Introduction

Occasionally we have some lithium batteries in stock, and during that time we sell an upgraded version of our Solar USB Charger Kit. In general we don't recommend this for use in a classroom as lithium batteries can be dangerous when not handled properly. However, they do offer a much greater power source for recharging modern devices. We do sell all the parts necessary for this project on our website, but you'll have to source your own lithium battery.
