I'm getting a really cool Airdock charger that I'm going to mount in my car. Now I want to find the right hard wired 12v to 5v converter. I need 2 amps of current and the connector is Micro USB but I can splice in to that. It seems like a simple thing but looking on the internet, reviews are mixed on all the Chinese stuff, nothing is name brand and most don't list their current. What I want is something that will last for a couple years at least and if/when it fails, it shouldn't burn down my car. Let me know what works or better yet, what doesn't work.
