Customers are saying

Customers are pleased with the 450VA Battery Back-Up System's long battery life, strong performance, compact size, and affordable price. Many appreciate its surge protection and ease of use, finding it simple to set up and operate. While some users wish for a USB port and find the unit's weight or alarm to be a minor drawback, the overall feedback is positive. The number of outlets is also frequently praised as sufficient.

    I have not needed the back up power yet. It is better to have and not need. Than to need and not have. Unit is compact and easy to use when needed.

    This device really helps you if you have a nas or anything that needs to be charged so I recommend getting this it's not at a very bad price and you have surge protection for both signs and the battery backup again to charge anything you need at that moment if the power went out

    I really like this UPS. Good price for the security of not loosing power. It has a good number of plug-ins and it’s not too large it fit by my computer. I can fit all my components in this unit and it still has a few extra plugins.

    Great battery backup. Easy to use and very needed since we have a lot of temporary power outages. My computers were suffering from turning off in the middle of work when the power goes out for a minute or two.

    Works great not only for computers and other computer-related items, But also as a Backup for Lift Chairs for Elderly during a power outage My mother was stuck in her lift chair for more than an hour and had to use the restroom couldn't get up until the power came back on after the storm had passed, we talked on the phone for a bit and I got an idea to buy it for her chair so at least she could get out of it during a power outage... Maybe you could have a new market for it selling it as lift chair battery back up... She loves it and has used it twice when the power has gone out during other storms so far she has a lamp plugged into as well so she can see where she's going once she gets out of the chair...

    So far so good. Been using for a month now. One power spike has occurred, but seems the device caught it as I didn't notice any flickering with the devices plugged in. If any power outage happens, I'll update my review to reflect my thoughts. So far very happy with the peace of mind knowing my Devices are well protected.

    Haven’t had any issues so far. Have my whole PC setup connected to this. Bought this smaller one more for the surge protection more than the battery backup, but if I can have a few minutes to shut off my pc when the power goes out then that is even better.

    I needed a battery backup that was reasonably priced and provided the battery power I needed to shut down my computer and monitor should I experience a power outage. The CyberPower - 450VA Battery Backup System fit the bill perfectly.

    This is a good batter backup , great price and has enough outlets to provide both surge protection and backup power. Bought to power a CPAP machine during the night in case power went out and has more than enough power to provide backup to the unit for several hours.
