The USB charging adapter supplied by Amazon faster than announced. After unpacking, I was initially attracted by the small size of the adapter. So the car so to try out. Then the disappointment: the adapter extends over 10 mm over the edge of the cigarette lighter "reason. I drive a BMW 1 Series (F20 / F21) with Non smoking package in this case is no cigarette lighter but outlets but a lot. (3 pcs.) have low installation depth. The advantage that the shaft of the adapter protrudes just 2 mm over the edge (and that was my decision to buy) is obsolete. In addition, that in the description of "blue" indicator light is "red" and quite obtrusively bright lights. However, the function is ok.
