能量石 / Energy stone


Energy stone is a kind of portable power energized by swinging. Our whole body is in "a status of motion" when we are in a walking tour or wilderness exploration. So as long as energy stone is tied on knapsack and connected to a mobile phone, we can charge the mobile phone while walking. With compacted shape hanging on knapsack and without any weight - bearing, it is just like ornament on knapsack.
