Just wondering cus like wouldn’t it be more convenient to just plug your phone into the wall without a brick, or like cheaper to build a pc without a power supply? why do these devices need DC but lamps, fridges, fans, most household appliances can run off AC?

Batteries are only DC.
Alternating current is much easier to transmit long distances with minimal loss, DC needed a large station every mile, it wasn’t economically viable to electrify countries with DC.
