Customer Ratings & Reviews

This UPS works as expected. I have 2 PCs, Modem, Router, Firewall, Switch, Mesh Router, two monitors, one printer and it is at 20%!

IMPORTANT: Don't expect this to make your desktop PC last as long as a laptop. Don't connect cooking appliances to it. Don't connect more than about 12A worth of devices to it. If connected to a PC, make sure to set up the power reporting so that the computer can safely shut down if power remains off. Try to remember to test your battery every few months using a safe load such as a fan or a work light. These are basic, simple heavy duty home/small office backup batteries. The output quality is good enough for most computers and electronics, and there is excellent protection against low voltage and spikes. A single unit should be enough to protect the critical parts of a gaming setup or office workstation. You can use the menu to see how much power you are using, but the screen does not stay on. A sustained load of 900 watts or more could cause problems so be sure to check, I have several of these; one is protecting a home theater PC, a high end TV and a sound bar. I bought a long USB cable to connect the monitoring software on the PC, and another long cable to use the front charging port. I never use the charging port on the others.

We installed this backup for our server. This is working well because the power seems to go out consistently. This will help the system stay stable if the power goes out. It has been very useful and we have not had any problems.

I have a full desktop setup with important external drives. It gives plenty of backup battery power and can hibernate my system. A+

I experience short power outages at my apartment quite often. It was getting annoying while working on my desktop. My computer would blue screen every time after, so I went out and bought this backup battery. No issues since and it works great.

Simple to set-up and easy to use. Also, has lots of battery+surge protection outlets. Because of the two batteries, it is heavy.

With several power outages in Southern California as of late, and more than ever (thank you Santa Ana Winds), we’ve realized that we’ve needed an APS unit to salvage our go-to electronics as well as be able to maintain some comms during outages. This has saved us for every time we’ve had a spontaneous outage for whenever SoCal Edison decides to cut power. We have a smaller unit for another part of our internet setup outside as well and we’re good for a few hours. I greatly recommend buying one! If you are able for it to reduce in pricing as I did (bought during Black Friday), even better.

I have all major electronics on APC UPS's. Its a great feeling when you hear the unit beep as the house lights dim or temporarily go out and your television, internet and other devices continue to function as if nothing happened. If there is an outage, the display lets you know exactly how much time you have at current consumption levels. Sometimes our voltage goes as high as 130V, and its good to know that our components are getting a constant 120V. AVR, TV, Sub Woofer, Printers, Modem, Router, Apple TV, at least one light, and anything else are plugged into multiple APC UPS's. When we first moved in to this area a dozen years ago, there was a brownout at 2AM that caused the loss of data on a new computer, and I swore never again! I've been hooked on these units ever since. Customizable for sounds (or none) when there is an event. The Batteries are replaceable, and the staff at Batteries Plus will do it for you! If you think the price is expensive, wait until you have to retrieve date from a fried disc, and subject your private info to the purview strangers out of your presence. When (not if) you purchase one, remember, the higher the VA, the more time you have if there's an outage. I've seen and read that these can arrest a lightning strike, saving your equipment. I hope to never find out.

Works as intended. The display is useful in determining actual load on the UPS. It is also nice to see a test result slip on the side from the manufacturer.

Good quality and well made. Not sure why it's necessary to display the frequency of 60 Hz in the rotation of stat's on the display as if we might have some control over it. Output wattage is useful, though.

Its really easy to setup and see whats going on. Its saved my computer from surges during bad weather and given me time to shut down during a outage

I have always purchased APC over other brands because they are reliable. When you don't have surge protection at the electrical panel, the next best thing is to have APC battery backups. Our electricity goes out a few times a year for hours in Ohio and we have electrical storms pass through as well, so its best to protect your computers/TV's/etc. with a UPS. APC products work great!

Was looking for a long lasting UPS for emergency and this unit fits all the needs. Also, no issues with any noise and is very compact.

Works great nice slick look to it worth the money to save your computer components

Easy to use. Once in position you just plug in your devices and put the unit into the wall outlet. When the power goes out your devices stay on.

APC is being used in my home offices. very compact and easy to position. It's powering my 1000D dual-system PC with a 1600w corsair power supply and a 600w power supply. It also powers my dual monitors and other electronics. It delivers the power I need to keep my business equipment temporarily running during a blackout.

Well built and provides protection from power surges and failures. All sensitive electronics should have this type of protection, and this UPS delivers well.

I had a cyberpower one that actually caused damage to one of my devices that was attached to it when the cyberunit failed. New batteries in that one didn't work. Since I have used this same model in another location for my computer setup and it has been reliable for years to date, I decided to get another one of these.

First product did not startup, but Best Buy replaced it the same day i brought the product back with a same product. The staff was very helpful..

This one replaces the one I bought back in approximately 2010. I got a battery failure error during our last power blip, and so I figured it was time for a new one. These devices also provide a conditioned source of power, eliminating the risks of voltage fluctuations (especially now that I live in Las Vegas) and keeping my computers safe. I also bought one for my 3D printers which claim to tolerate power outages, but if you’ve ever tested that theory you’d see that sometimes you get print failures, or at least a very visible “print line,” when the power comes back and they try to resume printing. I can’t recommend a better UPS brand, and in particular this 1550VA model, for most any residential equipment power and protection needs.
