I prefer to avoid using my phone’s USB port by charging my phone wirelessly. I had seen accelerated wear, even failure, of the USB port on previous phones. So I knew I wanted to use wireless charging in the car to reduce wear and tear. I found a Qi charger I liked and then GOOP’d it to a ProClip mount that’s designed for the Mk7. I’d share more about my Qi charger, but it’s no longer available. I don’t like unsightly power cord runs, so I routed my cord through the AC duct and behind the dash, plugging it into the 12V outlet that’s inside my arm rest. I had to disassemble the center console to pull it off, but I’m pleased with the outcome. It’s only drawback is that it doesn’t deliver enough current to keep up with charging demands when the phone is using high-current apps such as GPS, mapping, or navigation. Still, the rate of discharge is reduced and battery life is prolonged beyond having no charger at all. I’ve shared photos in an album below.
Update: I decided to move away from this mount and in favor of the D-Dock in September 2018. I love it; plus, it delivers enough current to charge the phone while it’s in use. See this entry for details.
