I totally agree here, but the problem isn't that you don't have a charger at home, I don't say it isn't one of the problems, but not the biggest one.
Let's say you have one but your cable is fried or broken in general because come on, it is an apple cable, they break like it is no tomorrow.
The cable that comes with the phone is lightning to USB type c, so you can't put it into a normal wall charger, you are expected to have a Mak, or to upgrade from an 11 pro or max or to have a modern laptop with USB type c and just charge it on that.
