The charger cable does what it should do, it loads my TomTom navigation device to the power outlet on. It invites also on quite quickly, in about an hour my Navi is fully charged. It is also convenient that you can make multiple plug connectors off. I use now though rather less, since I do not often find myself abroad, but it is still possible to charge his navigation in almost all countries, when his car is traveling times. I find it jdenfalls well that his Navi can be connected to the socket now, because I do not want to charge all devices on the PC. At the outlet there is simply faster than the PC. What I find is just a pity that there is no indicator light is attached, indicating the charge status of Navis. So you always have to turn to look at whether the Navi is fully charged, but that's not so tragic his Navi. So smite people.
