Rare specimen

After this charger I've been looking for. Although supply many car charger a high charge current, this will benefit but for most Smartphones little because they do not give as 'mains charger' to recognize. For then pulls the phone only max. 500mA, as it is mentioned on a USB port. As a result, the battery will discharge at a high load (for example, when used as a Navi) although the Phone on the charger plug depends.
Not so the anchor. This is recognized as an AC power supply and accordingly the phones operate with the maximum charging current. Now I can finally use my Galaxy S2 as Navi even over long distances.
Should also be noted that the device firmly mounted Micro USB charging cable is not too long. The cigarette lighter is located in the center console, a longer cable is probably required on most vehicles. However, this is thanks to the second USB connector no problem.
