The power supply includes a battery, a first connector for detachably connecting the AC adaptor, a switch for switching a mode for performing a power supply to the electronic apparatus by an output of the battery or a mode for performing such a power supply by an output of the AC adaptor connected to the first connector, and a second connector for a power source output which is detachably connected to an AC adaptor connector of the electronic apparatus. When the AC adaptor is not connected to the first connector, the output of the battery is applied to the second connector through the switch.
