You Can Now Jog And Charge Your Phone With This Device

A new gadget called Ampy, just might be what could give a new meaning to the healthy energetic feeling from playing sports.

Ampy captures and stores the energy you generate through exercise which you can then use to charge your mobile devices.

According to the company's Kickstarter page, the small lithium ion pack which can be placed in a pocket or worn on an armband, transfers kinetic energy for use and later charges devices just as fast as a wall charger.

Kinetic energy generated from walking, cycling, jogging — just about anything you do on your feet — can now be put to use without leaving a carbon footprint.

Ampy comes with a corresponding app that tells you how much energy is in the reservoir: normally one day's worth of walking provides three hours of smartphone charge and 72 hours of juice for your wearable tracker, Malay Mail Online reports.

The same can be accomplished in about one hour of cycling, according to the company's Kickstarter page, and 30 minutes of running. Smart watches get about 24 hours of juice relative to the aforementioned devices after the same amount of exercise.

It's not a brand new concept: Tremont's nPower Peg, a "human-powered charger for handheld devices," retails for US$130.

Ampy, which is smaller than a smartphone and fits easily into a pocket and has a significant advantage in terms of portability over the nPower Peg, which measures 27 cm. And in the same area, more tiny devices could come to market in the near future with Zhong Lin Wang unveiling his research about transforming "everyday motion" into a power source through a "triboelectric nanogenerator or TENG for short" earlier this year and anticipating market-ready devices within five years.

The Ampy Kickstarter campaign doesn't end until November 10, but Ampy has already raised over US$130,000, well above its goal of US$100,000. It can still be pre-ordered for US$85 and shipping is expected in June 2015. Orders outside the US should add US$15 for shipping and handling.
