Smart Charging Cable and Method for Operating a Portable Electronic Device

摘要

A smart charging cable and a method of operating the cable are disclosed. The cable can analyze any input voltage to determine whether the input voltage is sufficient to charge the battery of an electronic device and/or to operate the electronic device. If not, the cable is capable of transforming the input voltage to a voltage sufficient to charge and/or operate.

主权项

1. A method for providing power to an electronic device, comprising the steps of:
(a) electrically connecting a cable to the electronic device and to an electrical power source so that the electrical power source charges a battery associated with the electronic device or provides power to the electronic device via the cable; (b) analyzing a first voltage of the power source with an analyzing circuitry located on the cable; and (c) dependent on a result from step (b) transforming the first voltage to a second voltage sufficient to charge the battery or to operate the electronic device.
