This OEM has a much heavier duty cord and puts out 5.6volts at 800mh for a much faster charging rate than the original. As you may not know the Nokia 6015i phone was one of the first digital "not smart" phones with push button keys. I still have two for in-house calls only. No land line. Old but very reliable. I carry around a LG-GLANCE smart phone in a magnet snap-shut leather carry case.
