1, the difference in voltage: different charger output charging voltage of different charging speed and effect are naturally different, and the battery charging acceptance voltage has a certain standard specifications;
2, compatibility: the original charger is naturally more standard and more compatible than the ordinary, but theoretically speaking, as long as the output voltage of the charger is the same, it will not have much impact on the battery;
3, quality problems: the original charger will be better than the ordinary charger in terms of material material.
