Review on Interactive UPS CyberPower UT650EG by Jnis Banders ᠌

I don’t really understand these same UPSs, I bought this product for myself solely so that during a power outage I could comfortably save my work and turn off the computer, and everything seemed to be ok at first, but after a few months everything changed, but I don’t know why, at the slightest, momentary power outage, my Imac 27 2022 also turns off, although the instructions for this UPS say that it is with this UPS model that my computer can work up to half an hour (!) In general, I am extremely dissatisfied, now I have to go to the dns, draw up a check, examination, or whatever they have . thank you very much, CyberPower!
