I also agree with the previous review that it is better then the original charger because it is slimmer. Same run time though imo. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars A must have!!! *by L***A on Reviewed in the United States on December 11, 2018* Works great. Lighter than I was expecting. This oreo battery is better than the battery that came with my coat. I actually think it may last longer too.
