My son and daughter have also each a Samsung cell phone (i9001). These phones work every cheap Noname charger. My Samsung Galaxy W (GT-i8150) but is very sensitive (whether 220V or 12V car) in terms of charging cable. Many charging cables are simply not recognized by my GT-i8150. This supplied car charger contrast works perfectly even in my GT-i8150. Additionally, it should also be mentioned that due to the asymmetric shape of the USB connector also blind (eg at night) you know how rum it has stuck in the phone.
