AMPY is the world's smallest dual-mode battery that charges both from human motion and from an AC outlet. An active day gives a user another few hours of battery life for their smartphone. A full AMPY delivers up to 60% battery life for a smartphone or several recharges of smaller mobile devices (iPods, smartwatches, fitness trackers). At the core of AMPY is the company's proprietary inductor technology, allowing the device to produce the same power as other kinetic chargers in a form factor that is 3 times smaller. The company is currently looking to integrate the technology directly into wearable devices.
