@kaia from a professional who works in this area, anything Cyberpower, APC, or Eaton is ok. Make sure you get it from authorized retailer so your warranty is valid they’ll cover battery failure like 5 or 7 years. Eaton owns Cyberpower so they’re two sides of the same coin.
I’d get one with USB integration you can plug it into the computer and with apcupsd you can have it push the shutdown button on its own if battery gets to 10% or so for a clean shutdown. It also shows up in Linux like a laptop battery with the charge level in the tray if you want.
