   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.
