AMPY, the world's smallest wearable motion charger, transforms the energy from your motion and turns it into power for your devices. Tejas Shastry, Mike Geier, and Alex Smith met in a Northwestern University entrepreneurship class during their engineering PhDs. The trio wanted to solve a problem that most people experience — a dead smartphone battery at the worst time. AMPY is the solution. AMPY is a dual-mode motion charger: It charges from your movement and from the wall. In November, AMPY's Kickstarter campaign was funded more than 300%.
