Abstract: A separable mobile power source bracket is provided. The mobile power source is composed of a large edge external case, a small edge external case, a charging battery and a circuit module. Both the large edge external case and the small edge external case can be assembled into a completely external case through magnetic suction. The charging battery is accommodated inside the back surface case of the large edge external case. The external case can be provided for accommodating a mobile phone for protection. When the small edge external case is held and detached by imposing force, the small edge external case is peeled off the top surface of the large edge external case to lean the bottom surface of the small edge external case against the back surface of the large edge external case so that the mobile phone is at a tilt angle.
