Patent ID: 7989981

Claim:
A power adaptor and storage unit for providing input power to an electronic device, comprising: a. a housing, separate from the electronic device; b. a portable power module, detachably coupled to the housing; c. a first circuit disposed within the housing, the first circuit for optionally receiving a source power in a form unusable by the electronic device from an external source and converting the source power to the input power; d. a pass-through circuit disposed within the housing, the pass-through circuit for selectively providing the input power from the first circuit to the electronic device; e. a storage circuit disposed within the housing, the storage circuit for selectively storing the input power from the first circuit into the portable power module; and f. a discharge circuit disposed within the housing, the discharge circuit for selectively providing the input power to the electronic device from the portable power module; g. a control circuit coupled to the first circuit, the pass-through circuit, the storage circuit, the discharge circuit, and the portable power module, and the control circuit is configured to disable the pass-through circuit, disable the discharge circuit, and enable the storage circuit when the first circuit is coupled to the source power and the electronic device is not connected to the power adaptor and storage unit.
