I want to put an iPhone dock in my car so I can use its apple iphone wireless remote. I was thinking of a USB car charger from the cigarette lighter, but I dont know if it has enough juice to power it just from the car input itself. or is it better off to get an apple iphone 3g car chargers instead? i have found some for a decent price around 10 bucks or so.. quality seems pretty goog so i have to make sure it would work the the new apple iphone 3g since i really love my iphone. Ideas anybody?
