I’m looking to buy ups as I have few power outage (last between 1 to 5 seconds max) where I live but I have never used one so don’t know what specs should I check for

Ideally I will plug my 3d printer (about 100-160w when printing), a pi 4 with nvme drive (no idea of wattage) and a mini pc with n100 processor (around 10-20W)

Thanks for your advices

    I can’t help much on the power draw side of this question, but one thing to look out for with a UPS is some sort of communication option. (Usually NUT over ethernet, but there are some USB options too.) Most modern UPS brands will have a plugin you can install on your Raspberry Pi and Mini PC that allows your UPS to signal, “Hey, I’ve got 3% of battery life, you actually need to gracefully shut down now.” It’s mostly useful for NAS applications with spinning drives, but it could help save your Pi’s SD card potentially.

    It’s a pretty standard feature these days, but the cheapest of the cheap will omit it.

      I have nvme setup on my pi 4 (I know it’s overkill for that purpose but already had pi setup like this prior to klipper), that being said I will definitely look at getting one with communication control even if power never goes down for more than a couple of seconds
