Works great!

I needed a new charging adapter for my work vehicle that could charge my phone in a hurry, and this does evactly that. It comes with 2 ports, one a rapid charging port that is a blue color and the other for normal charging. I only use the rapid charging port and so far it has performed perfectly. The adapter is small so it doesn't stick out very far and get in the way, holds the cable tightly in the port with no loose connection, and will charge my S7 from dead to fully charged in about an hour while the phone is in use.

If you are looking for a car adapter you can't go wrong with this one, I see it giving me a long time of great performance.
