Yoyos have been really popular with kids. Very rarely would you see an adult spinning it, but not anymore. Here is a yoyo mobile phone charger concept that we hope will be seen in many hands. Designed by Emmanuel Hanson, the charger works by harnesses the kinetic energy generated through playing a yoyo. This energy is then be used to juice up your cellphones. Isn’t it exciting to perform various tricks with the yoyo to keep your batteries charged? Swing it in the air or toss it down, it will generate power as long as it keeps moving.
