I wasn’t sure where to classify this…

  I have a regular construction generator I want to use as an emergency backup, as well as a battery backup UPS on my computer.

 what good is the generator or battery backup going to do for your computer when there has been a hurricane and more than likely the cable or whatever you use to get internet is down and probably will be for a while?

the small generator that you have now is used to power small things......lights, fridge, freezer, fans stuff like that.    

when a hurricane comes, you could care less about if the computer is up and running.         you will now have to deal with hot much hot water do we have left ?   what you wouldnt give to have ac right now.   running out of clean clothes.    cant cook on the stove as the small generator cant power that up, so have to use the grill.......and hope we have enough gas to cook with.                  do you have a well for water ?   if so, how are you going to get water ?

so , as you see.......a computer will be the last thing you will need to worry about.

i sent you a pm also....and feel free to contact me as i have plenty  of info i can pass on to you since you are new to this .

As one living in the South myself, I understand your concerns. I use laptop computers and keep a couple of batteries charged up. I can charge my cell phone through the PC USB and use it as a hotspot for internet access. Problem solved. 

@riley804 When you are home for 10 days with no power, you get bored.  The generator I have is a large construction generator that will power my minisplit AC I have for my gaming room/office, which is where I’d be living in the event of a hurricane power outage.  It will also power my chest freezer, and my refrigerator, as well as power for my computer.  I have quite a few VR games I can play without internet, as well as a movie server with tons of movies and TV shows.  I just want to make sure I don’t smoke my gaming rig with dirty power.

My generator running on propane will kick out 6800W nominal.  My minisplit AC runs on a 15 amp circuit, so even if I dedicate the full capacity of that circuit in power (accounting for the start up draw etc), that’s only 1800W.  I still have 4000 to play with.  So yes, my generator is powerful enough to do more than just the “small stuff”

your not.

i had a mini split at  our other house for that same reason also.

For your computer, a standard UPS would work fine. Don't forget to put your cable modem and wifi router on an appropriate UPS as well. 

For your audio/video gear get Furman with SMP and LiFT. They’ll keep your gear safe through over/undervoltages and surges.

If you are also looking at long periods of time with varying voltages consider a more advanced Furman with voltage regulation.

Also, the NEC as of 2020 requires whole house surge suppressors. They’ll help keep your magor appliances, HVAC and home automation gear safer. Not a substitute for your PC’s UPS but a beneficial add-on.
