Customer Ratings & Reviews

Glad I bought this. Gives me piece of mind to know I won't have to worry about power fluxuations messing up my equipment. Plugged my modem into it too. Feeling very good about this purchase.

When I needed an affordable, efficient, compact surge and back-up system in a hurry, BestBuy has the answer. I received the purchase in two days and was able to continue. It was easy to set-up, the cord was the length I needed and the instructions were straightforward. I only needed 8 hours to let it back. I'm glad it was purchased and would purchase one again for meeting my specific needs.

Little or no difference between this unit and APC UPS. Both provide power during power loss and will act as a surge protector. CyberPower does tend to be less expensive so there is that.

Works well and reliable. Lower profile device fits in our space well and functions easily.

I bought this surge protector backup after my internet modem power supply got fried in a storm. Since buying it there have been no bad storms so I cannot say how well it holds up or how long the power backup will last. It was easy to understand the directions and turn off the alarm since I didn't want to hear it in the middle of the night should there be a power failure.

Great item for electrical items like your computer

Works as expected perfet size................... .

Great price for a great product. Not as heavy as others I've owned like it in the past.

Long power outages (5 to 13 hours) happen where I live as often as twice a month, and since we're in a dead zone for cell coverage we have to use wireless at home, so without power I don't even have a phone connection. This UPS is just right for keeping my cable modem, wired/wireless network and VOIP phone working during a long power outage. It's the kind of thing where there's not a lot to say about it. Either it works when you need it, or not. This works.

In my application, providing backup to our cellular wifi modem, it has worked superbly. We had some modifications to the house done that involved having the power to the circuit feeding it temporarily shut down, and it kept our internet and wifi going over the entire house and again the next day after recharging overnight. The outage the 2nd day was not as long, but still was several hours both days.

I got 3 of these tied to my mesh routers, computers, and fiber connector from ATT. All are now backup on battery power and with my loading all of these give me 15-60 mins of backup time which is more than enough. 60 mins is the fiber optic converter and it's the only load. and 15 minutes is 3 monitors, 2 computers, router, and printer tied to it ;).

Works well to date. Easy to install. Just enough power for my use and enough connections for mybuse.

The CyberPower - 450VA Battery Back-Up System is a good starter UPS that protects your equipment against short power flickers or outage. It won't last long, hence the lower price compared to the other versions.

This product was a lot smaller (more compact) than the one I was replacing. The right price and the right fit.

Bought this to replace an APC unit that was way bigger than what I needed. The APC unit had been in used for almost 10 years and was on it's third battery when the battery gave up the ghost. This protects what I need covered and cost less than a replacement battery.

Good replacement from what we had. Ease of purchasing and pick up was terrific

I chose this CyberPower because it had a good mix of outlets and battery power combined with a nice size.

I am using this in conjunction with the ISPs router to keep phone service in the house when the power goes out for a bit. However, I have a high powered amplifier attached to the surge protector portion, and once in a while the protection circuit trips when I turn it on. This causes all items attaced to the APC to lose power, which resets the router. A little frustrating, but the security of it protecting other items and having 10 minutes of backup power for the router is worth it.

I've been buying CyberPower Battery back-ups for a few years now. The latest model I bought (in-store from Best Buy) is smaller an lighter which I like, but has a flaw previous models did not. They changed how the plugs are arranged. The grounding socket used to be lined up along the outside of the unit, now it is not so I can only use 3 of the 4 sockets since the way the plugs are block the other socket. Previously I could use all the sockets since it was arranged so it would not be blocked.

Works great for my appliances for when the power is out
