Customer Ratings & Reviews

I purchased this to replace a failed unit (not just a bad battery). It provides standby power for my ISP's cable modem, router, and switch to make sure my network remains online in the event of a power failure. This allows me to maintain my VoIP phone connection. It also provides power backup for my Networked Attached Storage device, allowing it to gracefully shutdown when power fails. My NAS unit connects to the UPS via a USB cable so it can immediately detect an outage. Runtime on battery is estimated at 53 minutes. Definitely worth the cost for the protection it provides.

I like having battery backups on devices, gives me a few minutes to turn everything off. I would think that all of them would include a surge protector, which is more important for Tv, VCR, Disc play or what ever similar you may have. Could probably use for a computer but I purchased more robust one at Best Buy and with much longer battery time to keep running devices.

The area that I live in is prone to short power outages anywhere from a few seconds to 3-4 hours every month or so. I have bigger CyberPower units on my tv and computers. I put this one in an inaccessible area to keep my incoming fiberoptic connection active. The UPS works great and we still get at least a couple of hours of internet access during power failures. I could probably extend it longer but attached USB fans to UPS to keep the fiberoptic equipment cool. I was hoping that the USB power ports would be inactive during power outages but they are still active and the fans drain the battery.

This unit will provide surge protection and a battery backup for our important devices. The battery backup will give us time to properly shut down the devices without the lose of valuable content.

With brown outs and total blackouts common here in NOLA I depend on good reliable power backup!

I had to replace a battery back up that went bad after many years of use. I picked out the CyberPower base on the good reviews that it got and that the price was reasonable for a battery backup. Installation was very simple and the outlets were arranged to handle block type plugs and regular plugs.

I bought this unit to power my electric recliners so when I loose power I am not stuck in my chair. It worked great when I lost power. Also had one lamp connected and it gave me light while I got some candles lit. The usb power ports are a plus. I would recommend this product.

Excellent quality and small size back-up With plenty of power reserve at 650VA. Easy install and start up... just plug in and enjoy the protection for computer and other electronics. I reviewed several available brands/models and this one was the best for the price. Highly recommend!

This unit is mounted on the wall next to the gateway and wireless router. It installed easily and is working well. I chose it for its sine-wave output, size and cost. I did not purchase another manufacturer's competitively priced similar unit because it could not be mounted to the wall.

Works great, and was a good price. It's been a while since I bought a UPS, and they have definitely gotten a lot lighter since the last one I bought. They usually weigh as much as a car battery. This one weighed about as much as a typical power strip.

These battery backup/surge protectors are great. I have 2 that I use for my 3D printers. I can assure you that they work. When the power goes out my printers keep printing without losing a beat.. Just follow the instructions and you will be fine.

After multiple power outages, my POE switch for my security cameras failed to restart. I purchased the CyberPower 650VA to protect my new security camera system. In addition, my system will now keep running for a few hours if I lose power.

Easy to set up and compact for tight spots. Plenty of both surge protected as well as regular outlets.

Excellent backup time for about $50 (on sale) and it includes 2 built-in high-powered (2.4 amp) USB ports which means I don't need to use the adapters that came with my cellphone and my MagicJack (VOIP) device. Nice! I've now got three of these UPSs protecting my computers and my network devices.

Excellent UPS. We have several of them that work great for surge protection and battery backup.

Have had the power go out a couple times and it works great. My only issue is the load beeping that continues goes on until you either shut it off or the power turns on... threw away the directions so unsure if it can be turned off without shutting the whole battery off.

Very good product! Takes a while to charge fully (almost 6 hours) The duration of time you can use it once charged depends on what you have plugged in. Video Game Consoles literally deplete the entire battery in less than 5 minutes. Watching TV, it will last hours though.

I've owned multiple versions of this companies' power supply battery backup. They last for about three years and I've never had damage to my connected electronics during storms or outages. The built in alarm sounds when the battery becomes active. This is a great unit for the price.

Operates as expected. Watch the load you plug into this unit

I've learned to use and recommend CyberPower UPS's over any others, especially the older, maybe more popular brand. I've seen their batteries last almost forever, and the units are cheaper than others.
