pov: you wake up to receive a package with a vacuum chamber and discover that the vendor is a crackhead and a menace to society

this is a vacuum chamber. the power supply that comes with it has a type-C connector and it puts 12V on Vbus unconditionally. the pump works off both 5V and 12V, so it can pull vacuum off a normal type-C power supply. but the solenoid release valve (that lets you open the chamber once you're done) requires their illegal type-C-shaped power supply. also, not only does the chamber not support PD negotiation, it does not even have a CC pulldown.

to add insult to injury, it's using a NEMA 1-15P plug.

@whitequark at least it's not using NEMA 5-15 for 24VDC (I've seen this)

@azonenberg @whitequark I am reminded of the so called "household" standard for flash sync cables https://pocketwizard.com/products/mh3-flash-sync-cable/

Advantage: can use common extension cords and taps to connect all your flashes.

Disadvantage: NEMA 1 to 2.5mm/3.5mm cables.

@sen @azonenberg this is actually almost entirely safe in any country that isn't using NEMA 1 sockets, haha

(people still have UPSes and universal sockets and such, so not entirely)
