It works as a charger, though...

And the dual chargers are a blessing

I love this car charger I can listen to all of my music on a jump drive the only thing i do not like is the words are small and when you are diving it hard to see what is playing and how to surf through the jump drive

I may return, it works great, but my daughter thinks the sound is not as good as when she using the adapter that's a cassette
