Plug-in

Plug-in
 

What's the right way for saying plug in, as in the place on the wall where you plug in a power cord. Is encufe right?

enchufe y tomacorrientes

and i think there is another more idiomatic term which i can't recall.

celador it's right.
in Spain it's enchufe or toma de corriente

enchufe
 

To plug in is enchufe. To plug in - enchufar, exam. plug it in - enchufala

In Mexico, in addition to enchufe and toma de corriente, you can also use contacto or contacto de luz.

This is the same word, but another meaning, how to say plugin but as a toolbar or a plugin for a program?

That was it ! contacto del luz. I knew i'd seen something like that.

and the electricity, or power is just called simply.. el hyrdo o hidroelélectrico

plugin for a program?
Usually...... Plug-in :D
