Q: Unfortunately I shall not be able to review the Macally Power Adapter. I did not pay due attention to the fact that the AC adaptor works with G3 iBook and G4 PowerBook only.I plugged it in with a G4 iBook , it made some complaining noises and it died. Maybe it would be proper to really WARN that it will NOT work with a G4 iBook in CAPITAL LETTERS.$40.- down the drain!
A:
Negative
