Question about a POE-only appliance

I need some help in sourcing an appliance to provide POE for some Primex clocks that are going into a new construction area. Does such a thing exist, even?

We have a construction project which has multiple Primex clocks going into the new area. These clocks are only powered by the network, and are kept synchronized via radio waves.
At the last count there were 65 of these devices to be connected to the network power, and because they don't use network traffic, it seemed a waste to use 9300 switches to just provide power.

edit: I've been suggested to look through Amazon for POE injectors. I guess I was overthinking the issue
