The powerbank creation is impressive, even more so if it was created out of old batteries (I mean batteries that had a poor battery life when it was in a phone).

I totally agree that we need to help our children reach their potential in whatever field they decide to roam, but... duty to give them everything they need to be successful - I do not agree there.
That will make them accustomed to being handed everything and not work to get what they need for something.
