mophie was one of the huge buzz companies of CES 2014 in Las Vegas.  This was partly due to their brand new release of the mophie space pack which is the world’s first rechargeable battery case with local built-in storage made for iPhone 5s/5.  To celebrate CES, mophie in collaboration with Mirrored Media, the Cosmopolitan and C3, threw a concert event at the Cosmopolitans's new theater, The Chelsea.  The concert featured performances from GROUPLOVE and Cage the Elephant.

On December 29th, 2013, The Cosmopolitan unveils The Chelsea, its newest event and performance space. An abandoned glass factory turned working theater was the inspiration for this venue with a stunning combination of industrial grit and artistic glamour. This 40,000 square-foot venue split over two levels offers guests a more avant-garde approach to entertainment with cast glass chandeliers, a vintage lobby bar, private VIP opera boxes and a decorative grand staircase.
