A battery engagement structure used in a portable battery charging module is disclosed to include a housing accommodating an operation mechanism and a button such that when a battery pack inserted into the battery engagement opening at the housing, the locking bar of the operation mechanism is pushed away by the inserted battery pack. Pressing the button with the hand after charging, the locking bar is moved away from the battery engagement opening to unlock the battery pack. The moving direction of the locking bar is reversed to the pressing movement of the button by means of the action of the link of the operation mechanism, therefore the component parts of the battery charging module can be freely arranged to fully utilize the internal space of the module.
