USB Solar Battery Pack

Here we have a Solar Battery Charger for all your gadgets. Charger includes a 2W 6V solar panel, USB 5V step up, one 2000 mAh 3.7v 18650 Lithium battery and a TP4056 charge controller. I designed this to charge in one day of full sun, you can certainly add more batteries for your project if you'd like. This can also be charged via the micro USB. Parts snap together, I glued mine as I don't plan on opening it. However, my first prototype was not glued and is still in holding up well, even printed in PLA. I printed the parts in ABS for the final version at 50% infill. I did not use any supports, but this will depend on your printer. The small LED cover should be printed in clear/translucent filament and glued in from the inside using a drop of superglue. Electronics held in place with a little glue gun glue. Ask if you have any questions.
