I think it may be dependent on thhe ups. I have a 625 WA cyberpower on an 
rpi4, and I believe its more truthfull. Is this helpfull?

It has to hold up the pi, but only long enough for the 20kw nat gas fired 
generac outside the back garage door to start, nominally 5 seconds 
according to its -wall broadcasts. It shuts down if unplugged in only a 
couple minutes, but will not accept a longer timeout. It does do the job 
I bought it to do. The pi's draw and the interface card is about 13 or 
14 WA.
