    I work for a university and several of our rooms have "weird" things happening: equipment needing rebooting every couple weeks, things that kinda, sorta stop working, etc. I put these in 2 of the rooms and all of the issues dried up, like magic. Very useful!

    Lift chairs are traps if the power goes out.

    The price is great. We bought this as a battery backup for my father-in-laws lift chair. It does the trick when the power goes out.

    Highly recommend for in-home network devices such as cable modem, WiFi router, hubs, gateways, etc. This way, if power goes down, the network stays up. CyberPower is a good reliable brand, and I've owned several since 1995.

    My power went out and I ended up plugging my fan into it. It ran for about 20minutes. So it will be fine for computers and other things to give you a minute to save files or safely turn off your device. I have another one I'm using for my fridge. I plugged a little electric single burner to it and it popped the breaker. So it couldnt handle those two appliances. But they have larger ones to accommodate your needs.

    Have always used the extended backup battery system. Great for those times when you have no electric but a need to use computer.

    I live in a rural area where brief power outages are a monthly occurrence. This UPS keeps my computer active until I can properly shut it down without fear of losing data. Quick delivery, good price. Would like display showing running time remaining but can't complain for the bargain- basement price.

    This battery back-up has already come in handy when I had a power interruption being on the phone at the same time and didn't lose the phone call. Great choice, would highly recommend the CyberPower battery backup...

    Looking to be a good investment. Already came in handy when the power went out. PS4 and PC stayed running when everything else shut down allowing me to do a proper shut down. Honestly not using it for extended battery use so I can't speak to that.

    A perfect addition for that added security for your computer or gaming setup. Keeps a nice charge to prevent projects or gameplay from being interrupted if the power goes out.

    Since purchasing this item it has done its job. Had several brownouts and it saved my computer. Worth the cost.

    I use this for my 65" television and PS5, works out really well. The battery backup makes me feel safe when the lights flicker during storms (PS5's are hard to find, let alone replace).

    I bought this when my last back-up battery (leading brand) died just after going out of warranty. The battery has worked as expected through several storm-related power outages and allowed me to finish my work and shut down with power to spare.

    I have these all over my house, because the power in my area always glitches when it is windy. This has saved my electronics time and time again. Also a side note that they hold enough juice to charge your cell phone in a power outage.

    I work at home and depend on my computer. The day after purchasing the CyberPower back-up system the power went out. The computer stayed up and no files were lost -- it worked faultlessly.

    Now that I am working a bit more remotely, we decided in invest in a battery back up system. For a light user, this is exactly what I needed. I've not had to use it yet (fingers crossed) but it is simple to set up and charge.
