OpenWrt One how to power it

Hardware Questions and Recommendations
1

Hello,

I followed URL on index page and bought OpenWrt One router.
Unfortunately seller does not sell power supply.
I checked wiki page and was looking for 30W with PD and recognized that most of cheap PSUs do not have support for 15V profile or support is unknown.
Reliable solution would be Raspberry Pi PSU but it costs almost half price of the router.

As I have simple +/- 12V 5A PSU I decided to connect it to type-c but according to specification it will not work with router as it requires PD profiles.
OK, I can take 2 wires and connect them as passive POE and there is 5400B which is 12V so great. But as I found later it is output. Input has to be 36V+.
So I am just sitting and looking at this beautiful blue box and asking myself WHY my old Linksys router, my Fiber converter and other devices have beautiful 12V DC without any profiles but this one not.
And in wiki there is just 1 line. What architect was thinking designing it.

OK I am not very experienced user, and OpenWrt is about suffering so fine I just forget about all my findings regarding POE and PD specs and asking for advice here.

I am typical internet user and want to use OpenWrt One for Internet surfing with SAMBA share on M2 SSD (I know how to configure it) and I do not have server environment with POE support and do not want to buy expensive power supply.
Want to know if anybody using OpenWrt One router with connection to 12V PSU and it works stable. How have you connected it?

A basic 48V mid-span PoE injector is pretty inexpensive (~$10USD). Or a USB PD adapter should be pretty common and easily available on most electronics retailers' sites.

The specs are clear, either USB-C PD with 15V/ >=2A XOR active PoE according to 802.3af/at (NOT passive PoE!). Anything else will not work and has a high potential for permanent damage.

If I look towards Jack Ma's market places, I see 65-67W GaN chargers including USB-C PD and 15V/ 3A around 10-15 EUR delivered. I have not tested them on an OO and only cared about other PD profiles (20V or better 28V) myself, but there are options claiming to meet the specs.

If you have other uses for a 4-5 port Poe switch you can power the OO on eth0. IIRC mine ran about $25Cdn delivered.
