We love the MintyBoost. We think the it's clever, fun, and a great use of an Altoids tin. Since we love the MintyBoost so much we were thrilled when we spotted its upgrade, the MightyMintyBoost. Follow this helpful Instructable and charge your iPhone via the sun with the MightyMintyBoost.
For Instructables user Honus, the MintyBoost was definitely his first choice when it came to a charger for his iPod Touch, but he knew he wanted to take it further and do something nice for the planet by making it rechargeable and solar powered (which saves you from burning through AA batteries). Enter the MightyMintyBoost, which took him around an hour to build.
Several materials are required in addition to the Altoids tin, these include: a MintyBoost kit, Lithium Polymer battery charger, 3.7v 2000mAh Lithium Polymer battery and a small solar cell. Since you are working with electronics some of the tools that are required are a multimeter, soldering iron, and wire cutters.
We love that the MightyMintyBoost will charge via solar, USB, or by being plugged into the wall making it a very versatile little emergency battery pack. We also love that the Velcro design allows you to attach a larger solar cell to your bag when camping providing you with enough power to fully charge an iPhone in about 5.5 hours. Since this is a fairly simple project to build and we also think this would be a great gift to give as a kit.
