Abstract: Disclosed are devices and methods for regulating providing a charge via a charge receiving port of one device, the one device coupled to another device having a charge providing port. In one embodiment, the ports can be coupled by a cable. In another embodiment, the ports can be coupled wirelessly. The charge delivering device may regulate a charge providing process, controlled by a charge regulating controller of the charge providing device and based, for example, upon predetermined criteria. A charge regulating controller can disable the charging process, monitor the charge depletion rate, or the charging process may be based upon user established criteria. A charge regulating controller of the other device can regulate the charge accepting process. Each device may take on both roles, that is providing charge and receiving charge.
