A power package includes a motor and at least one of a propeller or a propeller mounting structure. The propeller mounting structure is configured to detachably mount the propeller at the motor and includes a mounting seat configured to be fixed at an end surface of the motor and rotationally engage with the propeller, a lock member, and an elastic member configured to apply an elastic force to the lock member along an axial direction of a motor shaft of the motor to cause at least part of the lock member to block the propeller from being disengaged from the mounting seat. The motor shaft passes through the mounting seat. The propeller includes a connection assembly and a blade disposed at the connection assembly. The connection assembly is configured to mount at the motor shaft and includes an annular connector configured to rotationally engage with the propeller mounting structure.
