Direct current voltage adapter i.e. direct current box, has generator obtaining efficiency, where adapter adapts voltages or power from one side to another side, and voltages or power ratio in series circuit or parallel circuit are balanced

摘要

The adapter (13) has a generator obtaining a best possible efficiency by its application, where the adapter adapts voltages or power from one side to another side. Different voltages or power ratio in a series circuit or parallel circuit are balanced, and power differences are balanced.
