There are some battery powered sub systems/ card available but you are limited
by the capacity of them which is not that great.  For all important computer
systems I use APC smart UPS's connect to a large adaptor block that hold
around
9 sockets with the APC unit being 1000Va.  I did have a 2k2 VA but the
batteries along with the main board failed and APC do not have spares so
switch
since then to 1000va units for my and my wife's requirements. The batteries
last around 5 - years before replacement and I have found 3rd party sources
for
the batteries for around 30 pounds instead of the 100 or so for the same thing
but with APC branding.  It takes less than 5 minutes to swap over and you can
keep the UPS running while doing it.

Note that printers are not connected the the UPS but router and primary hubs
are.  I did for a while also have a Pi3B+ (plus Hard drive) also connected to
it when running 24/7 but switched the jobs over to my main system and
discontinued the Pi despite late last year buying at great effort a Pi4B 8Gb,
240 Gb SSD all in a Argon 40 case to act as a back up but never used it - must
remember to sell in on Ebay.
