A power supply device includes an electrical connector and a power interrupt system. The electrical connector is configured to facilitate electrically coupling an electronic device to a power source to at least one of charge and power the electronic device. The power interrupt system selectively couples the power source to the electrical connector. The power interrupt system is configured to (a) provide energy to the electrical connector in response to at least one of (i) a first user request and (ii) a determination that the electronic device is coupled to the electrical connector, and (b) limit the energy provided to the electrical connector at least one of (i) in response to a second user request, (ii) in response to a determination that the electronic device is decoupled from the electrical connector, and (iii) after a threshold elapsed time.
