No idea lol. I guess ones that advertise 480 Mbps or faster should work for fast charging. These are the ones I bought: https://www.amazon.com/gp/aw/d/B015XPQ5KK/ref=mp_s_a_1_2?ie=UTF8&qid=1471985169&sr=8-2&pi=SY200_QL40&keywords=anker+usb&dpPl=1&dpID=417AS3T1OiL&ref=plSrch

Get a better car charger, I highly recommend Anker, they output enough amperage to charge a phone that unbranded chargers usually don't. Their micro USB cables are great too.
