Why can my uninterruptible power source handle an entire workstation and 4 monitors for half an hour, but dies on my toaster in less than 30 seconds?

Question

Lost power today. My toddler wanted toast during the outage so I figured I could make her some via the UPS. It made it all of 10 seconds before it was completely dead.

Edit: I turned it off immediately after we lost power so it was at about 95% capacity. This also isn’t your average workstation, it’s got a threadripper and a 4080 in it. That being said it wasn’t doing anything intensive.
It’s also a monster UPS.

Edit2: its not a TI obviously. I’ve lost my mind attempting to reason with a 2 year old about why she got no toast for hours.

Here is a short video showing how an Olympic cyclist compares to a toaster. Pretty telling how much power they need to function.
