    I didn’t intend to use it on the chest freezer - it was mostly for the modem, but since I had spare battery capacity and outlets I thought what the heck.

    The power load is practically nothing until it cycles, and even then it’s fairly efficient - my current runtime is estimated to be about 18 hours, more than enough to come up with an alternative if we lose power in a storm.

    While I appreciate the sentiment, most traditional VMs do not like to have their power killed (especially non-journaling file systems).

    Even crash consistent applications can be impacted if the underlying host fs is affected by power loss.

    I do think that backup are a valid suggestion here, provided that the backup is an interrupted by a power surge or loss.

    I agree that 99.999% uptime is a pipedream for most home labs, but I personally think a UPS is worth it, if only to give yourself the option to gracefully shut down systems in the event of a power outage.

    Eventually, I’ll get a working script that checks the battery backup for mains power loss and handle the graceful shutdown for me, but right now that extra 10-15 minutes of battery backup is enough for a manual effort.

    This is why I have about five of these bad boys: CyberPower CP1500PFCLCD.

    One is in my utility room for my cable modem and our chest freezer, three back up my homelab and wifi AP, and one is for my office.

    They’ve been bulletproof through storms, and when we’ve lost power, but not Internet I can’t keep on working.

    The big thing to look for is number of battery+surge outlets vs just surge outlets. Typically they top out at 1500VA - the more overhead for what you’re powering, the longer you can go without mains power.

    A screen/display is helpful for at-a-glance information like expected runtime, current output, etc.
