The batteries in our mobile devices have not been able to keep up with the increased usage. As a result, we often find ourselves looking for places to charge. But many times, convenience and charging do not go hand in hand. At the Edison Junior Design Laboratory, we developed the perfect solution to this problem. POP, aka “Portable Power”, is a rechargeable portable battery with retractable cord reels for simultaneously charging multiple devices. Don’t be restricted by outlets or ugly chargers; with POP you are free to explore the vast world we live in, while remaining connected to it.
