Tactile Power Bank / Mobile Peripherals

We propose a new design of power bank with tactile features allow users can immediately know the power condition. This is a universal design concept. Not only for common users but also provide a directly tactile clue for the visual impaired or old people.
The physical raised dot presents the power condition is full or empty. For example, if there are three raised dots on the top it means only 60% power is left. On the other hand, we use green light as a visual message to increase the Identification.
