Router power backup?

[Ice_Black]

I am looking for power backup for a router for at least 3 hours when the main power is cut off.

Router is 12v and 1amp rating.

I have found Eaton 3S Mini which can last about 1 hour and 20 minutes. https://www.eaton.com/content/dam/e...-pqed-dpq-3s-mini-datasheet-low-en-us.pdf.pdf

I have also found IPOWER-H https://1va.co.uk/ipower-12vdc-ups-system-p-78.html - it stated it can last 1 hour.

Can you please advise?

I've not used any small ones like those before, if I've needed anything on for a period of time I've gone for an APC UPS. One of the home ones will still be a bit overkill for what you need though I guess, if its just 12w coming off of it - https://www.overclockers.co.uk/apc-back-ups-cs-500va-230v-stand-alone-ups-bk500ei-up-037-ap.html. That will go for ~15 mins at ~400w so ~1 hour if drawing ~100w.

I have a couple of APC UPS which my modem, router, switches, Raspberry Pi's and AP run off.
They are a bit bulky so hide them out the way. I have ones you can plug the UK plug straight into.
Also powers PC, NAS and monitor so would have to shut them down if more than just a blip

I doubt a mini UPS with a single or double 18650 3.7v lithium cell are going to last long in a mains failure and I wouldn't be surprised if those devices figures are for completely idle router and of course with a brand new battery.

Unless you can can measure and confirm usage of your current router in various loads to calculate a rough runtime I would look at a larger UPS (APC/Cyberpower or similar) with an easily available 12V sealed lead/acid battery as UPS batteries need changing every 3 to 5 years. They're not much more expensive but will give vastly longer runtime.
