Charging device and charging system

摘要

A charging device includes a power adapter, a cable assembly, and a control module. The power adapter is used for converting a power supplied from an external power source to a form suitable for charging a battery of an electronic device. The power adapter includes a first magnetic element. The cable assembly is used for electrically connecting the power adapter with the electronic device such that the battery can be charged. The cable assembly includes a first plug connected to the power adapter and a second magnetic element disposed in the first plug. The control module is used for controlling the first magnetic element and the second magnetic element to engage with each other to disconnect the first plug from the power adapter when the battery has been fully recharged.
