    My previous apc model bit the dust during the last outage. I’ve never bought cyber power before, but this unit is the best size and shape for my cabinet. I hope this protects my kitchen entertainment center for as long as apc.

    Battery backups are a must, especially in CA with the rolling brownouts and the public safety power outages. Kind of a no brainer when trying to keep your equipment operational when the power is out.

    Bought for NAS storage device in my RV. Connects to NAS via USB so device shuts down correctly in the event of a power failure. Great for single smaller devices.

    My wife uses a CPAP at night. If the power goes out she nearly suffocates until she wakes up in a panic. This product saves lives as well as data.

    My old battery backup died right in the middle of a project. All the beeping and frustration! I calmed down, went straight to Best Buy where they had exactly what I wanted and carried on with my project. Nice system.

    I made this purchase after a similar product I had shorted out. This battery pack is working well and well worth the price I paid which was reasonable in comparison to other similar products. Very pleased with this item.

    Second purchase of this same item. Works like it is supposed to. We get a lot of near home lightning strikes. Peace of mind to have surge protection.

    We purchased this as a battery backup for our laptop computer, for an APS one which died. Every few years battery backups die. This was purchased at a better price than other stores. We are happy with it.

    An inexpensive but very reliable UPS. Cyberpower has been around a while now, and I find it to be as good or better than my APC units.

    Time will tell if this was a good investment. but for just a few dollars more compared to a standard surge protector, this seems like a smart investment to have the battery backup for the home modem and wifi.
