    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.

    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.

    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.

    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.

    A UPS should be considered a necessity in this day and age. Whether it's to protect your devices from spikes, brownouts, or generally "dirty" power, you're doing yourself and your gear a favor by having one of these.

    Life saver. We were having a lot of rolling brownouts in the summer. I hooked this up to our model and router and it was a godsend. Kept our internet up and going despite not having power.

    I love it. It has no flaws, and it has an extra battery, so if the power does go out, I can safely turn it off properly.

    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.

    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.
