Wireless power receiving apparatus 150 is retrofitted to a portable electrical device 100 to enable the device to receive power wirelessly. The apparatus comprises a power-receiving element 200 adapted to be attached to the device, e.g. by adhesive 201, and also being adapted to receive power wirelessly from a transmitter of power when the element and transmitter are in proximity with one another. One or more power connectors 203 are connected electrically to the power-receiving element and are adapted to be connected, when the apparatus is in use, to one or more corresponding power connectors 101 of the portable electrical device to deliver power received by the element to the device. The power-receiving element may be in the form of a sticker or may be carried by or incorporated in a replacement cover portion for the portable electrical device.

1. Inductive power-receiving adapter for use with a portable electrical device to enable the device to receive power wirelessly by electromagnetic induction, the adapter comprising: an inductive power-receiving element adapted to receive power wirelessly by electromagnetic induction from a transmitter of power when the element and transmitter are in proximity with one another;a first adapter connector for electrically connecting the inductive power-receiving adapter to a portable electrical device to deliver power received by the inductive power-receiving element to the portable electrical device;a second adapter connector for electrically connecting equipment to the inductive power-receiving adapter; anda pass-through connection in the inductive power-receiving adapter for electrically connecting the first adapter connector and the second adapter connector wherein the pass-through connection enables: power delivery from the equipment to the portable electrical device through the inductive power-receiving adapter andcommunication between the equipment and the portable electrical device through the adapter. 2. Adapter as claimed in claim 1, wherein said power-receiving element is adapted to be attached adhesively to the device when the adapter is in use. 3. Adapter as claimed in claim 1, further comprising mechanical attachment means adapted to attach the power-receiving element mechanically to the device when the adapter is in use. 4. Adapter as claimed in claim 1, wherein said power-receiving element forms part of a replacement cover portion of the portable electrical device. 5. Adapter as claimed in claim 1, wherein said power-receiving element and the first adapter connector are connected rigidly together, whereby connection of said first adapter connector to the portable electrical device serves to attach the power-receiving element mechanically to the device. 6. Adapter as claimed in claim 1, wherein said first adapter connector comprises a flexible connecting member for connecting said first adapter connector flexibly to said inductive power-receiving element. 7. Adapter as claimed in claim 6, wherein said flexible connecting member also serves to connect said first adapter connector electrically to the power-receiving element. 8. Adapter as claimed in claim 1, having one or more electrical connections extending between said power-receiving element and said first adapter connector, said one or more electrical connections being detachable from said power-receiving element and/or from said first adapter connector when the adapter is not in use. 9. Adapter as claimed in claim 1, wherein said first adapter connector and said second adapter connector each provide a connector for purposes other than power delivery, and said pass-through connection arrangement serves to connect corresponding connectors of said first adapter connector and said second adapter connector for said other purposes. 10. Adapter as claimed in claim 1, further comprising: power-conditioning circuitry operable to condition the power received by the power-receiving element prior to delivery to the portable electrical device. 11. Adapter as claimed in claim 1, wherein said power-receiving element is small relative to said portable electrical device. 12. Adapter as claimed in claim 1, wherein said power-receiving element is thin relative to said portable electrical device. 13. Adapter as claimed in claim 1, wherein a volume occupied by said power-receiving element is small in comparison with a volume occupied by said portable electrical device. 14. Adapter as claimed in claim 1, wherein said power-receiving element is of sufficiently small dimensions that, when attached to the portable electrical device, it does not substantially alter the ergonomics of the device. 15. Adapter as claimed in claim 1, wherein parts of said power-receiving element that are visible to a user of the device when the element is attached to the device have an external appearance which conforms to an external appearance of adjacent parts of the device. 16. Adapter as claimed in claim 1, wherein a part of said power-receiving element which must be placed in proximity with the transmitter is marked or colored or labeled distinctively. 17. Adapter as claimed in claim 1, wherein said power-receiving element has, at a surface thereof that is visible to a user of the portable electrical device when the element is attached to the device, a substantially transparent pocket for carrying an insert to be visible to the user. 18. Adapter as claimed in claim 1, further comprising an indicator which produces a predetermined indication of an operating state of the adapter. 19. Adapter as claimed in claim 1, wherein said power-receiving element is substantially flat. 20. Adapter as claimed in claim 1, wherein said power-receiving element is flexible. 21. In combination a portable electrical device and inductive power receiving adapter as claimed in claim 1. 22. The combination of claim 21, wherein said power-receiving element is attached to an external surface portion of the device. 23. A method of adapting a portable electrical device having no inductive power receiving capability to have such a capability by installing an inductive power-receiving adapter, the method comprising: providing the inductive power-receiving adapter having an inductive power-receiving element, a first adapter connector for electrically connecting the adapter to the portable electrical device, a second adapter connector for electrically connecting the adapter to equipment, and a pass-through connection electrically connecting the first adapter connector and the second adapter connector;attaching the inductive power-receiving element to the portable electrical device, the element being adapted to receive power wirelessly by electromagnetic induction from a transmitter of power when the element and transmitter are in proximity with one another; andconnecting the first adapter connector to a power connector of the device so that power received by the element can be delivered to the device;connecting the second adapter connector to an equipment connector of equipment; andproviding: power delivery from the equipment through the adapter to the portable electrical device, andcommunication between the equipment and the portable electrical device through the adapter.
