So far so good. I have used power adapter since my Apple Adapter got a short in the cord. I have owned various Apple Laptops and almost all of the power adapters have needed replacing. I like to buy Apple branded replacements but they cost twice as much as this one. I have been using it for several weeks without any problems.
Output:
Positive
