Question

my printer's power cord, my laptop's power cord, my ps2's power cord and even my psp's power cord are two piece cords.its usually a short cord that plugs into a wall then plugs into a box that has another cord that plugs into the device.do they do that so that u can lose the small end of the cord and have to but a whole new power cord set?

Answer 1

They do that so they don't need to change the whole thing to convert to another voltage and plug configuration for another country..

Answer 2

Because of the different outlets in different countries.  By have a small piece that goes from the wall to the power supply they minimize the cost of having different cords for each country.  You should be able to replace just that piece.
