When indie British designer Richard Nicoll and British telecommunications giant Vodafone teamed up, from it sprung a sleek bag built to charge your cell phone on the go. While it looks strikingly close to the iconic Herm?s Birkin, its insides are all different. It’s battery powered to give your smartphone or tablet battery for days, and it’s got a Bluetooth enabled LED charm that blinks and twinks when with incoming calls and battery life alerts. In short, it’s a serious lifesaver. Says Nicoll of the project in the press release, “We wanted to create a collaborative product that fused fashion and technology. Vodafone helped bring this idea alive in a way that we never could have done ourselves.” It’ll be out in Fall of 2012, so until then, you’re tied to the wall.
