Customers are saying

Customers commend the 1000VA Battery Back-Up System for its amazing battery life, overall performance, and ease of use. Many appreciate the surge protection, reasonable price, and smaller size, as well as the ample number of outlets and informative display. However, some customers have noted that the device can be noisy and a little heavy, and the instructions could be more helpful.

    Using to power xbox one and tv during power outages so I don't lose saved games. Prevents restarting system when power just flickers and comes back on.

    Really sturdy. But heat attracts bugs. Have it in a area where it can air cool. Can keep my PC up really well during a surge.

    I purchased this back up battery with surge suppression to safeguard my embroidery and quilting machines. I actually have two of them now. I really like the change in design of my newer model. The back up battery is a lifesaver when I am working on a project and the power goes out. It gives me enough time to finish up what I'm doing, save the project and then shut down the machines properly.

    I haven't experienced a power outage since purchasing this CyberPower model. I've used CyberPower battery back-up systems in the past and the 1000Va is an upgrade (and heavier) from what I've used before. A nice detail is the ability to replace the internal battery in the future instead of having to purchase a new back-up system.

    I've had one to run and protect my modem, router, and Blink Sync 2 module and have had no issues. Just bought another for my PC to replace an APC that wasn't getting the job done.

    Works great, had a power outage and kept my Wi-Fi running for two hours until the lights came back on. A must have for anyone who wants to protect their expensive technology.

    I bought two these UPSs and have already had them tested during a 12 hour power outage recently. They preformed brilliantly and I would more then recommend them for purchase. I manage 3 NAS devices in my home totalling more then 45TBs of critical data and these babies worked like a charm. If anything they're a bit overkill but for the price would purchase again without hesitation.

    Our old UPS died and bought the CyberPower UPS to replace it. The CyberPower UPS was easy to set up and provides the backup power we need when the power goes out.

    CyberPower is my preferred battery backup company. The outlets are well-spaced to deal with large plugs. Backup lasts reasonably long. I have had a couple of these die from some very strong surges, but they protected every device connected to them, so they did their job well.

    If you are going to use a UPS, I would go with this. I got the version lower than this and it burned out after 1 power outage. This one has lasted about 2 years and multiple power outages.

    I have not had a chance to really test it for how long my router will stay on if we have a power outage. It was easy to set up, it is smaller than the replacement for a larger one I had from the same company that I have had for 3 or 4 years. So it is easier for me to plug things into.
