We know that the Angry Birds franchise from Rovio is insanely popular, after all how many games out there can inspire t-shirts, mugs, caps, plushies and even a theme park of its own. Not many would be the answer. Well, looking to add to that list of Angry Birds merchandize (we're not even sure if these are official/licensed) would be these Angry Birds Portable Power Stations, which as the name implies are portable back-up battery chargers for your smartphone. In this case, it seems that these portable power stations are being aimed at Apple's iPhone and feature a battery storage capacity of 1,900mAh.
