Customer Ratings & Reviews

I also own a CP1350C for my main desktop and router. This unit is for my Smart Home server (an HP desktop also bought from BB!) and a few Raspberry Pis. I like CyberPower's software, the price is competitive with APC and I've been very happy with the results in the few outages I have experienced.

I live in rural area and it seems we have more than our share of power fails. Nearly every time this happened I would loose the Excel document updates. Hours of work vanished. Now with the battery back up I have been saved many times. One save paid for itself !

It does what I need it to, 4 battery backup plus surge protected outlets, 4 surge protected only. Good value

I like this equipment very much. Spec's are good and the unit powered right up out of the box. It has run flawlessly since my purchase.

I am pleased with this product and happy that I chose to have a battery back-up system. I have installed and owned mine for only one month, and have had no power outages during that time. However, I am confident that this device will adequately protect my files and all data from elimination from power failures.

Got this and it has worked like a charm! There are unexpected storms here in SOFO, so this was much needed for the random outages!

I bought this misreading the 650VA as 650W, which was a mistake on my part. I returned it after testing it out and realizing it could not handle my computer load. However, this product works is quite a steal for the price. I recommend it for anyone looking to run low load electronics from it.

I live in FL. which is the lighting capital of the world. We need protection for our electronic items and this will protect it. I will be working from home and this is necessary to protect my investments because my employer isn't paying for it. Don't wait until it's too late. Get yourself one.

CyberPower - 650VA Battery Back-Up System - Black. It works as described. Beeps when activated. Comes in a box. Plugs in a wall.

Life saver. I live in area that have I lot of electrical outages. Not good when you work from home. This keep me working with out missing a beat.

One surprise: it trips the circuit breaker and stops charging if you place it on the ground vertically... but it says that in the instructions (I just missed it). You can attach it vertically to a surface, and you can also lay it flat. I cannot say how long it will work during a power outage because we have not had one yet, but I had a smaller CyberPower UPS that worked well enough.

When the lights blink during a thunderstorm, my equipment stays on. When buying a battery backup unit, be sure you get the correct size for the devices you have. This is a relatively small investment that pays big dividends by protecting your router, cable modem, computer, TV, etc. from power glitches and outages.

No more issues on my gaming PC with power! I would highly recommend this.

I bought this for my 86-year-old Mother. Her power goes out and has a hard time getting the tv to come back on. Now she can keep it on for a while and turn it off herself if needed. Comes back on easier that way.

It does everything I expect it to do. It is protecting my computer equipment and other items in the house. I would recommend it to anyone who needs to protect computer and any other electronic equipment. The price is right and you get good value for the purchase. I would think this is a good purchase for just about anyone.

Good product! Saves my equipment when dealing with storms and lighting here in FL. Bought one for each room and main living area and plug in all crucial electronics. Would highly recommend

My electric company notified me they’ll be working on my street for the next 4 months and to expect scheduled outages! Working for home at least part time I needed to ensure reliable power to my computer to at least save the work I was doing. I like the cyber power ups versions because you can mute the blaring alarms so when the power flickers in the middle of the night you don’t have alarms going off everywhere.

We have had several recent power outages, and the CyberPower 650VA performed very well in alerting us and maintaining power to our devices so that we could shut down our computers properly. I bought two, and so far, they have been trouble free and working just fine!

I prefer to use a battery on all my important electronic devices as they provide a better layer of protection than most power strips. This device provides more than enough support for any computer or other device and a price point often lower than the big brand. Good protection, good value. I have several.

Nice battery backup device. Bought this to replace one that went bad after 16 years.
