In a world were batteries are becoming the new gold (every electronic device you carry has one). The biggest competition amongst tech giants is to make batteries that last longer and charge even faster.

While we wait for the big kahunas and the geniuses they hire to put together what will literally save us time and energy someday, a company wants to put your own energy into work.  Meet Ampy!

Ampy charges your phone as you move and according to the makers, an hour of exercise will add 5 hours battery life to your phone.

If you are less active, you can charge Ampy using your old chargers too. Ampy also comes with straps to hold it in place – on your arm or leg, and is sweatproof. The makers are so helpful that they give you a free app and even tell you the best places to strap Ampy to.

We very much wish to see inventions like this in the future that will be powerful enough to charge almost every device you want. e.g your electric car! Kudos!
