Review on Samsung Adaptive Charging Vehicle Charger by Zach Sornsin

Charges quickly, doesn't overheat your phone and even works with a wireless charging pad. Actually, I mainly use it with S7 tethered to a Samsung OEM wireless charger and it has no problem charging as long as the full Google map is shown when navigating with the phone. It will continue to charge while using the Google Nav app. In this case it's charging slowly, but it actually has a net positive power supply when the phone is displaying/refreshing/navigating.
