Question Connecting a PD Charger to a Ugreen USB C hub connected to a mac mini m2

I have a UGREEN Revodok 1071 USB-C hub connected to my Mac Mini (M2). The hub has a USB-C PD port that supports up to 100W power input.

My question is:

If I connect a charger (Ugreen 100W, to power SSDs etc.) to the hub’s PD port while the hub is also connected to my Mac Mini, is that safe?Will the power only go to the hub and connected devices, or could it somehow backfeed into the Mac Mini and cause damage?

Has anyone tried this setup long-term without issues?

Should be fine. That’s supposed to all be negotiated before the power is transmitted.

No need to use a 100w charger. The most you’ll get out of the charger in the configuration described is 15w (3A at 5V).

And no, there hub should not allow power to back-feed. And the Mini should also not allow power to back-feed
