Claim:
1. An apparatus, comprising: a battery interface; an interface to an electronic device; and a bidirectional voltage ratio converter configured to provide a bidirectional current flow between the battery interface and the electronic device, wherein the bidirectional voltage ratio converter comprises a pulse wide modulation oscillator, wherein the pulse wide modulation oscillator includes a divider and/or multiplexer and one or more switches comprising metal oxide semiconductor field effect transistors, and wherein the bidirectional voltage ratio converter is configured to provide the bidirectional current flow by at least: adapting a first energy received at the battery interface to an energy having at least a first energy characteristic adapted to the electronic device; and adapting a second energy received at the interface to an energy having at least a second energy characteristic adapted to a battery at the battery interface.
