Adapter with a rechargeable power source for a consumer electronic device

An adapter for removably mounting an electronic device to an appliance host, the electronic device performing a data function and having a device mechanical coupling, and the appliance host having a power service and a host mechanical coupling that is incompatible with the device mechanical coupling and performing a useful cycle of operation on a consumer article, the adapter comprising:

• an adapter main body;
• a first mechanical coupling on the main body that is compatible with the device mechanical coupling for removably supporting the electronic device on the adapter, the adapter and the electronic device forming a functional unit when coupled together;
• a second mechanical coupling on the main body that is compatible with the host mechanical coupling for removably supporting the adapter on the appliance host;
• a first electrical interface on the main body for electrically coupling the adapter to the appliance host;
• and
• a rechargeable power source coupled with the first electrical interface for receiving the power service from the appliance host and using the power service to charge the power source when the adapter is coupled to the appliance host;
• wherein the electronic device receives the power service from the power source when the electronic device is coupled to the adapter to form the functional unit.
