Abstract
A power supply unit (PSU) configured to provide electrical power to an electronic device. The PSU may include a PSU control circuit configured to, via a power meter, detect that electrical power conveyed to the electronic device is above a timer starting threshold. In a first charging mode with a first predetermined charging duration, the PSU control circuit may control the PSU to convey electrical power to the electronic device with a first power ceiling. Subsequently to the first predetermined charging duration elapsing, in a second charging mode with a second predetermined charging duration, the PSU control circuit may control the PSU to convey electrical power to the electronic device with a second power ceiling that is lower than the first power ceiling. Subsequently to the second predetermined charging duration elapsing, the PSU control circuit may control the PSU to return to the first charging mode.
