Patent ID: 8308496

Claim:
An electrical charger comprising: a base unit configured for being coupled to an electronic device; and an adaptor unit configured for being coupled to a power supply; wherein the base unit includes an electrical connector plug; and wherein the adaptor unit includes an electrical connector plug receiving receptacle configured for receiving the electrical connector plug; and wherein, after the electrical connector plug is removably received within the electrical connector plug receiving receptacle and while the electrical connector plug is disposed within the electrical connector plug receiving receptacle, upon rotation of the base unit relative to the adaptor unit, the electrical connector plug becomes disposed in an electrically coupled state with the adaptor unit such that, when the adaptor unit becomes disposed in electrical communication with a power supply and the base unit becomes disposed in an electrical coupling relationship with an electronic device and the electrical connector plug becomes disposed in the electrically coupled state with the adaptor unit, power is supplied to the electronic device; and wherein the external surfaces of the base unit and the adaptor unit include at least partially matching contours that provide a visual indication whether the electrical connector plug is disposed, relative to the adaptor unit, in the electrically coupled state or in an electrically uncoupled state.
