Customer Ratings & Reviews

Perfect size. Our older one died, we needed a newer simpler replacement. This one was in our price range and so far, it works well. Easy to install.

I have always been happy with CyberPower back ups. They saved my electronics when my homes power was having issue and sending surges through the house. They saved us by locking down power when they got flooded, preventing many issues. They are heavy, especially when charged. If they die a few times, they are done. But they do their job

When we bought this, it has some weird rattle noise from the inside like there are loose screws or something. It works perfectly though, and has allowed us to not lose power on a few mission critical appliances in our office!

This is perfect especially if your power turns off for a split second during a storm. This keeps our internet and computers from turning off with that flicker of power during big storms.

Very compact size saves space on my shelf. It is very easy to set up. Comes om immediately if any power failure occurs. I support this product

Small, compact, affordable and easy to use. Recommend an overnight charge on the battery before use.

Cyber Power 650VA, is a good backup power supply. It has 8 outlets with 4 battery power outlets to protect any electronic devices. In my case an i3 computer and a 20" screen. It provides clean power against brown-outs and occasional power drops, specially in Florida summer. During power outage this UPS provide me ample time to save my work and shutdown computer. It has excellent 3 yr. Warranty. I definitely recommend cyber power 650VA. It's a great buy.

great battery backup. perfect for small electronics or appliances. easy to setup and use.. would definitely recommend

So far so good. It's only been a month so too soon to tell.

I like the idea of having a protective power strip cord with a built in battery so if the power goes out by storm or tripped breaker, i have time to shut devices down correctly without losing progress!

This worked perfectly for my "network closet" where there are miscellaneous, relatively low-powered devices that need backup. The fact that there are two USB ports are great also since they can keep a USB flashlight and other devices charged. I've preferred Cyberpower over APC for years based on how they handle power fluctuations. Typically my APC units have just shut down, while the Cyberpower ones handle the fluctuation by switching to battery - even for a short time.

Works as advertised and simple to use. Only reason I didn’t give it 5 stars is that when the power goes and and it activates it makes a been every minute or two. It gets annoying, but at least you know it is working.

Works as described, my fiber internet usually takes 15-20 minutes to come back after an outage, even if it’s just a flicker, This keeps it on giving me enough time to warn my work about the outage. Not sure how I lived so long without one.

I use it as a battery backup & surge protector. Have had no electrical drops or power outages yet but, I'm told it works well to protect my computer.

This seems to work great so far although I haven’t had any power glitches to test it out. I got it to plug in my TMobile internet router so that power blips don’t cause the internet connection to quit. It’s probably overkill but ok so far.

Easy to set up plug and play great protection. Will save my computer when the power goes out.

Protects my computers from excessive power surges all the time, great price and quality

Great price and it’s already had to be used and did it’s job perfectly

My old backup battery recently ‘died’ and I had no idea what to replace it with. Finding this product at Best Buy was simple. I told the salesperson what I needed, and he immediately directed me to a variety of options. This one was exactly in the price range I had in mind, so I purchased it. It was easy to install and I was quickly back in business. Good product and great customer service, two of the reasons I keep returning to Best Buy. I’ve now had it about a month and it’s working fine!

We purchase these for our critical desktops on campus. They last and work great, especially in Florida where surges and sags happen frequently.
