Hi, Sorry that we don't have a car charger for the Spark, however, you can consider the Spark portable charger for traveling as well. Please see the link below. Thank you for the support.

What's about a small car inverter, it gives 110 VAC to charge pretty much anything you would need. The cost under $50.

I have a built in inverter in my Jeep but doesn't work with the charger that came with the fly more package
I use the second one listed here. Works great, it can actually charge two batteries and the battery on the Spark (via USB) at the same time. I did not get the fly more combo so use this with a $10 12 V power supply fitted with a cigarette lighter socket when close to a wall socket.
