I'm using this product in a Mazda MX5 and so far have encountered no issues with charging: you just plug it in and off she goes! As for the build quality, well, it feels very solid and looks great. The only reason I give it 4 stars instead of 5 is because the coiled cord really is quite short. It doesn't bother me much because the Mazda is a small car, but I imagine this may cause a problem if you are in a big vehicle and need the cord to stretch a considerable distance. But that really is a minor point, all in all, this is a lovely product!
