Why Las Vegas? Because just like the American city of lights and action, our beloved iPhones demand power to keep us in action! The latest urban essential from the prolific founders of Danish-brand Urbanista, Johan Wahlbäck and Daniel Roos, the "Las Vegas" power case doubles the life of the iPhone 4 and 4S in a super-slim, super light-weight frame (only 70 grams!). There are countless charging iPhone cases out there, but none as cool or effective as this one. The sensible construction features the battery on the backside: simply slide the iPhone into it. Click the frame bumpers (a.k.a. side panels) into place. Each packet comes with a choice of red, black or silver bumpers. The bumper is slightly raised, protecting the screen. We say Viva Las Vegas!
