So, I got lost in the mountains this weekend, camping, when suddenly, a mountain lion jumped out of the bushes and attacked me. I finally scared it off with my tentacle arm, but only after the ferocious beast took out my legs. I was lost, immobile, and, worst of all, my cellphone was dead. Lucky for me, I always carry my solar usb charger in my backpack. This can (and will) happen to YOU! Are you prepared? Watch closely, my friend, for this video will show you how to make your own cheap, portable, solar-powered, usb power supply, and may save your life, as it did, mine.
