It gets the job done with tons of time to spare in battery reserves.

This was the perfect addition to my whole house generator system. It keeps my Router and internet up and running while the generator switches over. Great backup for a great price.

My goal is to keep my home network operational through power flickers. I have 4 low power consumption devices (including a Synology NAS) plugged into this unit, and it reports that it has the capacity to run them for almost 8 hours if the power is off. I like the size. I don't notice it making noise. My only negative is that the power plugs are too close together to plug in transformers (wall warts). I could only use 2 of the protected outlets directly, and had to use an extension cord (not best practice) to plug in the remaining 2 devices.

It works very well. I like the display and the 900 Watt capacity.

Easy to install and configure on a server and necessary with power glitches!

we shopped for awhile before we decided on this product, it was a good price

We selected this battery/power backup because it was the largest size in terms of time for battery backup and it is smaller than expected. Sits upright with the cords plugged in to the back so it stays neat and tidy. Very happy with purchase.

Excellent product you can protect many devices with this product

I use this backup for my computer and other associated electronics, as digital work carries the danger of brownouts or other power outages. The display updates how long its battery will last when items plugged into it are turned on, turned off, reduce their power draw, etc. and is very useful in knowing how long you have to save your work. It also only emits two beeps every few seconds when it's on battery power, as opposed to smaller wattage models constantly emitting a high-pitched whine while on batter power. Would definitely recommend!

My PC has a 750w power supply so I wanted a UPS that could handle that draw on top of a 40" monitor, external hard drive, etc. The same day I plugged everything in, the girls turned on their hairdryers and popped the circuit breaker. Without the UPS, I risked corrupting my hard drives, premature PS failure, frying the motherboard from surges.... Nice to have peace of mind now.

Does exactly what it's supposed to do, protects cable modem and WiFi router.

My old UPS backup just croaked one morning. After researching the Cybber Power 1500va unit. It has much more power and backup time of almost 260mins with everything at my workstation attached. It has already kicked in with power glitches here and an hour of no power. Worked perfect. Recharged in about an hour. Highly recommended backup device.

Great Backup Surge protector! Nice to know that your computer wont be damaged, and that i'll have a little more time on my computer after power goes out. Would Highly Recommend.

Wanted to upgrade to a newer backup battery and chose this unit because of the price and reviews. So far its quietly fulfilling its intended need and it is a perfect fit for the space where it has been placed.

My old ups of similar size finally decided to stop charging on me so I needed a new one. This one actually has a bit more capacity and seems to last a bit longer than my old one did for my main server system. Hopefully it will last the 15+ years that my last one did but I suppose time will tell on that. It has at least a 30 minute run time with what I use it for, which is great for when ameren cilco decides to do maintenance in my area and not tell anyone. My system stays up and running for these short outages.

like the fact it has USB capabilities. Very solid build. easy to set up.

I tried against apc and this one last more. The software is better too

So far, this product is working fine and have had no problems with it.

I bought this item as a battery backup for my computer system as my previous one had failed after 8 yrs. Works as designed. Software is a little flaky and nags at times. But the unit works excellent.

I purchased this UPS for one main reason -- I wanted my computer, monitor, special telephone equipment, and cable/phone routers PROTECTED against both brownouts and surges! For me, this is all essential communication equipment upon which I depend for my links to the outside world. Since my purchase, the CyberPower UPS has been "tested" a number of times, and I'm very happy that I have it protecting my equipment from electrical danger! More times than I can count so far, the power has dropped out, periods ranging from several hours to seconds. So far, no damages what-so-ever! It's just not POSSIBLE to do better than that! Given the number of cable service telephones, cell phones needing powered base stations etc, as best I can tell, I'm the ONLY one around with power AND access to emergency personnel in case of emengencies. THAT's both a relief and a blessing for those friends and neighbors who might at some point need the access.
