alt Hacker NewsThe reason is because while you want to use the low end the general public does not understand that USB-C is the connector only and that various levels of power and data depend on the cable and the device at both ends.
If you sell a 10 port USB-C charged someone is going to plug 10 MacBooks into it and complain it doesnt work.
The best I have seen for what you want is

but is not cheap at all or something like

Macbooks aren't the absolute best example anymore, since 20W is plenty to charge ARM-based MacBooks in a few hours, so a 200W 10-port charger could do a fine job with 10 MacBooks.
But your point is still valid. As a nerd I really appreciate being able to use say, my 100W laptop charger or the car jumpstarter pack I have to charge up my earbuds or an electric toothbrush, since it reduces the number of weird little cables or chargers I have to keep track of, but it sure does baffle the non-technical majority that their toothbrush charger fits their laptop 'for some reason' but of course does nothing - plus the confusion when they realize they could physically plug the toothbrush into a pair of headphones, or plug two portable batteries together.
