The Neosocket works by storing the excess energy produced by your alternator and releasing it when there's a sudden drain. You can say that the battery already does this, but it supplies a CONSTANT supply of energy. What the Neosocket does is give out little bursts when needed, preventing the alternator from gearing up to meet the electrical needs of your vehicle. Since the alternator isn't geared up as often, that's less power that the engine needs to produce to run it, saving you gas.
