On another note, I am SO glad that they didn't start their video talking about the problem of your phone battery going dead.
There are a HEAP of phone battery/charge devices popping up on Kickstarter and every single one of them spends about a minute describing the problem of running out of a battery. It bores me and I stop watching. Yes we all use our phones. Yes the batteries die. I get it. Move on.
What I loved about Ampy's video is that these guys move straight into what their product does, then get into a great video that explains the product, their story and where they're at in development/manufacturing (while poking some fun at the Kickstarter video format, which I also loved).
AMPY is a wearable device that captures kinetic energy when you move and stores it, turning it into power to charge your phone or any USB-powered device. AMPY charges iPhones, Android phones, and any other USB-powered device.
