    Storm outage backup

    Needed this to protect my home built gaming PC. We had a few storms over the course of a week that kept knocking out the power. Did some research and found that this was one of the highest rated products for its kind. Since my purchase the power has gone out a few times and this gives me piece of mind knowing that I have time to power down my PC to keep it from getting damaged.

    Electric company had to spend several weeks replacing old infrastructure on my block, and in the meantime power wasn't guaranteed. Not something I wanted to risk 24TB of a RAID array on. This unit's very affordable for what it provides, and the optional software that allows for system shutdowns when the battery gets low is exactly what I need for my home servers.

    Pure sinewave unit protection for my tv. Power here is not good. Overkill, but well worth it.

    Protected PC during Storm

    I've had this product for several months now. Roughly two months ago, we had a very long outage due to a horrible storm. When the power initially went out, I had time to turn off my large PC. After turning it off, I only kept my phone charger in and I was able to charge my phone for a bit afterwards. Only slight concern is that after I powered it off, the battery backup didn't keep it's stored battery power- making it unable to be used afterwards if I needed to charge my phone again. (Maybe that is said in the description and I might've missed it.)

    This product works great! The few times my power has flickered or went off entirely, this unit has allowed me time to turn off my gaming pc, and my entertainment system safely. I couldn't be happier with it! In my opinion, it's a must if you have nice electronics.

    Easy to set up and get using. Haven't really had an outage to test it truly besides a flicker. But its doing what its supposed to so far.

    I love this new power supply I just got yesterday because it was windy and my non-sine wave apc ups would not carry my new i9 rtx 3090 gold psu computer during a power flicker. I would’ve got either brand for my new one but this one was the only one in stock and it was cheaper with the same specs as APC who have loved for over a decade

    These work well. The last one lasted at least 5 years so I just replaced with a similar model. Very easy to use just plug it in

    Have been using with a WiFi router and NAS every day for over a year. Works great and have never had an issue with it. Very helpful to avoid downtime during power outtages, especially if I am not home. Was easy to setup and use.

    I bought this as a battery backup for an iMac. It's by far the best battery backup unit I've ever purchased, but also the most expensive. It will run my iMac in a power outage for over 1.5 hours if it's not powering anything else. I've had several CyberPower units over the years and all have been very reliable and do exactly what they need to.

    Great little battery back-up. We get frequent power surges, so I hooked up our networking equipment to this. In our area the cell service is nonexistent. So anytime we would lose power, we would basically lose connection to the outside world (text, calls). I have a modem, router, UNVR, and switch all hooked up to this and it will power them for about 60 minutes. When the power flickers, this switches seamlessly to power without dropping a beat.
