A complete race track with two juicers, a Hot Wheels Sizzler's case with slots for four cars and 2 cars. Both chargers charged the cars, but the one without the label seem to do better. Both cars did take a charge. The green one didn't seem to hold a long charge. I did just run it without racing it. I don't know for sure how long they would last. I did not assemble the entire track. It requires two - four D batteries, not included. The box is pretty rough!. Let me know if you need anyone information.
