Yeah, but that doesn't mean you want to expose them to brownout conditions when your UPS is depleted. If the power is continuing to flip on and off, it's better to just leave it off if you don't have the battery to prevent even short interruptions. A good UPS can do this automatically for you. A cheap one will just stay off and let you respond to the outage.

> This is such a weird presumption.

It wasn't a presumption I was making for all users -- but an example of why some users might not want auto-restart as a feature. Of course, if you want auto-restart as a feature, you can buy a UPS that has it as a feature and turn it on.

> they don’t apply to most users, and I’m talking about smaller UPSes.

Yeah, I know the situation: Someone has a network closet on a budget with a UPS they've sized to get them a few minutes of runtime. They put a UPS on the BOM because it checks a box. So they buy a low-end UPS that either doesn't have the feature, or it doesn't work right.

The solution is just to buy the right UPS for the thing they were trying to do... and test it.
