Customer Ratings & Reviews

I’ve only used this for a couple weeks and my computer hasn’t arrived yet, but it’s worked perfectly in a couple of power outages that we’ve had. I keep my iPad Pro plugged into it and it has a couple of very handy USB power plugs in it too. It’s a nice compact size with plenty of plugs for my uses.

My girlfriend works from home. She has to keep computer and internet connection live. I have this one connected to my essential internet devices - modem, router and switch. With 650VA, it should be able to keep connection alive for hours, even if power goes out for long time.

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.

Very good device, since i work from home it helped during a sudden outage that kept my devices turned on.

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

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.

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

Great little UPS backup for protecting my music recording gear and outboard devices while in a session. I protect all of my studio gear from under-voltage, dropout and voltage spike damage. This is just an addition to my other UPS units that keep my gear protected.

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 !

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.

Works great for 4 game consoles, 2 TVs and the internet router! If using it for a gaming PC, be careful not using a high wattage for a power supply.

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.

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.

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.

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.

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.

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!

A surge blew up my printer. Rather than getting another cheap surge protectorI went with this. The instructions day to put laser printers in one of the four unbacked up outlets so I did. But I also have a home server and I lucked out with the surge. Now it is plugged into one of the four back up power outlets.

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.
