Does dell wd22tb4 thunderbolt 4 dock comes with power supply (i.e. the power adapter / power transformer)

Absolutely, my Dell XPS-17 is successfully powered by my WD22TB4.

Is this compatible with a non thunderbolt 4 port? I wanted to get a dock but get one that's future proof. I have a razer 15 with a usbc port

Yes, but it is best for a Thunderbolt 4 port.

How much power can pass through the 2 thunderbolt ports?

Type C ports supply a maximum of 100W.

Will the wd22tb, tb 4 version, work with a thunderbolt 3 computer?

I haven't tried it, but my understanding is that TB4 is backward compatible to TB3.
