I had a Tylt car mount, which was great at charging my old phone. However, the new large screen phones with QHD resolution just draw more battery than the Tylt produces, creating a slow loss of battery over time.
I got this mount and was very impressed that it comes with a windshield mount AND an AC vent mount! That's great, because my phone was always prone to overheating in the sun on long trips. Now it stays cool, with cold air blowing on it, and the mount actually keeps my phone charged!
