Customer Ratings & Reviews

The CyberPower - 450VA Battery Back-Up was bought to keep my cable box from shutting down when there is a power surge do to the electric changing grids. It does work for that purpose.

Appreciate the ease of setup and use of this back-up system. Very cost effective. Much lighter weight than my old one.

So far it works fine although in retrospect I should have looked into a higher capacity UPS. It won't really keep anything powered for long but it is ok if you want to be able to make sure everything is fine before shutting down whatever is plugged into it before the battery runs out...although there won't be much time to resolve whatever is being done on a computer or whatever it may be used for.

This is the third UPS I’ve purchased. I installed them on my TVs and this one is on my wireless printer. Protection for nearby lightening strikes and surges.

Been using this product for years protect your like Tronics usually last pretty good while and all I Gotta worry about is replacing this once in a while cheaper than replacing your TV etc.

We wanted to get a battery backup for our desktop computer. The sales representative showed us the store's offerings and helped us pick out the right on for us.

This is a good product and has always worked for me thank you.Always will you from damage to ur computer

Nice to have especially when power goes out helps keep my modem running and protect from power surges

This backup is all you need for saving your work when the power goes out.

Purchased the CyberPower 450VA battery back-up to protect power to my home wifi system and prevent programming loss on my printer. Works as advertised.

I need to have my electrics secured. The last one failed on me and I was in needed for a new one. The price was grate and works perfectly fine.

Can’t beat it for the price. Works as advertised and should last for a while.

This works fine. I wish it could have had more outlets for battery (half are just surge protected), but after 8hrs of charging, it keeps your devices running during a power flicker.

Have the larger voltage of this powerstrip and really like them. This size fits perfectly on my nightstand and I can charge all my devices plus my alarm clock. When the power goes out everything still works.

It works well, and we had one power outage, it gave us the time to shut our computer down gracefully.

It is a battery back up what more do you want me to say except that it works and I didn’t have to return it. Yay me

It's nice to have something to protect your expensive devices.

I use this to provide temporary power for a cable box, clock, and cordless phone for the 10 or 15 seconds between a power outage and the backup generator kicking in..works great at a reasonable price.

Works very well as advertised. This was a replacement for a much smaller unit

This small battery was purchased to provide back-to a wi-fi router. (Modem is plugged into a larger CyberPower battery back-up. Both units appear to be working, though they haven't been tested by a real power outage.
