Customer Ratings & Reviews

Used to power a Synology NAS. Works great. Powers for around 30 minutes and can send signal via USB to do an orderly safe shutdown if still powered by battery after x amount of time.

Have had several of these for different projects. Usually get the 1500VA to avoid issues and it makes battery replacement (every 2-4yrs) easier since they all use the same size. Sine wave is an extra plus, but POE switch not browning out and causing issues with attached devices on the smaller 650VA initially installed is a time saver in and of itself.

Good PSU dont not beep all the time. Great so for...

Great system. Ive already had pwoer issue and it kept my computer running so i could turn it off properly without having to worry about my storage device being corrupted

Happy with purchase. Functions as described. Using it to power sensitive electronics in my home studio.

This UPS has already saved my computer from data loss and possibly worse. No sooner did I set this up with my new computer when the power went out, bounced back on and the out again. That is the worst case scenario for crashing computers. The sine wave UPS didn't flinch. My computer never noticed the power surge as if it never happened.

I can tell you that it’s hands-down the best device I have used to date to protect high-end gear such as high-end AV gear mission-critical devices.

As summer storms are frequent now, I wanted a UPS to protect all my entertainment electronics. I chose this Sine Wave UPS as I didn't want the risk of various components having problems with the stepped wave forms of most UPS systems. This one will carry through until my whole house generator comes online if the outage lasts more than a minute.

Great UPS so far. Zero complaints and easy to use. Love that it’s a true sine wave for better power delivery if you lose power. Have WiFi devices and security cameras hub attached to it has en estimated run time of 2 hours so plenty of time to do anything via internet if power goes out as well as still eyes on house.

Works as intended. I have 3 Cyber Power UPS and they always work fine.

Good UPS for the price. Access to the maint log is a bonus. Perfect for the 3d printing and control equipment this is backing up.

My older UPS box had a bad battery and would not handle the VA-Wattage load of my new system, I repaired the old unit and added the new one with a larger VA-Wattage ability. Works great!!!

Well made and has more features than competition for the price point. I like the app that is easily downloaded to my MAC that provides a summary of the unit's performance, power conditions, and history. Some of the plugs on my equipment are turned sideways, so they cover up some of the plugs. For these, I used a short pigtail extension cord and these allowed me to use all 12 of the plugs.

Fantastic - had it about 2 months and has already saved the day twice thanks to the city deciding to “work” on the powerlines on my road. Bought it because a brownout fried my motherboard. With all my normal programs running (word, excel, cad, chrome, spotify) will run for about 45 minutes and about 25-30 with a game running. Easy to sync to computer.

Easy to use. Kept modem, router, network switch, NAS, and access point running for about 5 hours in a recent power outage. One thing to note is that this UPS cannot be turned on without AC power. I had another fully charged unit I attempted to move in a power outage, but because I turned it off, I ended up with a fully charged UPS I couldn’t use to charge devices.

I’ve had the unit about 2 weeks and tested in several times by unplugging from power. It ran quietly and stated coo during the tests. The battery runtime seemed on track with what I expected for my setup which includes a mini pc running pfsense, a wireless router, and a passive network hub. All devices ran smoothly while on battery power.

Work like it supposed to had power outage keep right on

I bought this as an open box item and its been flawless so far. The box had visible damage but the UPS was in perfect condition. So far it has been working without issues.

Works great where I live we have very heavy snowfall and it shuts powerlines down every now and then. I've had no issues with it at all.

CyberPower does the job perfectly and keeps everything protected!
