Works like a "Super-Fast 2.0" charger should
It works great. I compared it to an original OEM version from Samsung. The case is definitely not the same. So, I must therefore assume that it is not an OEM model. But with that being said, it works fine. It is capable of doing the "Super Fast 2.0", charging. If you don't use a super-fast charging cable with it, it cannot charge the Super-Fast 2.0 speed. It can still charge; it just takes longer. How will it react to a bad battery, when trying to charge it? Does it have the safety issues built in to it? I do recommend it, however. I have been using them for a month and they are working seamlessly, so far. I took a star off, just because I'm guessing that it is not an OEM as described earlier.
