I bought it to connect an OLED TV, a soundbar, and a TV box. Total power is about 200 watts. It is quite small in size, relatively good build quality, and it is the same size as the 850 model, and you can use a 7 or 9 battery instead of the 5 battery it comes with. So, after having it for a month, I decided to test it. I unplugged it and it shut down in less than a minute. I tried it again after it had charged, and the same thing happened, this time without any notification that the battery was running out. I sent it for service, they checked it and said everything was fine. I got it back, borrowed a watt meter from a friend. I connected two laptops with the meter and saw that they were drawing 100 watts and it lasted as long as it was supposed to, about 15 minutes. Everything seemed okay. I connected it to the TV, tested it again, and it shut down in half a minute without any notification that the battery was running out or any error message. I tried to record a video and while the UPS was running, the TV shut down (!!) and turned back on by itself after a while. That's when I realized that the waveform it produces is bad and it can't really work with the TV. In order not to damage my TV, I returned it and got a refund. I confirmed it with a multimeter, where it showed 160V at the output with a non-RMS multimeter, while with an RMS multimeter it showed 235V. One would say it's normal, but my non-RMS multimeter shows accurate measurements with all the other UPS devices I have seen. I assume it produces a very poor waveform and simply blocks the UPS, causing it to shut down completely, so I wouldn't recommend it for any use. However, it works fine with a computer, which has better power supplies compared to a TV, etc. It's a shame because it looks good on paper, it has the most protections in its price category, but obviously they had to cut corners somewhere. I found a used APC and connected it to the TV, and everything works fine now.

The connection cannot be made with USB, it requires a different cable. If you find the cable and connect the UPS to the PC, Windows will install the battery for Windows and every time the PC goes into sleep mode and then starts again, it will show a BSOD, usually driver irql driver less or equal, and it will restart.

On the manufacturer's page, there are no drivers available for this specific model, and it does not show the option to download the Personal Panel program, as it does for other models of the company.

If you eventually connect it using the CyberPower Personal Panel, which you can find (but not on the model's page), every time the PC goes into sleep mode, it will still show a BSOD.

The ut1050eg and ut1200eg have the same lack of option on their page, they do not have the option for personal panel (while the ut850 does), unfortunately, when I bought it, I did not pay attention to this detail because I believed the specifications that said it can be connected to a PC.

Stay away from this UPS.
