So basically their story is crap is what you're saying?

The switch charger is special somehow. I used it to charge my phone when I got my switch because it's so long. Then one day it just won't work anymore. Still worked great on the switch.

While I get what you're saying both of those are different aspects of electricity which the microchips are there to regulate. I do know some about electric systems from doing construction but not really details of electronics.

It'd be great if USA hopped on this train!

Sometimes I know that is the case, like I wouldn't expect a cheap charger to power the switch/deck very quickly, especially not while playing. The powerful chargers not working on less powerful devices is what confuses me. Maybe there's a system in place to prevent it like more wattage from the charger would be dangerous to the small device. Steam charger is brand new and won't charge my headphones which baffles me but I am pretty ignorant about the details of how electricity works.

All of my devices that use USB C charging need different chargers even though they have the same port. It's infuriating.

You'll still need different cords, unfortunately. My Switch needs it's own cord which only works for the Switch. Phone says it should only take Samsung chargers but can use the one from my Steam Deck, but that one won't charge my headphones. It's annoying. They're all USB-C but are anything but interchangable.

You've got to have something seriously good going on to make me pull off to the left to visit your gas station.
