IK Multimedia shipped another clever gadget Thursday, the iRig PowerBridge. This device allows "continuous charging while also passing along audio and MIDI information between the digital iRig accessory and the iPhone, iPad or iPod touch." In other words, you can keep your iOS device charged while playing music with the company's iRig product line. The device has a low-noise power conditioner built into it, as well as several connection options. There are also versions for both Lightning and 30-Pin Dock iOS device models.
