There are few feelings capable of leaving some as dejected as having a smartphone with less than 15 percent battery and a full day’s worth of activities ahead — be it an eight-hour work day or weekend outing with your friends. Considering the fact that 15 percent will likely drain itself completely before you even get to your desired location, you don’t simply want a portable charger, you need one. But who wants to spend upwards of $50 on a power bank from Radio Shack?
Certainly not Instructables user Sethaulton who devised an incredibly savvy method for assembling their own portable USB charger out of nothing more than a couple old Altoid tins and some small solar panels. Sethaulton’s finished product — a fully-functional USB charger with an additional power bank — is the best solution for not only keeping your phone charged throughout the day but doing so on the cheap.
To help you get started on this project, we’ve gone ahead and sifted through the Instructables walkthrough to piece together an exact list of tools and materials needed for the build. It is worth noting that this particular walkthrough requires the use of a soldering iron, so it’s imperative you either know how to use one — or know someone who does who can help — before attempting to construct this solar charger. Here’s everything you’ll need to get started:
Tools:
