Think of it as a Minty Big-Boost. Micah and a buddy are leaving on a cross-country trip and they don’t want their handheld gaming systems to run out of juice along the way, so he put together this battery powerpack using 12 Volt 7 AH Lead-calcium battery. They’re hoping to get some 30 hours of juice out of the thing.
