The only limitation that I ever saw was - if you’re using a USB-C to USB-A cable to connect to your charger, the deck will say “charging slowly” while pulling absolutely nothing. It will only pull USB-C PD power. If you have a huge battery bank that can put out tons of 9v power on a quickcharge A socket, too bad.

The deck uses standard USB PD protocols to request power, so yes, these should work.
Worth noting, the Deck used to be unable to charge using PD chargers that were rated at less than 40W, this has been fixed in a firmware update and it is now able to correctly request power from any USB PD charger.
To charge while playing, a PD charger with a 15V mode is required, but any PD charger that can do 5 or 9 volts can still charge the Deck while idle/sleeping.

USB-A, per the specification, is only supposed to provide 5V max. Qualcomm Quickcharge violates the USB-A specification, so only other devices that are designed to violate the specification and thus be compatible with QC will charge faster.

There is no limit to when it will charge, you can use a lower power charger to extend your runtime - I use my 9V 2A (18W) Pixel 4a charger all the time while playing. Anything higher than 25w will keep you playing indefinitely, as that’s pretty much the limit for what the deck can draw - 15W TDP and 10W for the screen, but obviously if you draw more than your charger can output eventually you will run out of battery.

Not really that simple. There are lots of other things consuming power, but otherwise you’re correct.

That “10W for the screen” includes them all.
When you reach the 15W TDP limit with the screen at max brightness (on the LCD version), the OSD will show you drawing about 25 watts, and it’s measuring it directly from the battery. This also matches what people have reported for the power pass-through mode measuring from the wall outlet - once the battery is fully charged the Deck can power itself directly from the charger, and at full tilt, it’s about 25 watts.
Sure if you really want to start separating them all out there are things like bluetooth, wifi, speaker amplifiers etc, but compared to how much the backlight & screen controller draw, they are pretty much drops in the bucket.
