Lithium Heavy Duty 2.0

This project was an update to the original Lithium Heavy Duty Kit. It was designed as a "real world" solar USB charger able to charge up most large and small USB devices. This version featured a 5W panel and several battery options. It's often referred to as the "adult" version of our popular Solar USB Kit.
