This would be great if it worked consistently.

In reality, extensions work in some browsers but not others, on some websites but not others, and with passwords at least you can fall back to copying and pasting, or even typing, if auto-fill isn't working in the context for whatever reason. With a passkey not only are you SOL, but it will delay your ability to move onto the password option if there is one.

The devils in the (implementation) details.

It looks to me like you have to replace the whole $600 unit in 10 years rather than swapping out just the battery. I'd rather not generate that ewaste.

I would love to know how you found that one, so I can look one that supports 60 W (12 V 5A). If i search that model directly, i can find it on APC's website, but no combination of search terms brings it up otherwise, not router ups, not laptop ups... All I'm getting are the standard ups models with 120 VAC outlets.

How would you wire the barrel style adapter directly to the battery, and charge it at the same time?

You can install nextcloud on any file system afaik. Mine is btrfs. But yes, I've had unrecoverable database corruption with power failure. It uses mariadb for the database.

Thank you, I think this is basically what I'm lookong for. I'll just need to find an adapter from car outlet to the correct barrel adaptor.

EDIT the only thing that would improve it is a user-serviceable battery.

Thank you that is a great insight and may be what I do if I can't find an elegant DC solution.

How did you wire the battery up to the router, with the car battery maintainer attached?

I'm pretty sure that the UPS failed because the battery was 5 years old. The manual specifies needing to replace the battery every 3-5 years.

I double checked the router and the power supply (which is medium-big size) says 12V 5A, which comes out to 60 W

I can do this, just trying to optimize away some unnecessary power losses to get longer lifetime out of the batteries.

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

This is my router: https://www.verizon.com/support/verizon-router-cr1000a/

 

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?
