Dark Energy Reservoir
Make dead devices a thing of the past with the Dark Energy Reservoir ($129). You've all been in situations where your smartphone, tablet, or camera needed some extra juice — whether you're traveling on a plane, train, or bus, you're in an emergency scenario, or you're outdoors miles from an outlet. This slim, portable charger holds enough power to charge the average smartphone for an entire week, and it does it as fast as a wall outlet. With the ability to charge two devices at once, and compatibility with any USB charging device, you'll never have to worry about charging again.
