There are car charges with the same Qualcomm "Quick Charge 2" technology as the Turbo charger that comes with the phone. Not sure if the Verizon one mentioned in this thread is one of them or not. I got one by GetWow for Christmas, but haven't had the chance to evaluate it yet. I don't think I'll need a car charger very often, but it would be nice to have one that's fast if you need it. Just search for Quick Charge 2.0 car charger.
...To follow up, I used the GetWow car charger this morning on the way to work. My phone went from 57% to 86% charge in 30 minutes. I think that's about what the turbo charger that came with the phone would do. Curiously, the phone did not report "turbo charger connected". Maybe that's because the voltage is only 12V from the car, not sure.
