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?

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.

Depending on the toaster it uses around 1000 watts. Pc workstation with 4 monitors could use half that. An for why it cut out in about 10 seconds. That’s probably because the toaster. tried to draw more than the ups could output. So to protect itself and what’s connected. The ups would shut down.
