The adaptor that comes with the Apple Powerbook did not last as long as it should have! Then to charge that expensive cost for replacement...Shame on them! I accidentally dropped and bent the first adaptor that I bought from you and replaced it and still have enough left over to buy another if needed!!! WHY? Apple?
Output:
Positive
