Solar USB Charger w/ Voltage Monitors

thingiverse

Great project for charging solar chargers! This charger will charge any USB device you need to power. Two voltage monitors are included, one for the charging input (solar panel or wall charger) and one for battery voltage so you can tell when it's running low. The solar panel is also on a hinge, allowing you to get the best angle towards the sun. Voltage meters plug into additional ports on the Lithium Ion Solar Charger with female connectors or can be soldered directly. All wires are run neatly in a channel under the voltage meters for a clean look. I'm sure you could build one of these chargers using cheaper components, but I had all of this stuff already and reused it from some old projects to make this charger. Enjoy!
