I use Energizer's 15 minute charger. It's pretty expensive at about $30, but it's worth every penny. The batteries are expensive. I paid a little less than $30 for 12 Energizer AAAs. I can pretty much run the car non stop now, running on 4, charging 4, and cooling 4 at the same time. I usually stop when I think the motor's getting too hot.
