Meeting with supervisor - Power supply

To have a battery powered device, the plan was to use a rechargeable battery and build a circuit for it. While progressing with the project, I came out with the idea of using a power bank to power the Raspberry Pi.

Power banks meets the project specifications as it is a powerful probable solution for keeping the Raspberry Pi powered everywhere, also rechargeable. The advantage of using power banks that some of them have a display screen that shows the percentage left, which is useful to find out how long left for the device to be on.
