Charge Battery from designers Yeon Kyeong Hwang & Mieong Ho Kang reminds us of the spring driven toys of childhood in which a repeated rotations of the key would make the toy move.

In case of drained out batteries a person either has to constantly carry a charger or get a new load of batteries. The designers state that Charge Battery removes all these time consuming barriers by letting you recharge it with simple winding-up motions.Wherever you are and whenever required these batteries could be charged up that easily.

“There is clockowork inside the spiral spring, which makes it possible to simply wind up the battery and conveniently charge it.”
