Customer Ratings & Reviews

I use this for my home theater, gives my peace of mind and allows me to shut things down when power goes out

Absolutely fantastic! Highly Recommend! Great for my home office.

Just as described works great. Would recommend to a friend.

Using to support cable modem, firewall, switch and wireless access point

Works great - highly recommended to buy. No issues.

Not too long after I set it up it did its job and with a 500.000$ coverage you can't go wrong.

It's always good to have a backup in the event of a power outage but it's unfortunate most backups won't last very long in providing power. But enough to be able to power down without losing data.

Just what I wanted. It will be used for my home network and security.

Was a good unit, did what it was supposed to do but if your high end equipment is sensitive,xbox plays ration etc... then get a UPS that power factor correction (pure sinewave), it will grearly extend the life of this equipment... no buzzing from the stepped wave.

Just great!!! Really slick and easy to setup 100%!!!

It took just a few minutes to get this setup. It is a nice backup for WFH and quick power blips.

The UPS has kept our internet modem up during continuous brown outs.

No problems at this time hope it works when we really need it

Good value for a high capacity ups. Better value than other brand name devices.

get it work with my ds918+, support DSM, and can safe automatic shut down during power outage.

Very good UPS. No problems at all. Would buy again.

I had an APC that the battery had eventually failed. It was almost cheaper to buy this one than to get batteries shipped and replaced.

The battery back up works fantastic - We are very happy with the purchase

Good unit with ample shutdown time for a small server in the closet and accompanying network gear.

After a little over a month, the UPS started to make a high-pitch whine (my guess is coil whine from the charging circuit) and reporting battery life of 55% despite having no power loss to the mains power. Tried to contact Cyberpower support, which they were decently quick to respond via email, but clearly did not want to read over any of my details or issues very clearly. After a bit of back and forth, they determined the UPS was working fine, except the issue they were trying to solve, was not the issue I was having. At this point I'm under the assumption they are not going to do anything to rectify the issue. As far as the UPS goes when it was functioning, it was okay. It's a little on the cheaper side and should've been a warning sign to begin with. In general, the consumer UPS market kinda sucks and you get taken for a ride in terms of price for what you get. In general, a good UPS comes with voltage regulation (in the case of a brown-out), simulated sine-wave output, and some sort or power bypass for when voltage from the wall is good rather than passing through the battery, which this had all of those, the quality and ultimately the companies lack of customer service has turned me away for good. Cyberpower's customer service has left me with a $170 paperweight, which at least I can get a replacement battery for $105. This is my 2nd Cyberpower UPS that's up and failed me within the past year.
