Visual Cellphone Charger by 梁淑怡 from china

Cellphone needs several hours to be charged. The screen of cellphone is black in the meantime.We always light up the screen to learn how much the cellphone is charged when we are in urgent need of it.This behavior issues in loss of buttons and decreases life span of buttons. So I add four small light to the line of cell phone charger as power indicator for people to see the power status immediately. It can also remind us of unplugging the charger when the cell phone is fully charged.
