Aukey 2 Port Quick Charge 2.0 Car Charger
This has to be the best car charger i have ever used. It has 2 ports one is a 2.4a charge port while the other was a Qualcomm compatible charge port. My Galaxy S6 Edge charges even faster with this charger as it does with the charger that came with the phone. Head on over to the forums for more info and the link to purchase.
