Abstract: An intelligent identification charging method includes the steps of: monitoring the voltage signal at the detection pin of the connector; generating a first voltage control signal according to the voltage signal at the detection pin; regulating the output voltage according to the first voltage control signal; and outputting the output voltage via the first charging pin of connector. A corresponding voltage is output by gathering a signal at the detection pin of the connector, and controlling the voltage according to the gathered signal at the detection pin so as to charge for the different electronic devices, which solves the problem that power adapters of all kinds of electronic products are not matched with each other. The intelligent identification charging device can be compatible with the connection of a USB interface, so that it can charge for the electronic device by the USB connector.

Abstract: This invention relates to a connector adaptor of an electronic device. In one embodiment, the connector adaptor comprises an outer frame for receiving and protecting the electronic device, wherein one side wall of the outer frame is internally provided with a plug which is in butt connection with a charging connector circuit of the electronic device; and one side wall of the outer frame is externally provided with a first USB interface for connecting with an external device through a data line to realize charging the electronic device.
