If you have a car with cigarette lighter outlet(s), you should check out the Aukey CC-S1 car charger.
It turns your cigarette lighter outlet into a two port usb charging outlet. This style car charger is nothing new, however what makes this one appealing is that it sits flush to the edge of the outlet. Aesthetically it will look much cleaner compared to standard USB cigarette ports and it will also make it look like the outlet was always a USB charging port and not a re-purposed cigarette lighter port.
This charger has over 3700 positive reviews on Amazon with an average rating of 4.4 out of 5 stars. It’s worth considering if you have no use for that cigarette lighter.
