I think you spelled "yHi" wrong.

I am guessing it is pronouced, "Why high?"

And, well, I dunno why. Why not?
;-)

The reason I am so confident about the spelling, is because I think I found a picture of your power brick, with the nameplate somewhat readable, here:

https://www.global-adapters.com/new-24v-6a-12v-3a-...

I will attach that picture to this topic. The reason it is relevant is it might give some insight into how much power (in terms of voltage and current) this thing is supposed to be capable of.

Answer:
24 volts, at 6 amperes max (24V * 6A = 144 W max)
12 volts, at 3 amperes max (12V * 3A = 36 W max)

To me this seems like a lot of power for such a small sized brick, although it is hard for me to get a sense of scale (like how big it is really) from this poor quality picture.

By the way, if you can provide us with a better picture of this brick, especially one with a legible diagram of the pinouts, that could be helpful.
