New input: I bought this charger thinking that it would be compatible with my late 2005 iBook G4. The description page has nothing stating that it is not for ibook G4 but only for Powerbook G4 and ibook G3. Also, after only about 3 weeks of use the charger died completely. This is by far the worst charger I have ever had. Pros: quick ship Cons: incorrect description, lack of durability
Solution:
Negative
