Apple’s laptop charger, the MagSafe, is wonderful. Few other hardware makers have such an elegant way to charge their devices. Apple’s Lightning cable is pretty well-designed too, but what if iPhones could also use a magnetic charger? That’s what a new battery case Kickstarter called Cabin is promising. Cabin is primarily a new battery case: its main product adds an 2200mAh external battery to your device, as other battery cases available on the market do. But it also comes with two very interesting accessories. First, there’s something called MicroAdapter, a little plug-in for the iPhone’s lightning port that turns it into a magnetic socket. That pairs very well with MagAdapter, which plugs into the end of a Lightning cable. Plug a MagAdapter-equipped Lightning cable into an iPhone with a MicroAdapter, and you’ve got yourself a bootleg MagSafe-style setup.
