Choosing The Right UPS
-
I would say that unless power cuts are extremely common in your part of the world, and/or you have mission-critical equipment that cannot be turned off, a UPS is a waste of money. A UPS large enough to run heavy hardware for a significant amount of time (an hour or more) does not come cheap. I have surge protectors on all my equipment, and that's it. Power cuts are extremely rare in my part of the world, so I don't really worry about them. I use laptops (attached to desktop monitors) for my work, so they have a "built-in" UPS. The local telephone company provides internet over fiber, and if that ever goes down (it hasn't yet...) I have a large enough data package on my mobile phone that I can use it as a backup. The only things that I would need to power via UPS are the Wi-Fi access point and the fiber router, and for those tiny loads any UPS will do. Adding the desktop monitors would require a slightly larger UPS, but for the few minutes of power cuts a year I can work quite well with the laptop and a mobile phone connection.

I agree with Dan, for all the same reasons. I lost power during hurricane Beryl which drained the UPS batteries. The only thing critical was WIFI access. My laptop and it's battery system did most of the heavy lifting for internet access via a computer. Used my Jackery battery and small battery bricks for small TV and phones.
