I got a generic "made to OEM specifications" car charger in the past and within a week it broke, this one is doing very well after a month.This Samsung charger doesn't act like an AC charger but charges the phone, this is a bonus if you have the backlight on always when on AC. I can leave the phone uncovered while I drive.
