While it is recommended as a very good charger, Kemali has a stamp with the name of Qualcomm on the product, I can say with certainty that the box charges normally but in no way quickly. I tried it on many devices to see if any of them would show me the quick charging indication, but in vain... otherwise I have no complaints and I use it daily but with the condition and certainty that it is not a fast charger as it claims
