Power goess off, the first UPS goes on batteries, and runs everything.
When it quits, the second UPS senses it and goes on batteries, and
runs the computer.

And so indefinitely if you add more UPSs to get more runtime.

It seems it me it would work except possibly :

(1)The UPSs might not like the non-sinewave output of the first UPS, and
(2)I don't know what kind of current they draw if they decide to
recharge their batteries from an outer UPS. (This would suggest it's
wise to unplug the outer UPS when the power goes off so nobody
tries to recharge.)

On the internet, nobody knows you're a jerk.

What's On Your Power Grid :
UPS ? -or- Alternative Power Supply ?

Maybe the Philosophical Question should be . . .

WHY USE AN "UPS" ?

* Do You Use and UPS ?

* Why Do You Use an UPS ?

From 'my prespective' living at the End-of-a-Country-Road.
I use an UPS to Safely Power Down the Computer and
wait, Wait. and WAIT ! until Full Electrical Power is Restored.
When the Lights Go Out and the UPS Beeps and Lights-Up
that It Is "ON" {Working}. My actions are simple :
1 - Close Down the Compluter Applications
2 - Power Down the Computer
3 - Turn Off the UPS
4 - Check the Emergency Lights
5 - Start a Fire in the Wood Stove
6 - Turn on the Radio and Listen to What's Out There ! ! !
- - - When the Local Background Noise is Ever-Oh-So-Low.

BUT =IF= What You Want Is an Alternative Power Supply
that will Run your Computers for Many Hours and up to a
Day. Consider some Deep Cycle Storage Batteries and a
very good Solid State Inverter.
