Ringcharger / the portable cellphone recharger


Cellphones make great consumption of energy resources. To protect environment, we design a new way to generate power and recharge cellphones.
We design Ringcharger as a ring and a cellphone strap. It generates electric power when shaking by auto quartz technology. Ringcharger can also convert excess heat from the human body directly to energy. The energy generated will be saved until Ringcharger connects to a cellphone and starts providing electric power. The usage of Ringcharger is as easy as the usage of rings and cellphone straps. Ringcharger represents the user's sense of environmental protection when it is worn or hung on a cellphone.
