Customer Ratings & Reviews

Works excellent for my home office. My last CyberPower Battery Backup lasted 10 years. The Best Buy dude told me this one will do the same!

Intended to keep a laptop alive for the remainder of our church service is laptop runs out. Should have lots of capacity, but watch out - the total power available is not directly related to the backup time, which can really be minutes. But this was the most we could afford, so buyer -do more research than I do. We have to turn off all warnings of course, so the unit lights give almost no indication of charge.

CyberPower - 650VA Battery Back-Up System requires an initial 8 hour charge before it is expected to perform as promised. It beeps (YES, BEEPS OF THIS NATURE SHOULD ANNOY A USER TO CONSIDER OBJECTIVE ACTION!!) when necessary; otherwise it sits there quietly protecting my modem, router, network switch and NAS devices. Two 450As and one 950A provide reliable services on similar devices. As I read it, I can attach my Officejet printers to the Surge (NOT BATTERY/SURGE) outlets but I have not yet done so since I prefer to put them on separate CyberPower units which I am yet to research.

Excellent back-ups very important for you computer

Man, I needed this. The power went out like clockwork for 3 weeks and we had TV, heat and internet. The kids were happy.

My wife and I use this in our office as a surge protector for our computers. Excelllent for power surges or short outages.

This is a nice size battery back up / surge protector for a computer set up. Plenty of outlets for monitor, computer and all accessories that need to be plugged in

I bought this for any emergency, and it proved its worth when the power went out

Very happy with the battery backup. We have power failures and this has been a life saver so to speak

Great backup battery for a router or pc. I have a gaming pc and during a power outage the battery last about 30 min.

Good battery back up system for a TV and one extra peripheral but not great for a more power demanding load.

Set up was easy and works great. We already had a power outage and was able to still us my Computer while the power was out.

If you are looking for a battery backup, this does the job. It is nice that if power goes out, it allows you some time to shut down your equipment

No more constantly running to unplug the router. The constant storms we have had to endure these last few weeks and I feel safe to surf the net plugged into this baby.

We just replaced our last one which lasted 6 years with the same model. This is especially a must have in the lightning capital of the world

Have had good luck with Cyber Power battery backups in the past, and so far so good with this one.

Having to run everything off generators right now so having a battery back up is a necessity. Has enough to hold me over until the power returns

Extremely helpful during blackouts. Was very easy to hook up.

Bought this when my old model UPS kept “eating” replacement batteries. This one works well and so far (7/2020) the battery has been fine.

This is a basic UPS that was affordable for light weight devices. It's lighter than some of the other UPS devices on the market and doesn't need to be connected before being turned on to start charging. It has worked properly so far.
