Good quality product that gives off a nice solid feel. Barely exceeds the cigarette lighter socket when inserted, but it is enough, in my case, to prevent the closure of the ashtray in which is taking (Seat Cordoba III). The green LED is too strong (use black tape or direct the charger once inserted a USB cable, the light is covered from the top and do not mind driving). Otherwise RAS, the charger delivers a fine power (2.1 Amp announced) and load without problems and an iPhone 3GS GPS Mappy.
