You’re looking at a 15,000 mAh battery pack, called the Limefuel Lite USB Battery Pack. That’s a lot of mAh’s, which means you can charge phones several times. Better yet, it comes with two USB ports, so you and a friend can both get juiced up at the same time. No more arguing over who gets to use the external battery! A digital display tells you just how much power is left, and it even has a built-in flashlight, though we’re not sure why. It might as well have had a lighter… Anyway, it’s normally $55, and today it’s $34.99.
