A wireless power adapter that mounts to the docking station port of a portable computer, such as a laptop computer, notebook computer or tablet computer. The wireless power adapter includes a docking port electrical connector selected to interface with the pre-existing docking port electrical connector on the portable computer. The adapter docking port electrical connector includes power pins to connect with the pre-existing power pins of the portable computer docking port electrical connector. The wireless power adapter may include an inductive secondary to wirelessly receive power from an inductive primary. The wireless power adapter may include a mechanical connector that interfaces with the pre-existing docking station mechanical connector on the portable computer. The present invention may also include a remote inductive power supply having a base adapted to support the laptop and adapter combination. The base may includes inductive power supply circuitry and an inductive primary to produce an inductive field to wirelessly provide power to the adapter and ultimately the portable computer. The remote inductive power supply may alternatively be embedded within a work surface, such as a desktop.
