My favorite road trip songs is Taylor swift songs. Much high for girls to enjoy this journey. When we enjoy songs, I should pay attention to charger, whether we have take a charger with us. Since in this trip, maybe you need to keep some beautiful scenery. The charger-300w power inverter is for me to charge camera battery. Last month, I bought this tool on bestekmall. This is just a tip for you. If you like to take photos. Have a nice day.
