Input: This is not a fast charger, I bought one and compared it to the original which I also own and the voltage specs are different. That being said, it is a chinsee knockoff. There are also some design differences that give it away. I didn't use it so I can't comment on that aspect However if fast charhung is important to you do not buy this.
