Systems and methods for managing power across electronic devices (210) and a charge reservoir (204) are discussed herein. A power management system (200) includes a charge reservoir (204) configured to store power, a first charger assembly (202), and a switch (212) coupled to the charge reservoir (204) and the first charger assembly (202). The charging monitor (206) may be coupled to the switch (212). The charging monitor(206) may be configured to query a charge state of a first electronic device (210), receive the charge state of the first electronic device from the first electronic device (210), compare the charge state of the first electronic device to a threshold value, and activate the switch (212) when the charge state is less than the threshold value. The activation may cause power to be transferred from the charge reservoir (204) to the first electronic device (210) via the first charger assembly (202).
