1. An apparatus, comprising:
- a single bidirectional voltage converter circuit arranged to operate in a charging mode or a delivery mode; and
a control module to selectively operate the single bidirectional voltage converter circuit in the charging mode or the delivery mode based on information received from an interface, the information comprising characteristics of a device attached to the interface, the interface comprising at least one data connection arranged to allow for an exchange information between the apparatus and the device attached to the interface and at least one power connection arranged to allow for a flow of power between the apparatus and the device attached to the interface, the charging mode to convert a voltage provided by the interface into a charging voltage employed by an energy storage module, and the delivery mode to convert a voltage provided by the energy storage module into a voltage employed by the interface.

Abstract
Power management techniques are disclosed. For instance, an apparatus may include a bidirectional voltage converter circuit, and a control module that selectively operates the bidirectional voltage converter circuit in a charging mode and a delivery mode. The charging mode converts a voltage provided by an interface (e.g., a USB interface) into a charging voltage employed by an energy storage module (e.g., a rechargeable battery). Conversely, the delivery mode converts a voltage provided by the energy storage module into a voltage employed by the interface.
