I specifically chose this model because I read the back of a customer indicating that worked perfectly in a alfa romeo 147. Having this car, it has guided my choice. For every cigarette lighter adapter / usb does not work in any car. I bought AppStore and the first model was not working (the contacts were not because the adapter was too short), I exchanged against another, longer but moving in the cigarette lighter, so that contact is broken if we move the adapter, for example by simply taking the phone, which moves the usb cable, which moves the adapter. This dual model piccolino home hama is, meanwhile, in a perfect alfa romeo 147. The contact is made and the adapter does not move. I did not test the load capacity of two devices at once including the ability to charge two devices by turning energy-intensive applications, but I'm already satisfied with this product that allows me to use my smartphone with a GPS app. I was delivered very quickly, since the delivery date was announced tomorrow.
