Customer Ratings & Reviews

I bought this at my local Best Buy after my old splitter broke and I fell in love. I was able to plug everything in and all my internet related things have a power backup. 10/10 product

This CyberPower - 450VA Battery Back-Up System - Black is great. All you need to do is charge it for 8 hours before you use it and then plug everything into it.

I recommend these backups to anyone. They work great! Very well priced. I use them for my business, so productivity never stops. You won't regret it. Buy it today!

I got a battery backup years ago, and this newer one is so much lighter and effective. Some of us still like the battery backup option for our delicate electronics.

Great product. This is my second one. My last one lasted over 10 years and I never had any issues with it so it was a no brainer when I needed a new one.

I needed to protect some computer type equipment. This is big enough to handle power fluctuations and small enough to easily fit with the rest of the equipment.

Unit simply plugs onto your house power and charges its battery for future use. Simple application, effective protection aganst power loss until my Generac kicks in.

I have no complaints I bought it and I have multiple things hooked up to it it's awesome does the job I suggest everyone buy this if u have a computer or electronics

Due to working from home, and with Florida weather knocking out power from time to time, needed a decent battery backup and thisnunit does the job perfectly

This power/surge backup system has saved me numerous times since installed. I have two separate backups in different rooms. TV, computers, modem, wireless.

I'm an engineer and run 4 computers simultaneously. I live in an area that has a lot of thunderstorms and power outages. This unit has saved my bacon several times.

I have purchased many of these UPS devices over the years and have never had any negative issues with this brand. Less expensive than APC and does the same job.

Has kept my router online when the power goes out so I don't have to reset all my home electronic settings with my home automation. Exactly what I needed.

My old battery back up of UPS went bad. NO time to waste and just needed a good solid replacement. Went to the store picked it out and brought it home. How easy

MY OLD BACKUP POWER UNIT (OVER 10 YEARS OLD) GAVE UP 50% SO I PURCHASED THIS UNIT AT A GREAT PRICE (CYBERPOWER) THE GEEKS AGAIN RECOMENDED THE NEW ONE.

It worked great & kept my computer on during a storm long enough so I could do shut down. Also had other things plugged into it. It did what I expected.

So I got this for my mother's living room setup which has a 50in Plasma Smart TV, Router/Modem, Xfinity X1 DVR, Sound Bar & Bluray player and I know we had the TV, Modem/router, sound bar and the X1 box on the battery side and within a few seconds of everything running it start alarming as if a power loss or too much pull from the battery side, didn't check exactly. As soon as I took one or two of the items off, it was fine. I think I left it with the TV and X1 DVR on the backup side and the others on non-battery backup.

Needed more outlets for my computer, router, extra hard drive and printer, that would not overload or block extra outlets. This was perfect for that purpose.

So far so good. I won't know for sure how well the backup battery works until we have a power outage, but the space between the outlets was adequate for my adapters.

I bought this to power my access point and internet during brownouts or spikes After charging, I pulled power cord. Kept devices up for over an hour.
