When you say “the car charger” are you referring to a USB car charger? I have a USB car charger made by Griffin and it works fine. Let’s you charge and listen at the same time. Not all USB chargers are the same. Some will not work with the Sansa Fuze (cannot say about their other models as I only have a Fuze). The Griffin USB wall charger works fine too.
You must use the Sansa USB cable, so keeping a spare in the car along with the car charger is a good idea.
