@whitequark@social.treehouse.systems @derf@social.skyshaper.org Why do you believe it will not survive 12V?
I guess you should not try, because it may be out of spec for the devices, but old Nokia phones were designed for 5V charging, but were actually designed to survive 15V IIRC according to service manuals.
I'd strongly suggest anything USB to survive 20V these days, and may guess is that a lot of hardware would actually survive.

@pavel@social.kernel.org @derf@social.skyshaper.org because I design electronics and know how it's put together? it's pretty normal to use components with absolute max rating of 6-7 V if you're not using USB-PD explicitly. it adds cost for very little gain, so it is generally not done
