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.
