A power supply system includes an adapter adapted to covert AC power into DC power, a power supply chipset connected to the adapter, a main battery, a slave battery, and a control chipset connected to the power supply chipset, the main battery, and the slave battery. The power supply chipset is adapted to receive DC power provided by the adapter. The control chipset is configured to monitor whether the power supply chipset receives DC power. The power supply chipset can provide DC power to the electronic device system and charge the main battery and the slave battery when the power supply chipset receives DC power. The power supply chipset also can control the main battery and the slave battery providing power to the electronic device system when the power supply chipset does not receive DC power.
