Portable DIY Battery Power Bank (18650 battery)

The sun is a mass of incandescent gas, and it really wants to power robots. Good thing for all of us that robots are one of the things we love building most! But we don’t want to just build one robot – we want the ability to build different types of robots. That’s why we really love this 14-in-1 Solar Robot Kit. Each 14-in-1 Solar Robot Kit is loaded with little parts which you sort into the provided (and labeled) baggies (for easy retrieval while building). Some walk on land, some slither on land, and others paddle like mad across water. All the parts you need to build 14 different (one at a time) solar powered robots!
