Hi y’all looking for advice here
I selfhost a nextcloud server and a NAS for backups, and one of my challenges has been data corruption after power failures.
I went and bought some consumer UPS units about 5 years ago, which helped, but now the batteries are starting to fail, and I’m not protected from power outages until I replace them.
I have the router on UPS as well so the computers can communicate with each other that the power has failed and it is time to gracefully shut down (using NUT).
However the router itself uses quite a bit of power and I am hoping to make a smarter decision this time around when getting a UPS.
The router’s power supply is 12V5A with a barrel style jack, so i have been searching for “DC UPS 12V 5A” to try and find something compatible that wastes less energy converting from battery DC to AC for the power supply to then convert back to DC.
But the only thing I’ve been able to find are these units designed to power electric doors: https://www.amazon.com/dp/B0D8VLPRN2/
I’m not sure if this would even be safe to use with a router, and i don’t know how i would wire it up to the router either.
I think i just don’t have enough knowledge to know how to shop for an appropriate DC UPS, or if such a thing even exists.
Anyone been in a similar situation?


I went the POE route, inject poe to the router and use a POE to DC jack extractor to power the router/modem. My Poe injector is behind my UPS so it will remain powered on.
A lot of the POE options I’ve seen seem to top out at 12V 2A, can POE deliver 12V 5A?
For example, when i look at thus one, it can do 48 V but only about 0.5A, to achieve 25 W. A lot of them seem to be like this. https://shop.poetexas.com/collections/poe-to-dc-power/products/gpoe-48v25w
