Carrying a portable battery is a great way to keep your mobile device charged away from the grid. But if you are like me, sometimes the battery is not fully charged and ready. A new type of sports rechargeable battery, called AMPY, hopes to help solve this problem, use your body's movements, and charge the battery on the same day. AMPY has been created by a group of developers and designers in Chicago, USA. AMPY is a wearable device that captures energy from your movements and turns it into electricity to your phone or any USB-powered device. AMPY captures your kinetic energy and stores energy when you move, so when you need it most, you can charge your smartphone. AMPY charges iPhone, Android phone, and any other USB powered device.
AMPY stores the lithium ion battery you generate internally. Just plug your smartphone or wearable device into the USB port and start charging. AMPY charges your device as fast as a wall outlet. AMPY's internal battery stores about a week of exercise and stays available for months. You can also recharge AMPY, use a wall outlet, and if necessary use a micro-USB port on the top.
