I have had to replace my powerbook power cord twice already. Both times before I broke the bank by purchasing the cord from apple. Big mistake. Although steep in price those things are C-H-E-A-P! This last time i decided to go with the Macally. What a great deal! Much more durable than then apple version. It is also more compact. The only thing missing is the indicator light to let you know if the battery is charging. Not a big deal for such a great price!
Output:
Positive
