It can't be slower since it's designed for the same voltage and all, it's a thinner cable sure but I've had mine for a while (like half a year or so) and it hasn't failed me yet at least.I was kinda thinking the thinner cable would make it charge slower, too.Dont buy retractable ones! The cable on those are so thin that after awhile it'll stop working from pulling apart so many times.
They're fairly cheap too so when mine start to act up I'll probably buy a new one.
I just like the compactness of it when traveling, I can fit it in my game case unlike the other USB cable I have.
