What about PoE for 10G Ethernet? I see that there are some vendors (e.g. Ubiquity) that are offering devices with it, but I don't see it in the standards?

My question is this: what would you plug into POE that would need 10gbe?

I had no idea it could supply 90 watts or so. At that point you could power some pretty powerful terminals.

The new 14” MacBook Pro comes with a 70 watt charger. An M4 Air only gets a 35 watt adapter.

Basically seems like enough power is available to run something pretty powerful.

It's really ~71 watts on the device end (not counting any inefficiencies in the device itself). Still plenty powerful to do a lot with, but also more limiting. Especially if you don't already plan on having a built in battery to handle bursty workloads for whatever reason the device needed a 10G port for.
