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
Computers and 3D printers use switch mode power supplies. They don’t care if the inverter provides a square wave or a sine wave.
