A power adapter having a replaceable and rotatable plug has a body having an annular chamber, two conducting elements inside the annular chamber, four channels recessed on a top thereof to communicate with the annular chamber, and an engagement slot abutting each of the four channels; and a hollow plug having two intermediate conducting elements, a cylinder protruding beyond a bottom of the plug and received in the annular chamber, four arced holes communicating with an inner portion of the plug, four engagement blocks protruding from a cylindrical periphery to respectively correspond to the four channels and four engagement slots, and at least two prongs mounted on a top thereof, one end of each of the two prongs penetrating through the plug to electrically connect with corresponding intermediate conducting elements. Given the aforementioned structure, the plug can be replaced and selectively oriented with respect to the body.
