That's why USB ports are always worse than a proper outlet. Just take your charging brick with you, what's the problem?
travels internationally
You've got to start traveling with one of these bad boys:
When you're advanced, you carry two: one powers your stuff, and the other is for your karaoke machine.
Just throw some backpack straps on that and off you go
Chargers are almost always compatible with any a/c voltage and only need a physical adapter to plug into a wall socket in a different country. Or bring a power bank with you
I've got a brick for EU/UK/USA/AUS plugs with 3 type a and 1 type c and an international multiplug ac/ac pass through.
USB ports on a wall outlet or power strip are usually much more space efficient than a charging brick.
They're also much less capable though. Have fun finding a USB-C PD port anywhere when you need to charge your laptop - a power outlet is much more useful.
I basically end up using power bricks for laptop and phone, and ports built into a power strip for everything else. Most stuff doesn't need full PD support (but most anker power strips actually support it, just not at very high wattage).
Does nobody have usb to usbc cables?
I don't think you can do the PD standard from a USB a port. Edit: Reading the Wikipedia page, it sounds like usb-a supports PD 1.0 but not 2.0+ and the higher power requirements.
best i can do is a usb-b to usb-c adapter :D
what about USB mini a to USB c?
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.
Tell me you don't understand how electrical transformers work without telling me you don't know understand electrical transformers work.
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.
