It'd be good if consumer UPSes had DC output for this reason. If only laptops could be standardized in terms of voltage requirements.

A lot of them are pretty similar; 19V - 21V seems quite common.

Until recently phones were standardized on 5V. Now, it's a mess again. :-(

I vaguely recall seeing someone modify their UPS for this in their "homelab", such that they were running a 12v cable modem, router and WAP off of the UPS battery pack directly somehow. They had dramatically longer run time from a full charge. (Well more than double, I think.)

Ooh, imagine a NUC or such small enough machine running off of USB-C Power Delivery. 65 Watt power budget easily. I guess a Raspberry Pi would count as that?

Then a battery pack could provide that, as DC.
