The SmartUPS2000 draws 32 to 35 watts depending on the
actual mains voltage I suppose.

That feels about right for the warmth of the case of mine, I used to run
a switched APC PDU on the output of the UPS, so I could remotely control
8x IEC sockets with various IT kit, but that ate a similar amount of
power to the UPS, and I eventually decided it wasn't worth it.

At one time I had a total of five UPSes in service

I just have the SU2200 in use (but I have a spare SU2200 and SU1400).
