That rating from that PSU will be the max it can supply, it is very unlikely that a consumer router is pulling 5A.
Your router firmware might even expose its power consumption if you are lucky.
I have the same/similar setup. My wall-warts are just plugged into the UPS.

I was just thinking the same thing. I was also thinking you can get a wide input voltage buck converter on amazon for cheap and use a bunch of cells in series as the UPS and the buck converter spits out 12V until it cant anymore. Then just wire up a charge controller to charge and balance your lead acid cells.
