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
How safe is it to keep a lead acid battery UPS in a relatively/loosely closed space about the size of 8 of those UPSs?
A typical UPS uses sealed lead acid batteries. Those don’t vent hydrogen unless something goes really wrong like severe overcharge or a short circuit.
Just make sure it has enough ventilation to keep it from overheating. They are usually around 80% efficient, so it will produce around 40 watts of heat with your load while it’s on battery.
