One of the top makers of PC accessories blesses us with the most power efficient wireless keyboard and mouse ever created. Logitech's keyboard absorbs energy from both indoor and outdoor environments to achieve long-lasting power. Plus, there's an app that informs users of energy levels and how much juice is being generated from a certain source. What about the Marathon Mouse? It's capable of running up to three years on a single set of batteries. Booyah!
