A power adapter 100 includes a body 1 and a detachable plug unit 2. The body has a concave portion, formed for example on a corner portion, which includes a supporting wall 16, a blocking wall 19 perpendicularly connected to the supporting wall, a guiding means 161, and at least two contacts 3 projecting into the concave portion. The plug unit is slidably received within the concave portion of the body and has at least two blades 4 which may fold into a storage position. An elastic latch portion 19 retains the plug unit 2 on the body 1. The guiding means preferably consist of linearly extending ribs sliding within channels; the body may be provided with a central upstanding rectangular base 161 on which ribs (162, fig.3) extend forming grooves (163, fig.3); the underside of the plug unit may be recessed (23, fig.4) and formed with channels (234, fig.) and guide ribs (233, fig.4) which slide within the channels in the body unit. This enables the plug unit to be detached and interchanged with other plug units having different pin arrangements according to different countries.
