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.
