I have to change this connector I was trying to find out which Acer models have the same connector because they sell used ones at less than a third of the price of the new one. In a free market notice they show one identical to mine but they assign it to models 57333 - 5742 - 5336 and as the model I have is in the middle I guess it also works for me. So I have these two questions Question 1 How can I find out which Acer models have the same charging connector? Question 2 If the view in color and size is identical in that they sell to the one I have, can I assume that it will serve me even if it is from another Acer model?
