Customers are saying

Customers admire the 1000VA Battery Back-Up System for its exceptional battery life, overall performance, ease of use, and surge protection capabilities. Many appreciate its compact size, reasonable price, and the abundance of outlets it offers. While some users have noted that the device can be a bit noisy when activated and slightly heavy, and that the instructions could be clearer, the positive aspects appear to outweigh these concerns.

This summary was generated by AI based on customer reviews.

The vast majority of our reviews come from verified purchases. Reviews from customers may include My Best Buy members, employees, and Tech Insider Network members (as tagged).

    Bought this to protect my electronics after some electrical problems. Definitely protected them from the power surges. It would be great though if they could manage to make them smaller.

    I recently experienced some scary power drops in my home, and having recently purchased a nice new desktop PC, I immediately researched and bought this Cyberpower UPS. So far I love it. The LCD display is a nice touch, and I have it attached to my PC via USB so I can monitor power stats on my desktop. Note - you need to go to Cyberpower's website to download it.

    I purchased this for my computer since I'm working from home more. I have experienced a couple brown outs during windy periods and the UPS has only clicked on and back off. I let the device plugged in overnight before using it when it arrived per instructions even though it came fully charged.

    I bought 1 of these last year and have seen first hand it works great during power outages. I bought 2 more as gifts to the gamers in my family. It's just as nice safety measure to have expensive equipment hooked up to and it's protecting your stuff incase of sudden power outages giving you time to shut down things properly.

    Currently using as a back up for my home theater gear (TV, Receiver, NVIDIA, Fire TV, subwoofers). Has handled a few power blips from storms with no issue. The ability to turn off the alarm sound is a nice feature too. Very happy with this purchase.
