Wallet, mobile phone, door key, and coins are my possessions in my pocket when I go out. I do not carry a power pack except for a special occasion because the whole bulk of power pack is inconvenient to carry out. I have tried to resolve that inconvenience. After due consideration, I got an idea from a cake cut in five pieces in a bakery, which is sold by the piece. Similarly, a mega battery can also be divided. So, users can have its separate units with them according to their need. That's why I have designed 'Torta', four-pieces of power pack.
