A power-regulating charger is an apparatus used to manage the flow of electrical power to the battery of a mobile computing device. To accomplish this, the power-regulating charger includes an electrical plug, an output terminal, a shutoff switch, a microcontroller, and a wireless communication module. The electrical plug is a male connection terminal used to connect the power-regulating charger to an external power supply. The output terminal is an electrical terminal used to transfer power from the power-regulating charger into the connected mobile computing device. The shutoff switch is electrically connected between the electrical plug and the output terminal and is used to open the circuit between these two components. The microcontroller is a processing device that directs the shutoff switch to enable or inhibit the transfer of power. The wireless communication module receives commands that are wirelessly transmitted to the power-regulating charger from the mobile computing device.
