Which UPS?

[Neptune]

So Uniteruptable Power Supplies. Someone here will know what’s what, I don’t.
We have just been moved to full fibre but sadly live in an area with VERY poor mobile signal and are prone to power cuts.
Sky, my broadband supplier supply nothing in the form of a battery back up and offer precisely nothing in the way of help. I have had this suggested.

Any one who knows anything about these fandangles or other makes who cares to offer me some advice will get their reward in heaven

get one that'll run a pc and it'll keep it going for ages, bigger the better, but obviously if you want a mini form factor one it'll be a smaller battery and less run time
