INFORMATION PROCESSING APPARATUS HAVING AT LEAST ONE INTERFACE FOR ELECTRIC POWER TRANSFER, METHOD OF CONTROLLING INFORMATION PROCESSING APPARATUS TO TRANSFER ELECTRIC POWER TO AN EXTERNAL DEVICE, AND NON-TRANSITORY COMPUTER-READABLE RECORDING MEDIUM

A CPU of an MFP receives battery information from a first external device via a first interface, determines whether a total amount of electric power supplied to a plurality of interfaces from a power supply is maintained, and reduces an amount of the electric power supplied to the first external device via the first interface in a case where determining that the first external device has no battery based on the battery information in response to determining that the total amount of the electric power supplied to the plurality of the interfaces from the power supply is not maintained.
