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.

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
