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

Look for devices, and read their specification sheets. They will tell you how much wattage they can support and how long they can support it for. They might do it in different units you can convert to wattage.

Do you need your devices to stay on for prolonged periods of time off the battery? Or just long enough to shut down? That will have a huge impact on how expensive your UPS will be.

You can add up the wattage of all of your devices, and see what the maximum is. Or you can get a $3 power meter and measure it empirically. Most UPS's will set off an alarm if you're drawing more power than they could support if they had to switch to the battery

Power outages are usually very short (few seconds max). Are fanless ups ok or should I stay away from it. The one I'm looking out at the moment is Eaton Ellipse eco 500

If you only need it to skip the power outage, I would look at something in the range of 800W to 1000W in an online ups.

This wattage should run your devices for 5 minutes or so, as you have quoted them. The online UPS will always run its load off on the battery, so there is no swap over time. Other types will be fine for a PC or normal electronics, but the hitch in power could cause a defect in the 3D print.

Fanless is great, they are quiet.

Usually the fanless ones have power power restrictions, or only kick in when the power goes off
