We purchased this because my wife's TomTom did not come with a home charger. I think we have only used it once. TomTom GPS devices come with a car charger and, being a GPS, that is where you use them. I find no need to have a home charger since you can just plug it into your car. If I had the chance, I would go back and have not purchased this item. Don't get me wrong, there is nothing wrong with it, it works great. There is just no need for it.
