I'm wondering if there are any dangers or precautions to putting a
couple of UPS's in series to increase their power-on time?

Even presuming sufficient VA (=W/PF), few UPSes produce
nice sine waves on their outputs while most expect them on
their inputs. There may be problems [overheating] with the
second UPS. UPS should be able to handle poor powerfactor
draws since most computing devices are miserable.
It would be vastly preferable to put them in parallel
where you can split loads, like one for the CPU,
one for monitor & wallwarts.

That's what I was afraid of. I remember hearing something about that
sometime back, but I couldn't remember if I heard it right or what the
reason was, so I asked here.

Bad enough coping with a power outage without having to do it in the dark.
In general it's more effective to split load or use a bigger UPS. With fewYKhan said:I'm wondering if there are any dangers or precautions to putting a

That's what all the blinking lights are for - all real computers have
blinking lights right?-)

in series.
