Lithium Heavy Duty 2.0


This project is 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 features a 5W panel and several battery options.  It's often referred to as the "adult" version of our popular Solar USB line of kits.

There is currently one version of this kit available, with options for a 2600mAh and a 6600mAh battery.
