In the description and picture, the female jack adapter allowed entry into diameter 2.5 mm and a diameter of 3.5 mm male outlet. Upon receipt of the package, my confusions was huge, I received a reverse adapter, AC-input diam.3,5 say a female and a male output mm mm diam.2,5
But given the product price, I have not returned. Too bad for me!
