    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...

    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.

    Worked as promised. The power went out and all my devices connected to the system kept on working as if nothing had happened. Very good value for the return on not losing the wi-fi and computer during a blackout.

    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.

    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.

    This is a great resource for our home entertainment system, which includes a smart TV, router, PS5, and Switch. It was easy to install, and it doesn't take up too much space.

    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.

    The Extended Battery allows You to safely maintain and turn off all equipments when a power outage, or a peak in energy levels occur. Safe TV means a Happy Customer and with the Sales Representative that helped Us it was a WOW transaction.

    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.

    My two year old APC UPS battery died. I use a UPS for my desktop. I went looking for something less expensive and found this brand. It has two outlets connected to the battery and six others that are surge protected.

    Bought this to use with a massage chair. It is just the right size and also allows us to plug in chargers. Like the fact that it will keep things running if we loose power. Won't be stuck in the chair! LOL.

    I charged the device for a day and plugged it right in and it worked. There are separate sides for with battery backup and just surge suppression. The outlets are a decent so the larger plugs still fit.
