In the theme of cheap chargers http://dx.com/p/car-cigarette-powere...d-black-222339

Don't know about the quality yet though, just ordered it just because I wanted to change my single adapter to dual one, and it looked nice enough for testing.

EDIT:
Finally arrived and tested that piece of crap shitty piece of charger. I want to say what Linus would say. But that one is utter crap and can charge max 100mA at most if anything. So not recomending it.
