Power supply apparatus
First Claim
1. A power supply apparatus which supplies power to an external apparatus by using a battery pack, the power supply apparatus comprising:
- a connector to which the battery pack is connected, the battery pack being electrically connectable to another apparatus and being detached from the other apparatus when connected to the connector;
a power receiver configured to receive power supplied from an external power source of a type different from a type of the battery pack;
an outlet configured to supply power to the external apparatus via a power receiver of the external apparatus through connection of the power receiver of the external apparatus to the outlet; and
a switching circuit configured to switch between (i) outputting, to the outlet, first power which is the power output from a terminal of the battery pack via the connector and (ii) outputting, to the outlet, second power which is the power supplied from the external power source via the power receiver of the power supply apparatus.

Abstract
A power supply apparatus includes: a connection unit to which a battery pack is connected; a power conversion unit which converts direct current power output from the battery pack via the connection unit into a first power; a power plug which is connected to an external power source; a power supplying unit to which a power receiving unit of the external apparatus is connected to supply the first power output from the power conversion unit or a second power which is the power supplied from the external power source via the power plug; and a switching unit which switches between outputting the first power to the power supplying unit and outputting the second power to the power supplying unit.

5. A power supply apparatus which supplies power to an external apparatus by using a battery pack, the power supply apparatus comprising:
-
a connector to which the battery pack is connected, the battery pack being electrically connectable to another apparatus and being detached from the other apparatus when connected to the connector; a power receiver configured to receive power supplied from an external power source of a type different from a type of the battery pack; a first power supply configured to supply power to the external apparatus via a power receiver of the external apparatus through connection of the power receiver of the external apparatus to the first power supply; a switching circuit configured to switch between (i) outputting, to the first power supply, first power which is the power output from a terminal of the battery pack via the connector and (ii) outputting, to the first power supply, second power which is the power supplied from the external power source via the power receiver of the power supply apparatus; and an input receiver configured to receive an input from a user, wherein when the input received by the input receiver indicates a mode 1 and the terminal of the battery pack is connected to the connector, the switching circuit is configured to output the first power to the first power supply regardless of whether or not power is supplied from the external power source to the power supply apparatus. - View Dependent Claims (6, 7, 8, 9)

12. A power supply apparatus which supplies power to an external apparatus by using a battery pack, the power supply apparatus comprising:
-
a connector to which the battery pack is connected, the battery pack being electrically connectable to another apparatus and being detached from the other apparatus when connected to the connector; a power receiver configured to receive power supplied from an external power source of a type different from a type of the battery pack; a first power supply configured to supply power to the external apparatus via a power receiver of the external apparatus through connection of the power receiver of the external apparatus to the first power supply; a switching circuit configured to switch between (i) outputting, to the first power supply, first power which is the power output from a terminal of the battery pack via the connector and (ii) outputting, to the first power supply, second power which is the power supplied from the external power source via the power receiver of the power supply apparatus; a plurality of the connectors to each of which the terminal of the battery pack is connected; a detector configured to detect charge amounts of a plurality of the battery packs each of which is connected to the detector via a different one of the connectors; and a charge controller configured to perform charging control by using power of at least one of the battery packs that contains a charge amount more than an average amount of the charge amounts detected by the detector to charge a different at least one of the battery packs. - View Dependent Claims (13, 14)
