The Power Supply Problem #927
Description

The explanation makes it sound like the problem is with the Raspberry Pi.
The problem is that the USB-C chargers are not multi-port power supplies.
Traditional multi-port chargers often enter a reset state when a new device is plugged in,
renegotiating power delivery to all connected devices.
This can cause a momentary interruption in charging.
The "reset-free" feature aims to eliminate this issue by dynamically allocating power without a reset,
even when devices are plugged in or unplugged,
as long as the total power draw stays within the charger's capacity.
There are very few devices which do not glitch, and they do not advertise very well.
The anti-glitch behavior in marketing speak is called "Reset-Free" or "Non-Renegotiating" power allocation.
You might think that introducing a battery would fix the problem but
even most pass-through batteries will have a brief loss of power.
The following devices are advertised as being "reset-free".

Even these devices when working with higher power may glitch when switching.
