photo of the front panel of a very complex USB charger, showing multiple ports with power output diagnostic displays. The ports are broken down into various groupings shown on the front panel, with the highest output port being a group of only one (itself).

   This is a REALLY good question.

   I have a similar Anker power strip, guessing it's around the same age too (couple years old?) with a 2x2 port configuration that also behaves similarly. Don't have the model number offhand.

   I can also confirm that my "Asometech" 260w giant charger box thing seems to behave like a box with four chargers in it: The ports shown in a group renegotiate when things are connected, but the one PD3.1 port appears to be completely unaffected by the lower powered USB-C ports. I didn't have a chance to try the inductive charger. It is, though, also not very portable.

   Newer multi-port chargers not only renegotiate every time, but some are extremely slow at it.
