well, the wall socket has AC
The adaptor might convert to DC or affect the voltage.
Usually changing the voltage of AC is the function of a transformer.
So, I'd have to go with #1.
It will not generally affect the frequency of AC, and it certainly cannot convert from DC, since the wall outlet does not provide DC.
