Thanks for taking time and elborate.
Good point on the charger. agreed i am to idealistic.
I do not want to force my usecase on other people but what i have is a 6 port anker 50watt charger with custom made "deviceholders" in the corridor where family places its devices when not carrying or use them inhouse.
Plus the mentioned heap of >10 chargers collected historically and mostly never used.
While mobile i have a 20A powerbank for ~8 Jolla charges.
