend battery life by up to 70%.
The Power Covers weigh .55 pounds and are 9.75 mm thick. Unlike the new Surface Type 2 and Touch 2 covers though, they don't have back-lit keys.Source article
