Has anyone used the NewerTech iBook chargers before? I was wondering how reliable they were compared to the OEM chargers from Apple. I have bought a couple off of amazon, third party chargers, but those seem to last a couple months, tops. I was just wondering if the NewerTech Charger is the best option for my iBook G4[1.42Ghz model.] I can't resolder my other 2 apple chargers and I can't find new OEM chargers locally so I need to buy another one. Thanks!
