Enbies and Gentlequeers, may we present to you: the USB-C killer five thousand.

No power delivery, no negotiation, just 12V straight to VBUS

You surely wouldn't regret having a USB-C plug with 12V on VBUS around.
@jpm does this do fast charge?
@arichtman
It does drop a massive charge rather quickly.
@jpm
@arichtman @jpm nope. i have power bricks like this. they came with the single board computers that are specced to take un-negotiated 6-15v straight to the usb-c vbus pin
@arichtman look it’ll reach end of charge pretty quickly, but it may also involve smoke
