Capacitor car charger
Print Profile(1)
Description
I saw a capacitor car on Pinduoduo, perfect for kids to play with. Since it didn't come with a charger, I made one.
Originally, there was a black one, which looked a bit better, but it was out of stock when I bought it. 9.9 for two cars.

Some wires, one 3.7v lithium battery

1. Insert the AAA battery spring contacts
