The drive apparatus includes a housing, a DC brushless motor, a control unit, an adaptation unit, an alternating current (AC) input interface, a DC input interface, and a power storage. The housing includes a first portion and a second portion. A projection path defined by orthogonally projecting the first portion toward the second portion is defined as an installation range. The DC input interface is arranged in the installation range and is electrically connected to the control unit. The AC input interface is arranged in the installation range and is electrically connected to the adaptation unit. The power storage is detachably arranged at an installation position of the housing. When the power storage is arranged at the installation position, the power storage covers the AC input interface and is electrically connected to the DC input interface.
