Transfer of Battery Charge from Donor to Recipient Appliance

Abstract:

Appliances, such as earbuds, configured to be used in pairs or otherwise configured to be operated in communication with one another, are arranged for transferring charge from a donor appliance to a recipient appliance. For the earbud system, a first earbud includes an external contact operatively coupled to the first battery, and the second earbud includes a complementary external contact operatively coupled to the second battery. The external contact on the first earbud and the complementary external contact on the second earbud are arranged for electrical connection to provide power from the first battery on the first earbud for charging the second battery on the second earbud, so that the second earbud can act as a recipient of power from the first earbud which acts as a donor of power.
