That's why USB ports are always worse than a proper outlet. Just take your charging brick with you, what's the problem?
I'm a PD evangelist. Imagine a safer power delivery system that can go directly to the device you want powered. Scale that with fact most of the world could be and should be DC with AC being good just for niche applications like microwaves and mid range transmissions.
You say most of the word should be DC I till you realize that you need a 3cm thick cable to move 2000w 30m. DC is really bad outside of low or ultra high power transmission.
The calculator I used says for 48v with an acceptable drop of 3v at 50 amp (2400-2250 watts) would be a 0 (1/0) AWG or .82515cm diameter diameter wire to handle the current (oversized really but it's napkin math lol) for 30m.
Tell me you don't understand how electrical transformers work without telling me you don't know understand electrical transformers work.
Listen I don't wanna just rag on you, because you came at me with bait and what feels like an a condescending attempt to sound smart.
Do you mind just explaining what you are thinking and we could just talk about it? Transformers are fucking awesome, fucking magmatsm and shit, tons of uses. I think there is some interesting discussion here if you actually want to have it.
If you think USB A vs C outlets are a problem, wait until you see how much of a struggle getting the entire world to use DC instead of AC is like you're suggesting lol
Oh man no doubt, EVs, campers, boats, and some super scaler's get interesting with midscale DC, but trying to find codes of electricians that know about or the safety code for it is a challenge.
