I wonder if this one will be on sale due to Radio Shack going out of business.There is one I can highly recommend you. RadioShack makes it's in house brand Enercell. I bought a car charger from them Turkey Day Weekend 2013. I still have the charger to this day. It powered up a Lumia 810 I had at the time, and the 920 I have now, plus it charges my wife's 1520, which I notices some chargers don't work right. Most others would give the warning that the charger is not sending sufficient charge to it, but not the RadioShack one. It works very well...
