Abstract: A mobile electronic device includes a main framework, back cover, expansion box, card reading module and battery module. The main framework has a motherboard. The back cover is disposed on the main framework and has an expansion window. The expansion box covers and closes the expansion window. The expansion box has therein an expansion chamber, a power chamber, and a communication opening whereby the expansion chamber and the power chamber communicate with each other. The expansion box has a wire connection opening in communication with the power chamber and with the expansion window. The card reading module and battery module are disposed in the expansion chamber and power chamber, respectively. The card reading module is connected to the motherboard by a signal wire via the communication opening and the wire connection opening. The battery module is connected to the motherboard by a power wire via the wire connection opening.

Abstract: An electronic device having a removable handle is provided and includes a handle, two connecting elements, and a body. The handle is coupled to the body through the connecting elements to allow a user to change the handle through the connecting elements as needed, thereby rendering the use of the handle highly flexible. Bumps of the connecting elements are disposed at concave portions on the body, respectively. The fastening components fasten the connecting elements to the body. Therefore, the connecting elements are firmly coupled to the body to enhance overall structural stability after assembly and usage safety of using the handle to carry the body.
