Customer Ratings & Reviews

I wanted a power backup to avoid nuisance power resets for an office setup of a computer, monitor, modem, voip telephone, and small computer speakers. As i had no method to measure actual power, i added up the claimed power ratings on each device with a resulting range of (600,870) watts. (energy = power * time) Using the CyberPower LE850G energy storage spec meant it should last for 3-4 minutes at this power level so i decided to take a chance on it given the price was good relative to some other products and had the right number of battery backup outlets for me. (note that not all the outlets are battery backups, this was the least expensive model that had enough for me.) After adding the ups to my system, it turns out that the software can report actual power use and my actual power use if about 10% of what i thought it was going to be based on adding the individual component power ratings as mentioned above. The end result is that the claimed battery backup time is about 30 to 40 minutes, which is enough for me. (note that i'm not trying to keep my system powered for hours as i'm assuming i'll always be around to take action as needed. however, the software can be set to turn off the computer when the battery is drained to a certain level, so it is reassuring that the computer will shut down gracefully even if i'm not there.) all in all, very pleased with resulting backup time suitable for my low-end home office needs without having to spend thousands of dollars for a larger ups. and, it was a good laugh to have done the math but reality meant a much better end result. your mileage (and math) may vary.

I have this mounted on the wall in a network closet for a school. It should provide 90 minutes or more of uptime for the one switch attached and the POE injectors for the WiFi network in the building.

I'm really enjoying my new Samsung 7" tablet. It's size is perfect for a carry along. I'll use it a lot when I don't need my laptop or need just a little more than my cell phone. The screen is very sharp and there are lots of apps you can use with it. Streaming movies is a breeze and makes watching a pleasant experience. I haven't explored all it's capabilities yet but I'm looking forward to seeing the many things it can do.

I am glad that I have chosen this UPS for my needs. I use it to power my computer and all accessories. its extremely reliable. Quite often, the power goes off and on, but I don't feel any interruption, while before having this UPS I would lose the work I am doing when the power interruption occurs. Its a great product at a very reasonable price. I recommend it for any person who needs a reliable UPS.

Cyber Power seems to keep their prices where you can actually afford their UPS. The quality is very good. I have purchased and replaced a few cyber power units. I have found it a lot less hassle to replace the unit rather than the batteries. I got this on sale so it eased the pain of having to replace the one I have that no longer holds a charge, also a cyber power. It ran for years so no complaints. Batteries don't last forever. Like the multi positionability (if that is a word). I have mine standing upright like in the picture. It's big, but the profile is fine for under the desk against the wall. I am just pleased with the cyber power units, they do the job, last a good while and are affordable. I repurpose the old units even though the battery doesn't work for surge suppression where I don't need battery backup.

Seems a bit steep in price, but the peace of mind is totally with the investment. Do your research before buying any battery backup systems. This one is economical for the features, giving more then just the bare minimum (a solid number of outlets, supplies power for a reasonable amount of time after losing power, surge protection, and isn't outrageously large in size).

My old battery backup finally died and I was in the market for a new one and checked out several different stores and brands. I had a Cyber Power in the past and decided I liked it better than any of the other brands I had. This unit has lots of outlets for all of my devices, looks good, and so far, it is working great.

I use it to power my computer and peripherals. During rainy season in South Florida, the power goes off and on during heavy storms plus many lightning strikes. I don't feel the interruptions any more, yet before I'd end up losing my work [and worse!]. Its a great product at a very reasonable price.

I bought this UPS 2 days before we had a tornado. Obviously, we lost power while I was in the basement. The UPS kept my wireless router online long enough for me to find out it was safe to come out of hiding. And the beeping was the only way I knew I still had a house left (very reassuring).

works great . i use it in my cnc shop . i was having some power spikes that would kick on the battery on the one i had and if you did not hit the button it would stay on battery until it died . with this one it does it automatically . problem solved

I had an older model Power Supply from another company and it was failing periodically after 3 years roughly of use. When it failed, it had a very sharp high pitched alarm. I would have to power everything connected down, power it down, to stop the alarm. This one has a mute button which you can turn off the alarm till you have time to shut it down. It also connects via USB to your PC so you can monitor many stats about it. I've had it several months so far and it has been working like a charm. Alarm has not sounded once. I love it.

Replacement unit for my old back-up. Previous unit was over 4 years old. Upgrades to larger unit for more outlets. Price was good and I like being able to see unit rather than get a surprise from online orders.

This does EVERYTHING my old UPS at almost half the cost. Great features AND it let's you know how long the battery will last based on what is plugged into it. GREAT VALUE!

Using this to replace my elderly UPS, I was able to mount this one on my desktop where it is convenient to use for all of my minor electronic devices. Lots of outlets with surge protect and enough outlets with the back up.

Good price and seems to be a good unit. Worked a lot during the recent bad weather until I could shut everything down completely. Upgraded from 650V and am very happy with the performance.

Over the years I have been dedicated to Best Power UPS (now Eaton), then APC when Best was bought out, and because of a problem with an APC unit, I switched this time to 2 CyberPower units. I have read that they use a "Simulated Sine Wave" on battery so I put a scope on the output to get a look at it. It turns out it is a modified square wave with 1/3 cycle high, 1/3 cycle at zero, and 1/3 cycle low. Well, maybe their higher end units are more "simulated" than that! At any rate, the UPS seems fine and works as expected. The PowerPanel Personal edition software is very limited. Apparently, though, I could have downloaded the PowerPanel Business edition instead for free. For the price, I rate this product as excellent.

I teach an indoor competitive drumline and we've been looking for something to provide power to some of our equipment when we move from a warmup area to the show space. Aka, we needed power in commute from A to B so there wasn't a delay in startup time. This puppy right here did the trick. It is able to provide temporary power to our laptop, digital mixer, and all attached electronics with no issues. It has solved many problems we'd had in the past because we had to wait for things to power back up after plugging back in. I would imagine it would equally as great in the home setting for this that need power when power goes away. Excellent back up battery!

I live in a rural community with iffy infrastructure. We get big storms here from Lake Michigan and we lose our electricity frequently and because I noticed my computer acting oddly when I had my electric dryer running I was looking for a safer option. When I was searching for a back up battery for our two computers. I looked on-line and I choose the Best Buy CyberPower 850 VA Battery Back-Up System for the following reasons; 1) This was the best price I found on-line. 2) The shipping was free. 3) It has plenty of joules 3) I feel safe and comfortable with this because it regulates power fluctuations, features surge protection that quickly diverts power spikes. No more getting up at night during a thunderstorm to unplug my electronics. This is just what I needed to safeguard my computers! I recently purchased two of these units and have recommended them several times over already.

This product works well and provides more outlets and joules protection than competitors product with similar specs. Software to manage this unit is user friendly.

Reasonable priced UPS. When power goes out, switches to battery without a glitch. Should have one for every computer, as well as base station for cordless phones.
